Like a Boss: The Philips Fidelio X2 Measurements

Click on graphs image to download .pdf for closer inspection.

Raw frequency response plots for the X2 show a headphone that is very immune to positional changes effecting sound quality. Even the high frequencies show very little change.

Compensated frequency response plots show a headphone with an overall modest warm tilt. Primary driver resonance is shown by the peak at 60Hz with a 12dB/octave roll-off below, which is natural for an open, dynamic headphone.

Though a little bumpy and having a warm tilt, the response from 60Hz to about 5.5kHz is essentially a straight line. Even though it get substantially more noisy, the response above 5.5kHz also does a goos job of following the line established. Take a good hard look at this tilt, I think it may represent something very close to what I would consider neutral.

There is a substantial notch between 5-9kHz. This notch was established as a target response during the development of the X2 in blind tests by highly qualified listeners. I did here the X1 as being a bit more edgy than the X2; the smoother sound of the X2 might indeed be the result of this notch.

30Hz square wave response shows a significant sway-back due to the loss of low bass and phase changes as the driver goes below its primary resonance at 60Hz. Coupled with the related rise in low frequency distortion in the THD plots I would have expected a looser sounding bass response than that which I heard in listening. In email exchanges with the Philips engineer I was told that the trick here is to not overemphasize the bass too much as the looseness will become apparent rapidly at some point. I did hear the bass as slightly loose, but no where near what I would have expected from these measurements.

300Hz square wave response has good shape—first overshoot is about the right magnitude; signal achieves a generally flat top quickly—but there is significant raggedness seen, which is also observed in the impulse response. Generally, when I see this I tend to think the headphones are going to sound harsh. While I did here a little edginess with these cans I did not hear nearly the amount I expected. And the X1, which exhibits significantly less noise than the X2, sounded edgier to me. I'm not sure I can explain that. Were I to guess, it might be that all the fine tuning of the headphone's frequency response has this sort of effect on its time domain response. Dunno.

Apart from the rise in the bass, THD+noise plots show a relatively low distortion headphone with good power handling until you reach 5kHz. Here again, the tuning needed to create the notch between 5-9kHz may create some distortion by-products. Impedance plots show a nominally 35 Ohm headphone with a rise to 45 Ohms at 60Hz at the primary driver resonance. This bump may cause some bloom in the bass if used with a high output impedance amp like a tube OTL design. I would not recommend these cans for use with these types of amps. I suggest 2 Ohm or less output impedance.

Isolation plot shows a little more attenuation above 1kHz than the average open headphone, but below 1kHz virtually none. This is a headphone for listening in quiet environs.

Other than the general shape of the frequency response plot (which I think might be very good, and I'll be looking for more headphones with a similar response), I find these measurements to be significantly poorer looking than the headphones sound. I suspect Philips may work on getting the time domain responses (300Hz square wave, impulse response) to be a little cleaner, but I have to say again that I found these cans much better sounding than they look on paper.

Thanks Tyll for review!

BarbecueGamer's picture

I trust your opinion over any other. We both have the same tastes, I have always agreed with you. So, I was hoping you could make my decision much easier. I'd greatly appreciate it if you could please tell me which headphone do you think has better sound, the NAD Viso HP50 or the Sennheiser Momentum?

Tyll Hertsens's picture
Personally, I like the HP50 better.
Bryan B.'s picture

Thanks for the review of the X2, I was just wondering in regards to the X1's... They have that magical bass (IMO), that overpowers everything and makes EDM so much fun (as I thought the treble still had that sparkle).

If I get the X2s will I lose that overpowering bass or can I still EQ it? It was just weird with the X1s I will go to work the next day and still be rocking to a bass signature from last's nights track, which I have never had before with a headphone.

-Gast-'s picture

Im not the one you asked, but a short opinion on the Viso: Its great sounding but i dont like the quality of the headband adjustment. Mine made nasty clicking sounds on one side (not the mechanism itself, the part where it should be attached and not move moved a little causing noise and made me think that it will brake there someday) and the part that slides in the headband seems to be a little weak. I got marks/scratches on mine at the sizes i set them.
I sent them back mostly because of that issue with the cracking mechanism. Sound was fine. I would go for Momentum/Urbanite now.

kuzami's picture

Urbanite>Momentum for me, if you don't mind the slightly bass-heavy sound.

NADscratch's picture

i own the hp50 and i personally really like it. the sound is really great. i do have to say that i have dropped it 5-10 times and (accidentally) tugged the chord out roughly a bunch of times. i am pretty sure the cable is damaged, but i haven't tested it yet. it comes with two cables, one with in line volume rocker/mic, one without, so i could easily test it. i assume this because sometimes when i'm listening with it on my bike everything moves around and i get crackling noises/silence for brief moments.

i'm sure if you don't beat it up like i did you'll be fine though.

the Momentum is available in most stores that sell headphones, you should be able to test it.

also, of course everything comes down to personal preference, but i hate the way the Momentum looks.

castleofargh's picture

the video has some nasty noise, don't know what caused it, but I hope you find out before doing the next one ;)
appart from that, nice reading thank you.

Tyll Hertsens's picture
Yeah, I know. It's actually a known bug in my Canon 7D audio...a friggen $1500 camera. We'll just have to live with it 'til I can budget for a new camera. I'm working on it.
SkylarGray's picture

Tyll, have you tried the Magic Lantern firmware?

You may be able to resolve the audio issues with it. I think you would also hear huge improvements by adding an external shotgun mic or a lav mic. Less expensive than a new camera.

You should be able to get great video on a 7D...but it needs some help beyond its stock config.

Tyll Hertsens's picture
Tried an external mic, but it didn't work. That's when I did some on-line research and found the problem is a deep bug in the update to fix it as yet.
SkylarGray's picture

Okay, that sucks. Have you tried the ML firmware and playing with the gain?

pieman3141's picture

It's usually not recommended to plug in a mic into a camera. You can instead use a shotgun-ish mic (Rode is the cheap go-to option), point it at chest level, and use an external recording device like the H4N to get better sound. A lavalier mic will help greatly too, especially with knocking off environmental sounds.

Lawk's picture

Interesting cans! Don't own open headphones. Would still like to see new Philips A5 Pro DJ.

Side note: the frequency response graph says ATH-M50 vs M50X instead of Philips X1 vs X2. The graph seems to be right, I doubt M50X has such a bass drop off :P

avens's picture

Would you say this is the best low (more like regular) impedance headphone on the market?

mikeaj's picture

Tyll, if you run a sweep from 5 - 10 kHz, does it in your estimation sound like a notch, or are you finding yourself agreeing that the level sounds about right? Or at least, more right than the X1. Maybe the correct level is in between the two, but if so, I guess it's usually better to have a notch than a peak.

Also, I can't help but notice that the Oppo PM-1 and PM-2 have a notch in the same part of the treble. These are also said to be tuned by ear. Coincidence...? Don't think so. Probably. Maybe?

Jay_WJ's picture

You nailed it.

Tyll Hertsens's picture
Maybe. I think I heard it, but notches are notoriously difficult to hear reliably due to all the resonances in the cans. Differences between my personal ears and the dummy head and small placement differences make it troublesome. But again, I did think I heard a softening there.
Jay_WJ's picture

Measurements do not lie. I do not agree that these measure worse than X1. I can immediately see the X2 WILL sound better to me than the X1. Both follow existing target curves relatively well whether the target is DF or OW, perhaps better the OW. BUT except the high-freq peak, X2's response at 5 kHz - 8 kHz is lower than X1. This is a critical band in my experience that makes perceived sound fatiguing if accentuated above the target curve. X1's curve is exactly like that. I would choose X2 over X1 any day ONLY by measurements.

Visigoth's picture

Tyll, how would this compare to the Sony MDR-MA900? Does the Philips X2 sound superior to that particular headphone?

Tyll Hertsens's picture
Sorry, Haben't heard it.
Claritas's picture

It's so funny how coa and I noticed that.

X2 could be interesting though--with mods.

tony's picture

You must've adjusted your color balance a bit , still on 720p though , your colors have a nice darker contrast , voice still sounds like the mic is in a toilet paper tube , a tunnel kind of sound with a bit of echo .
The X2 review , welllll , we already have plenty of great transducers yet they keep working to improve on em , for $300 ? , greatness for less $$$ , things keep getting better and better !
And the old timers try to resurrect Vinyl from death ! , oh-dear .
I had access to the HD800 and it's matching 800 Amp at the Detroit Headphone Show , it was lovely , now I see why you love em so . Gonna have to sell-off my HD600 and go with the HD800s , never heard anything that good in my entire life , they're Hospital Grade Opiates , lushly smooth , a $3,500 or more investment . Once a person hears em it's gotta have em and no looking back , they sounded great despite the high noise of the event !!!
Hope you are well received at RMAF , people might be a bit edgy about your ascendancy , at such a young age too , rather new to be a respected Guru and not at all from our Industry's Roots in Tube Analog Audio , welcomed to Important Industrial Design Centers , listened to by Key Design decision makers , mc'ing important Seminars , your own TV Show bit with colorful wardrobe department . On top of all that , you're somewhere in Fly-over country where the Polar Bears chase down stray house pets and a Motorcyclist , oh-my , not even a Harley ! You own the "Wall of Fame" , I've heard it from a number of people . You da Boss not the X2s !!

Hi, I'm not sure why you say the square wave for the X2 looks noisier. Well, visually it "looks" noisier, but analyze it for a minute. It "looks" more like a square wave, since it has more of a square top, and while there are some ups and downs, if you look closely they seem to be actually lower in amplitude than in the X1. Visually, the broad ripples of the X1 wave "look" smoother than the tight zig-zags of the X2, but they're not. So your hearing is correct, and the measurements reflect it, I think.

DrForBin's picture


AKG fanboi here.

how do these compare to the K712 PRO.

Impulse's picture

I gotta say I didn't expect Philips to have changed much (beyond the pads/cable), but I guess little tweaks can indeed go a long way.

I didn't think you'd end up gushing so much about them either, I almost jumped on the X1 recently (since they're back down to $220) but I'm glad I held off for this review.

I'm pretty excited to try the X2, did Philips actually confirm stateside availability this year? Think I read a rumor saying their US distribution was having issues...

I sure hope not, at $300 or even $350 I'd be all over these the second they're available on Amazon.

Tyll Hertsens's picture
Philips USA told me they're slated for availability in Nov on Amazon at $299.
Impulse's picture

Thanks for the confirmation. I think I'll go ahead and order them right now on Amazon. They aren't in stock yet but they're available to order at $299, I imagine they'll ship whenever they're actually in stock next month.

I'm a little surprised they debuted these at $300, wasn't the price of the X1 higher at launch? Or was that just retailers going over MSRP due to demand? I remember the X1 were available for months in Europe before they showed up in the US.

I believe I read the sale of Philips' headphone/audio division to Funai didn't actually go thru, did that ever come up while talking with the reps and engineers you had contact with? I'm just curious here.

Elmariachi43's picture

Hey ive been using the hd600 through a RSA sr-71b with balanced cable. Do you think i would get better results from the x2 then The hd600 with balanced output? Thanks!

markus's picture

"... there is not a pressure magnitude/frequency dummy head measurement curve that fits all headphone architectures that is a perfect target to satisfy all."
Well that's why a parametric EQ is a MUST for everyone!! Kill your ear canal resonances. It makes listening by headphones so much nicer.

maricius's picture

Great review Tyll!!

Just when I thought I was getting the hang of reading headphone measurements… back to learning.

Also, when, if you are still going to, will you post the review for the Philips Fidelio L2? I'm very keen in hearing your opinion of them seeing that Jude and the guys at Headfonia have them in high regards, not to mention you also previously mentioned that they sounded quite a bit better than they measured.


valissax's picture

me too, please!!

alexnishi's picture

Hey there Tyll!

You said that the X2 has a tighter bass than the HD600. How would you compare the X2 to the HD650, which people claim to have a better bass response than the HD600?

Keep up the good work! You are a benchmark in this sweet i new hobby of mine.

Thank you!

Tyll Hertsens's picture
I think the X2 bests the HD650 bass. It's a little more emphasized down low where it should be, the HD 650 really doesn't have any low bass emphasis.
muad's picture

Hey Tyll,

I am just about to preorder these as a replacement for my hd650, which I consider almost perfect if it weren't for the lack of bass. I was just wondering if the 10khz peak is causing sibilance.


alexnishi's picture

What is your setup sibilance? The HD650 aren't basshead phones, but aren't supposed to be lacking there either.

muad's picture

No, that's why i said they lack of bass. They roll off and thus have a lack of perceived low bass. Everything i have tried as replacements have sibilance. He500, k712 etc. The x2 have a spike at 10khz same as the aforementioned cans.

Tyll Hertsens's picture
Maybe a little. The X2 seems slightly to edgy to me...but just slightly.
muad's picture

Ok, I am going to take a chance on these. Was disappointed with the he500 and K712 sibilance. Fingers crossed...

forkboy1965's picture

Thought you may want to fix such for posterity...

"slightly withdrawn do to the bass and mid-treble emphasis".... we need a "due" here.

Otherwise... very glad to read there is so much work being done on subjective listening tests. No doubt measurements offer a good starting place, but I wouldn't dream of buying anything like headphones without first listening to them and for as much time as a salesperson will give me!

Tyll Hertsens's picture
bronson's picture

"but in the end, it's what the ear hears that counts" amen to that for sure.

I've the X1 and love em - serious amount of HP for your monies - possible the best value open bk available currently?

Great to see Phillips pushing their envelope to bigger and better but for me, I'm going to pass on the X2 in hope of Phillips really going for a big win with something very special as you suggest - something extraordinary in the $600 - $1000 price bracket. I think there's definitely a baying market for such, just look at the fervour surrounding the SONY Z7 for that validation.

Thanks for this review and your YT one too on this new offering from Phillips.

ps nice shirt ;)

kuzami's picture

Hey Tyll, first I wanna say that I enjoy your reviews. Keep up the good work! Now, to my question. I am an electronic music producer, and I have been looking for a comfortable pair to use in the studio (composing, mixing and mastering, the latter two as a reference to my studio monitor speakers) as well as some home listening. I have been looking at the Focal Pro, but I don't think I could wear them for more than an hour straight. So, finally, my question: do you think these headphones will be suitable for my needs?

Tyll Hertsens's picture
As long as you can deal with an open headphone, sure. If you need sealed cans, I'd have a look at the NAD VISO HP50.
kuzami's picture

Okay, thanks :) I can definetely deal with open cans, I don't plan to use them in noisy enviroments, for that i have my V-Moda M100's.

Three Toes of Fury's picture

Thanks dude for another outstanding write up. I love how you have incorporated items and discussion points from the recent threads around headphone profiling (data vs human eval vs mixture of both). I also appreciate your sharing the Philips engineers comments...the details around dummy-head measurement systems is helping me understand more about the challenges of effective data-driven measurement systems.

Quick question: is it safe to assume that the X2's will be easily driven by a portable player? I think you mention they are 35 Ohm. If so i think thats a pretty impressive accomplishment as you compare them to the HD600s (300Ohm)...thou the open cans are really not ideal for on-the-go use. hrmm. Hopefully this sound improvement continues for their closed and semi-closed lines (L2?..and maybe M2 if they make one?)

Peace .n. Living in Stereo


Tyll Hertsens's picture
They're pretty sensitive, and play plenty loud on my phone.
neo's picture

Great review Tyll!! What would you personally choose between the philips or an hd600/650 driven by an OTL amp such as the crack or woo wa6?

Tyll Hertsens's picture
With an equivalently good and properly matched amp I think I'd take the X2...but it's probably more about what you're looking for. While I really like the laid-back sound of a Crack and HD 600, I think the X2 gets things a bit more tonally correct.
balkanguy's picture

There R 3 main factors in good headphone design:
1) Sounds good with EVERYTHING (no 'fatiguing colorations'). This requires a smooth, descenting (from lows 2 highs) EQ curve.
2) Goes LOUD without distorting or changing sound 'signature' (mostly a factor of mechanical design like voice coil length &/or magnetic field uniformity)
3) Is EFFICIENT = goes really LOUD with power output available on N E typical cheap device, such as an average computer's headphone output.

Lastly, keeping in mind that many people have SIGNIFICANT hearing damage is important, because those people will tolerate just about N E piece of harsh, shrill, unbalanced 'balanced armature' krap in existence =)) I liken BA types 2 fans of metal dome tweeters or midrange drivers. They ALL sound absolute krap, VERY distorted-sounding, mainly from the odd breakup in the decay pattern. Doesn't matter if they can make a fancy square wave. They SOUND like trash. When designing 4 real human beings instead of fans of nails-on-blackboard madness, smooth is the way 2 go. EVERYBODY likes Koss Porta Pro phones. They have flaws = kinda' muddy, but 'nice with everything' pretty much. People can always add highs & roll off lows with EQ if they want. The SMOOTHNESS is the most important thing, & Y Koss PURPOSELY KILLS the performance of their cheaper Porta-Pro variants like the over-ears by using metalized drivers 2 fuk up the sound, much like Gib$on guitars will cripple it's lower end products just 2 separate the market & keep the 'people buying the price' in their pens. Don't B a sucker. IGNORE price. It has absolutely NOTHING 2 do with sound quality in the headphone market. This is a GOOD thing, because the Koss KEB15i, with a bit of redesign, is the best headphone on Earth & only costs about eight dollars now =))

Seth195208's picture're acting a totally MANIC, I will take your WORD and purchase the BPOE. They better B GOOD, DAMMIT!

exsomnis's picture

Hi Tyll, thanks for the great review, it's as detailed and informative as always.

Sorry if I've missed it but what amp did you do your critical listening on? I've actually done a quick audition with the X2s before this and while I did hear some hifi-ness in the mids to highs, on my iPhone the bass was so severely pronounced as to be unbearable.

Tyll Hertsens's picture
I listened to them on my Samsung Galaxy S3 phone, A&K120, HeadRoom Max, and AURALiC DAC and Amp.

I think a properly emphasized bass does take a little getting used to (like any sound). I find I prefer that Harman low frequency boost after hearing it on a number of headphones (NAD VISO HOP50, Focal Spirit Pro, Shure SRH1530, ext).

SevenPlus's picture

How good did they sound on the S3? Are these good headphones to be used just with a mobile device for listening mostly EDM, or would you suggest something different (X1, ATH-M50x etc)? (I will be listening at home, don't need any isolation)

In the X1 review you mentioned that the X1 is "a really great headphone for EDM". Are the X2 "even greater" in this regard (EDM)?


Tyll Hertsens's picture
One note of caution here: I'm not a big fan of EDM or a cultural fit into the scene, so my esthetic values may make it impossible to answer you with is all subjective, you know. Frankly, I'd think most EDM listeners would prefer sealed cans that can do a better job of achieving sub-bass than open headphones. The real advantage of the X2 for many will be their excellent imaging...or maybe sense of space is a better word. The bass is damned good though on the X2, and I'm sure it will satisfy many folks wanting a better sense of thump than they get with measured flat bass response cans.

RPGWiZaRD's picture

Any chance you could have a look at the new Philips A3-PRO and A5-PRO sometimes? :) I've seen frequency response measurement on head-fi and it looks pretty good.

RPGWiZaRD's picture

And the headphone itself is nice, especially A5 accessory-wise with 3 choices of pads made for it and the headphone looks like built like a tank, yet looks very nice at the same time. Probably a headphone which can replace V-Moda M100 in WOF.

bronson's picture

Hey RPGWiZaRD, so ULTRASONE Sig DJ's not besting the Q40's for you bro?

I own & enjoy the A5Pro and agree that continuing the Phillips flow would be interesting to hear Tyll's impressions of the Armin Van Buuren collaborated A5Pro offering.

Not sure if A5Pro will do it for you though as it doesn't have the kind of bass centric sound signature of the Q40 or that matter the Sig DJ's. I find the A5Pro far more nearer to neutral sounding in the bass dept.

RPGWiZaRD's picture

Yea, I ended up now going back to Q40 and probably will put up Signature DJs for sale sometimes soon. They did provide technical improvements, especially in terms of soundstaging and airiness. But for my taste the Sig DJs were slightly too bright / mids slightly too recessed. I'm looking for a fullbodied, up-front and bassy (punchy) sound. The Sig DJs got very close with the added foam I put in the cups to balance out the mids/highs but the comfort/fit issues and the fact that Q40 seems to entertain me just as much and possibly slightly more (works better with badly mastered music), decided it for me.

I'm personally looking for the "punch" characteristics in bass, the digiZoid ZO amp can boost the bass pretty nicely. You know the kind of invisible sound like standing near a "drumset" and feeling that impact of every drum hit. Both Q40 and Sig DJs do that well.

sszorin's picture

What is your PERCEIVED volume drop of the middle frequencies ? Are the mids of X2 mildly or moderately recessed ?

MarkThompson's picture

I've actually been quite happy with my Philips Fidelio X1, think I might get the X2 too :)

Though I have to say they are a bit too tight in my opinion, or maybe it's just that my head is too big, not sure.

Spy's picture

Hey Tyll, thanks for another great review.

How would you compare the sound experience of the Philips X2 vs NAD HP50 ?

Which headphones do you prefer to listen to (let's assume in a quiet enviroment where sound isolation doesn't matter).

ar's picture

I'm not Tyll, but I much prefer the X2 sound to HP50. Though I put a ton more hours into listening to X2.

Go somewhere where they would have both... though I failed to find a place that would have both - it's been a while.

Dizzy's picture

My thoughts on both of these: Overall, Fidelio X2 are the better headphones for detail, soundstage, and musicality. They are, however, ever so slightly coloured in their presentation. They're also less neutral with a bit more bass emphasis.

In comparison, HP50s are very neutral, very uncoloured. The HP50s do nothing wrong, but nothing wows you either. They do it all well in a very fatigue-free package that is also portable, closed, and easy to drive. They're fatigue-free because they're just pulled back a little on mids and trebles, ever so slightly veiled, if you wish. It's exactly what you want if you want headphones for work, because they are so fatigue-free and because they still sound good at quiet volumes.

HP50s are great for commuting and work and only a small step down from the X2s. I'll choose the X2s at home any day of the week however because you just enjoy every song with them. They make me enjoy music that I thought I didn't like.

They're also direct opposites in build: The HP50s are compact, light, and plasticky, whereas the X2s are huge, solid, bulky metal things that would make you look like a fool in public.

Neither is bad. Both outdo both my Bose QC25s and my old Sennheiser HD595s.

Mad Lust Envy's picture

Tyll tends to have very, very similar tastes to mine (nowadays), and his compensated graphs is among the best at giving a very good idea on a headphone's sound (it hasn't let me down yet).

Looks like the X2 is my next headphone. That detachable cable (I like to add a V-moda BoomPro mic cable for gaming), the fact that it's open, not pleather/leather padded, and warmish bass sold me.

I really liked the X1, but it's fit wasn't perfect, and the bass was a bit too loose. Looks like they fixed the two biggest issues I had with the X1. I also like that they attenuated the 5khz-9khz range, as that is definitely among the worst areas in sound to have even moderately emphasized. If any treble range deserves a peak, it's 10khz, not anything before that.

I think the X2 is going to be a HUGE win for Philips.

DaveinSM's picture

Great to see that they fixed all the issues with the X1. Maybe it's the skeptic in me, but the alignment pin and hole in the new replaceable ear pads are to ensure that we have to buy the replacement pads from Philips and not an aftermarket 3rd party pad maker.

lr99gt's picture

Hi Tyll,

Long time reader and this thread finally made me decide to post. I have already purchased the NAD HP50 based on your recommendation and have really been enjoying them. Previous to that I had a D 1001 Denon which recently broke so I am looking for another set. I have narrowed my search down to these 3 and would like your advice since I cannot audition these myself:

Philips X2 ( Do you prefer this to the NAD HP50? )
Oppo PM2 ( is it worth the price jump over the x2? )
Pandora Final VI ( have you had a listen to these? Reviews sound interesting )

I realize the last is sealed which doesn't make or break it for me. Comfort and sound quality are important. I would like something with a slight bass boost. I also want something that can be amped with my AQDF since I use it from my laptop mostly.

Any advice is appreciated!

Thanks Tyll!

DiRo's picture

Hi, These X2 seems like a great value considered comparable for 1/4 less. Was reading though the comments unless I messed it was wondering how these compare to the HE-400 now HiFiMan have dropped them to exact same price at $299? Thanks

Jazz1's picture

Thank for the review. I'll have the X2's on my hot little ears this Sat. Great way to enjoy Thanksgiving weekend. They are going to sit right next to my HD-650's.

macauley86's picture

Has anyone had the chance to compare the Fidelio X2 and the Sennheiser HD 598 for both music reproduction and comfort over extended stretches of time?
Thank you

Jazz1's picture

New headphone fever here! I'm sure it is probably too soon to give them my best opinion. But, I have to say they are very comfortable, and the self-adjusting feature of the leather headband strap is much appreciated.

My ears fit nicely cushioned ear pads. I'm still going to give a slight edge on comfort to the HD650's, but I think these will loosen up on the clamping force and may equal them over time. But the clamping force of the X2 does not bother me. You don't want them falling off your head while grooving to the excellent sound.

They are lighter than I imagined when hefting them in my hands. But the HD650's feel lighter on my head. Not a complaint. I also own the Blue Mo-fi's and nothing in my collections is going to feel heavy compared to them.

Build and hardware quality are good, not great. Not even close to my B&W P7. I see a little white/silver metal or glue showing through where the headphone ring hits the speaker housing. This is a little disappointing as the marketing pictures gave them a Porsche persona. Also the Blue Mo-Fi's "industrial" metal beats these for an extra $50.00. that said the X2's aren't going to fall apart when compared to the build of the aforementioned headphones.

When you think about it, it is amazing what an extra $100.00 can get you with the P7. The leather is of higher quality on the P7. I know leather as I used to work in a shoe factory many years ago (Frye Boots anyone?) However, none of this ultimately detracts from the great sound of the X2. So I won't bring them to the Gentleman's smoking and single malt club ;) So don't chastise me for appreciating materials and quality control. The X2's may become my favorite based on sound alone.

Using my desktop rig at the moment. PS Audio GCHA and Musical Fidelity M1 DAC fed AIFF files from my iMac. I'll try my IOS devices later this afternoon.

Let me just say that Jackson Browne sounds great on these. Listening to "Running On Empty" and "You Love The Thunder" are bringing me back to Jackson's 70"s concert in Iowa City, IA sans the burning leaves smell ;) Los Lobos' "The Road to Gila Bend" has very rich guitar and the drums sound great, all without drowning out the vocals. Little Village's "Inside Job" sounds rich and balanced.These headphones really entertain!

These sound great driven only by my iPhone 6. The guitars on Greg Caquico and Russ Freeman's "From the Redwoods" blew me away. Sonny Landreth's work also surprised me.The drum beats on Chrisette Michele's "Blame it on Me" made me look down to make sure I hadn't plugged into my desktop rig. I don't think I've heard better sound from any of my IOS devices.

Tyll your review is right on. Now I finally own one of the "Wall of Fame" headphones. Thanks!

i dont understand the freq response here on your tests because recording to your tests the focal pro have much more sub bass and bass than fidelio x2 or x1 and you say that focal pro is very very neutral ?? than u say that x1 /x2 have more bass than q701 ,but in your test the q701 is far superior in sub bass than x1 or x2...damn, i miss something or what ? thanks

Tyll how are you. I hope you are great. Very nice review.

Thank you!

Hi Tyll, Thank you for your great analysis of the Fidelio X2! I love my X2s, but unfortunately have come across a physical issue with them - The hex-bolt attachments at the base of the headband are starting to come loose - they look like they can be tightened, but disassembly looks a bit tricky. Might you have any access to resources available (assembly drawings, insight, etc...) for assisting in self-servicing these bad boys? Shot in the dark here, but figured your place held some hope with at least a point in the right direction to tackle this issue. I also have high-mag photos of this issue exposed if you're interested. Thank you!

I found out about these headphones by reading a review on Amazon. It made me laugh out loud so I googled more information and found this site:

Now I know everything needed to purchase this product. Thank you to the great reviewer on Amazon and Mr Tyll also.

Mr Tyll your review is wonderful and very in depth.

Thank you.

The X2 sounds like a phenomenal midrange open headphone. I have closed midrange cans that I really like (NAD Vido HP50's) but I'm wondering Tyll if you think it would be worth it to invest in an open pair for home use. (I primarily use the HP50's at work - I have a very desk-oriented desk job, if you know what I mean.)

Perhaps you could do a short article doing a comparison of open and closed designs at different price levels and for different use cases? That would be useful!

Hi Tyll, hi Everyone :) Thank You for Being :)
I have the CAL! for ca. 8 years - and I love them until today. One year ego I bought the CAL!2, because many reviews were like: "the CAL!2 are better than the CAL!" or "CAL!2 are a worthy successor". But I send them away... too much low frequency (for me), and not so natural sounding like the CAL!.
Then I read Your review "Like a Boss". I bought the X2. And... I don't know... (I compared them ca. 20h – rock, metal, blues, jazz, pop, electronic, reggae, rap, …). Reason ? Maybe it’s out of habit, or maybe it’s because my music source ? (I’ve got only a mp3-player: Sansa Clip+, but in my opinion it’s a good one).
Some suggestions ? Tyll ? Anyone ? :)
Thank You for any answer :)

own a Zune 120 and I use the Zune Pass music subscription with it. To my knowledge, there is no way to get a portable amp to work with this Zune. Because of that, I am limited to low impedance headphones. I am currently using the Grado SR-60i, which I consider to be about the best portable headphone (but definitely still just an "entry" headphone [as opposed to mid-fi or summit]). But I was recently introduced to the Philips Fidelio X2 headphone, and it seems to generally compete with the Sennheiser HD 600, which is recognized as about the best mid-fi 'phone. The Philips Fidelio X2 is low impedance (30 ohm) and supposedly sounds decent un-amped with portable players.

My questions are these.

Is this the only low-impedance (un-amped, portable decent), mid-fi headphone in existence? If not, what are the names of the other headphones?

My Zune 120 files are 196 kbps WMA quality. Is the Fidelio X2 too high quality to make files of this quality sound good?

Is the Philips Fidelio X2 a HUGE upgrade in SQ (highly noticeable to the common hearing man) over my Grado SR-60i? After all, the Fidelio X2 ($300) does cost quite a bit more than my Grado headphones ($80).

Thanks, Tyll!

I'll be VERY grateful if you reply!

The first sentence is supposed to say, "own a Zune 120 and I use the Zune Pass music subscription with it." The 'I' must have gotten cut off somehow.

There seems to be a problem with the pads on X2.

Lots of YT videos of people leaving the X2 on paper and coming back to a purple ink stains in a few min.

I had my X2 swapped because of this. Was hoping it was a "bacth run" issue of that they would have fixed a problem, but it's back.

Tyll, they clearly aren't listening to end users. Could you hit up your connections at Philips? Such an amazing product. Such a small flaw. Would be a shame if that wasn't fixed.

Happy to provide more feedback, to get this fixed.

Hello Tyll, might I ask if you have heard any good news re. the Fidelio X2 challenges? I follow your great programs from overseas. A friend asked my opinion on these, but with all the negativity....

May I elaborate for a moment?

Ok, to start. Not everyone can purchase their goods at Amazon. Not all have got the time nor the financial means to - I'm paraphrasing here - buy at least five or six pairs of phones before arriving at ends journey. Heck, I won't live that long.

My concern with the Philips Gibson X2 package is that pads seem to be glued as standard issue globally rather than a once-off run gone bad. I wanted to buy them. I wanted to recommend them and I still do...sort of.

This reduces in my opinion the life span of the product. More, having contacted support division at Philips here in Europe, they demand that these phones were not detachable, never have been, never been a problem solved from the X1 era etc.

In Norway as products carry 3-5 yr warranty periods with full new product replacements or service to equal standard. But to what standard? When confronted, Philips claim " the gluing of the pads is a feature rather than a hick-up, the inking must have been once-off and that "it is mainly an American concern, dealing with typical U.S. reselling not common in Europe."" Horse manure, I say!

Sales support went so far as a total deniability of the existence of detachables at any time on the X2. Now, I happen to come across your excellent 2014 "pads detached" photo and after having viewed you review of the, at the time, new X2, I need to ask if you had a retail sample or an early version? Detachable pads are honorably mentioned on the original retail box, marketing material in the store, but sales rep doesn't want to break the seal.

Albeit, we have sturdy warranty policies, store returns are HIGHLY frowned upon. So this is actually quite important. There is no grace period. Also, I have lost track of the number of pads I have replaced on my now decade-old Sennheisers, extending the lifespan. Silly me, I actually entertained the idea of swapping them out for these X2 beauties. I still hope I can, but I don't want to invest in a company who only wants to shortchange me in return.

What is true and what is not? Have you guys heard anything of an X2 v2 or an X3 anytime soon?

Avid fan of InnerFidelity in Norway.

Philips posted an official statement concerning X2 issues on their support forums early this year.

- Ear cushions are fixed by glue in individual batches:
In an attempt to improve the manufacturing process, glue was added to the pins which support the Philips Fidelio X2 headphone’s removable cushions. Acoustic testing showed that this did not impact sound quality, however this modification proved excessive leading to some cushions not being detachable from the headphones in individual cases. For that reason, it has since been removed from the production process.

Maybe you should send the person at Philips who claims the pads should never have been removable that link...

Where in Norway? So good to know I'm not the only one. I recently bought these from Elkjøp for about 100$ and what a bargain! You won't find a better product for that price. Btw, the pads on mine are detachable. I tried.
