The Incisive Audio Technica ATH-MSR7 Measurements

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

Looking at the raw frequency response plots we can see that the MSR7 is relatively insensitive to positional changes on the head. A fairly broad hump in the bass and mids does good job of approximating flat, but clearly has an overall tilt that diminishes the bass and cools the overall response in that area.

The rise to the treble peak starts at 500Hz, goes up 10dB by 2kHz then remains flat to 5kHz. The problem is it rises too fast relative to the target response and causes a rise in the upper-mids and low treble. The broad peak between 2kHz and 5kHz is actually about 2dB lower than the target response, and the subsequent dip between 6kHz and 8kHz has been used in other cans to reduce harshness. Energy at 10kHz may be a tad high, but about right thereafter.

The sway-back on the 30Hz square wave relates to the long hump mid-range and below, and the fact the it starts immediately with no "shoulder" at the beginning of the wave shape is a clear indicator these are treble tilted headphones.

The initial spike of the 300Hz square wave is not excessively high, which indicates the high treble is not excessive, and the fact that it's so clear in shape with very little subsequent noise means that the transient response and resolving power will be very good. Likewise, the impulse response is quite good, showing rapidly reducing noise after the initial spike.

Distortion is stunningly low! The 100dB curve is below the 90dB curve for the most part indicating the headphones should have good power handling. A very slight rise in the bass shows an inkling of misbehavior, but it's still much lower bass distortion than average for this type of headphone.

Impedance plot shows a nominally 37 Ohm headphone and while it wiggles around a bit in the treble, it's fairy clean indicating good acoustical treatment around the driver.

Isolation is -15dB broad band but in the isolation spectra you can see that it tends to be more high frequency isolations. Below 800Hz there's very little attenuation at all.

With 23mVrms needed to achieve 90dB in the headphone these will be driven to satisfying listening levels by portable devices.

It might be worth mentioning at this point that Audio Technica touts a "Dual-Layer Air-Control Technology" in these headphones. Basically, there are two metal chambers behind driver before venting to the outside which, they claim "reduce unwanted resonance and enhance the texture of the sound". I don't know what these chambers really do, but I can say that given the measurements here they have done something very good in this headphone and should keep after it.

I'd love to see how these compare to the Sony MDR-7520, which also offers a referance level sound quality, and some others think it's bright, albiet I do not, metal cup design with a big pad, etc etc. and it appears we like a similar sound signature. I really think you should try to get a hold of a pair of those. I would send mine in for measurements and a review if you deem them worthy. I much prefered the Sony MDR-7520 over the NAD VISO HP 50, and the other popular wall of fame closed headphones.

Because the NAD and these are at a similar price range, will these be replacing the NADs Tyll?
And also, could you please compare them more? I have both and I personally rather have less treble than the Audio-Technica and I like the bass and mids more on the NADs. Same story with sound-staging especially with the AK240. I felt that the AT had the AT house sound that's typically a bit bright.

That Hi-Res Audio certification is something the Japan Audio Society places on products they deem worthy of it. They have a subjective listen and test the 40hz region of the headphone/iem. Seems kind of gimmicky but I guess it takes some merit to get it.

And wow, the efficiency on these headphones is probably the best I've seen for a full closed back based on your measurements.At 0.023 it's even more efficient than a lot of IEMs.

Mighty tempting to pick these up after reading your review Tyll!

Do you have the DT1350 in your possesion still? They too are considered reference level, What do you make of the MSR7 in comparison wrt overall resolution and 'see-thru' delivery?


DaveK1977's picture

I have the (pre facelift) DT1350, and I love the sound. Comfort isn't their forte, though.

Glad to see you liked these Tyll! I've really enjoyed them so far. I do get a little bit of an issue with the headband causing a hot spot on the top of my skull and I think it can be just a bit too bright to always be used safely outside the house, but otherwise I think the MSR7 is a real champ of a headphone.

I'm looking forward to your take on the M70X, which shares some resemblance to the MSR7, but gets a bit more extreme in some dimensions!

Nice! You managed to change it LOL

Maybe's picture

There's a headphone called RP-HD10E-K from Panasonic which has the same "high-res" certifikation and a similar design to the Sony and the AT.

Diaphragm looks quite funny. Would be interesting to see how that one competes since there seems to be no reputation in the forums whatsoever.

"I do know a good sounding slightly bright headphone when I hear it...and that's exactly what the MSR7 is. Bass is 1 or 2 dB too low in level..."

Or maybe 5 or 10 Db too low in level...

Tyll Hertsens's picture
Well, if you look at the bass level at 40Hz it's still 4dB higher than the dip at 500Hz, which could be considered the baseline. But you're right, I'll change the copy a bit.
Long time listener's picture

No need to change any copy...I was just expressing a personal preference. As you noted, these won't match everyone's taste. I can tell from the measurements they won't match mine, despite looking really good in some respects.

I love them. Lots of good reviews too. They cost $104 @ Amazon.

Luigi's picture

But, if we forget stupid discussion about marketing, sony 7510, hd380, hd280, k545, srh940, and many other ugly headphones are sonically vastly superior to this msr7, in my opinion

BarbecueGamer's picture

Fantastic review Tyll! Say, did you receive the Momentum 2.0 yet? I've decided to wait on your review of them until I consider purchasing them.

zobel's picture

these are in improvement over the original version, especially in fit for people with larger than average ears, and the fact that they fold. I have read at head-fi that the sound is even better!
As much as Tyll liked the original, I would bet he will just love these, but I too will wait for his review before buying them

BarbecueGamer's picture

That's what I've heard as well. I just want to wait and see if Tyll likes them better than the NAD Viso HP50. He holds those in very high regard, as do I.

I'd be very interested in how these compare to the Yamaha MT220, especially as the Yamahas seem to be going for about $100 less these days.

HugoQueiroz's picture

I know, I know it's not a valid comparison, but I really would like your opinion on the matter.
I was about to buy Bose QuietComfort 25, noise cancelling interests me and I plan to use every now and then. I would like to know how the QC 25 compares to the ATH-MSR7 on sound quality alone. Does the ATH-MSR7 is just way ahead of the QC25 or the QC25 can please the none-critic ear?

ina's picture

Tyll, can you please make a glossary in the Resources section on what different terms mean, like imaging, soundstage, dynamics, resolution, transparency, clarity, smoothness and so on?

Would you say this msr7 is a worthwhile upgrade from the Sony MDR 1R, or is there too little improvement in sound quality to spend the money?

For the Shure SRH1540, you say the sound quality falls apart a bit at higher volumes. At how many decibels does it start at? Or up to what volume does quality stay the same?

And what's a cheap, good way to burn in headphones like these on your Wall of Fame? Do you have to run them through a dedicated amp or usb amp stick like the Dragonfly, or is it just as good if you play music continuously for weeks using only your ipod?

What about reviewing the m70x?

sszorin's picture

Long time listener : "Or maybe 5 or 10 Db too low in level..."

Where did you get 5 or 10 dB from ? Looking at the graph the bass end should be lifted by 3dB and that's it - maybe 5 dB at most. A 10db gain would wreck the sound presentation of these headphones.
With a little bit of eq-ing MSR7 can be great headphones. +5dB at 500 Hz and +3dB at 90, 70, 50 and 30 Hz. Or one should get a hybrid portable amp for them. A triode can gently skim off a little bit of treble. and also add a little bit of body to the tones.

50x, 70x and MSR7

The plot and other graphs make it seem like the Yamaha Pro500 and this should sound the same. But one is on the wall of fame and the other is generally disliked (tho I like it). I gotta hear these and decide for myself.

m8o's picture

Should sound similar ... did not mean to type 'same'.

Luigi's picture

the pro 500 are the most underrated headphone in the world. But it seems that yamaha doesn’t pay reviewers so well...

Hi! How do these compare to the Beyerdynamic DT 660?

physics's picture

Thanks for the interesting and informative review on these headphones. I have bought the ATH-M70X and was wondering if you had any info on when we might be able to see a good FR evaluation on these headphones. In the meantime, could I assume that the FR curve of the M70s would be sufficiently close to that of the MSR7s here that I could use that as a good approximation?

steaxauce's picture

For perspective, how do these compare in brightness to AKG's K701/K702/K712 line?

Nomad_Soul's picture

Very nice headphones. Shockingly so for the money. I sold my more expensive SRH1540s in favor of these and have no regrets whatsoever.

Hi all,
I used to own Denon AhD1100. Now I want to buy something good for me and after doing many research it seems that MSR7 has a lot of reputation. However, I am still concerned about this headphone:
I intend to plug MSR7 directly into my Iphone6/Laptop for porability. Does it sound good enough ? Or do I need to buy an amp/and DAC ?
I am currently owning a Schiit Modi DAC (At that time I did not have enough money to buy Magni LoL). If it needs an amp, what is your recommendation for a good budget amp ? (Magni???)

arenberg319's picture

I mean, does a budget amp stacked with my Modi will improve the sq much or it's not worth ???

venki's picture

I find my MSR7 sound quality is dull and no energy. I tried with Oppo, Fiio, creative SB-E5, samsung S6 edge, all shows that flat and dull. compared to other headphones, Demo set in the other shop, the SQ seems pleasing and transparent. I even sent my headphone to service centre, nothing but measurement data which which means everything is perfectly fine according to them. But i feel like missing bunch of frequencies.
I have added the measurement data link here. Does it make sense?
