I'll often unbox a headphone and take a good hard look and listen and then make a guess at the price before looking it up on-line. I'm usually 25% - 33% low...and disappointed at how much things cost. Not so with the Sennheiser HD 4.40 BT, I guessed $50 high at $199. It's $149...sweet.

Having not too long ago reviewed the $1499 AKG N90Q and finding it an astonishingly cool and effective noise canceler, I thought it would be interesting to look at what AKG was doing way down the food chain at a more affordable price. Thing is $300 is still $300, and in my book a pretty serious purchase. A $300 headphone needs to be good and competitive. Let's see if AKG managed to pull it off.

Oh boy. The folks at Massdrop have gone and done it again. Just got their new Massdrop x HiFiMAN HE4XX in for measurements and a quick listen before the drop.

Sennheiser has been "remastering" their line-up for the past little while and I've been itching to get a little ear time on some of the more affordable models. In a marvelous turn of events, they sent me a couple of boxes filled with headphones for me to measure, evaluate, and cherry pick for for good values. Here's the first one...

When first I saw the Audeze iSine models I wondered to myself, "What the heck are these for?" and, "Who will want these?" I'd never heard of an open acoustic in-ear before...heck, I'd not even thought of the possibility. Why in the world was Audeze even going down this road? I spent some time on the phone with Sankar Thiagasamudram, founder and CEO of Audeze, to gain some understanding.

A nice little handful of measurements...find some air conditioning and ice tea and have a look.

There's a lot to like about AudioQuest's NightHawk and NightOwl: great comfort, very low distortion, exceptionally flat impedance response. Unfortunately, I found the NightHawk far too dark for me. AudioQuest goes into great detail to justify the tuning of this headphone on this page. I find the information written there about headphone performance and response characteristics simply outstanding. I sure wish more manufacturers went to that much effort to describe what they're doing.

Oh baby...don't read this if you've got $800 bucks in your wallet and a yen for some good sealed headphones.

Quite the tumult over my Sony MDR-Z1R review. The forums churned. I think I need to re-state where I'm at.

Out on my morning web surf and I stumble onto a bombshell on the front page of Head-Fi:

"Sony MDR-Z1R Measurements: Head-Fi HQ’s compared to InnerFidelity’s"

That article links to a much more comprehensive post in the Z1R thread by Jude Mansilla, Head-Fi's Founder. It seems Jude's measurements are somewhat different than mine, particularly in terms of the peak in response around 10kHz. Here are the two plots in question.....
