Last week, when I posted about AKG K1000 measurements, many readers were perplexed about the apparent low frequency isolation with what ought to be about the most open headphone you could possibly have. How in the world could it be providing any isolation at all, much less in the low frequencies that are particularly had to shut out?

Frankly, I thought I must have just done something stupid and there was something wrong with the measurements (though I did double-check at the time). So, I remeasured again this weekend...and basically got the same result!

Sometimes my job is quite humbling. Like when headphone enthusiast yaluen decided to ship me a dozen headphones—many very rare and collectable—from his collection for measurement.

We're in for a real treat this week. Head-Fi member yaluen has most graciously shipped a treasure trove of vintage headphones for me to measure and share with InnerFidelity readers. We'll get to the sweet cache of Stax cans in short order, but I figured I'd offer up this sweet set of measurements as an appetizer.

You never know what kind of rabbit hole you might fall into on a scrounge through the news feeds. Turns out, according to research from the University of Caen and the University of Strasbourg, both in France, that you can reduce stress in horses during trailering and farrier work (horse shoeing) by letting them hear music. Tests were conducted with 48 horses at various time using horse headphones, ear plugs, and with no apparatus as a control. Stress was monitored in various ways including heart rate. Results showed reduced stress and better recovery from stress was achieved with the use of horse headphones and music.

Research says we hear the beat in the bass, and, in another paper, we hear the melody in the highest note. Moreover—and this is the surprising bit—these perceptions appear to occur very early in the peripheral perception process well before we cognitively appreciate the music.

After determining the JBL Everest Elite 700 was good enough to poke it's way onto the Wall of Fame, I came to realize I wasn't certain where to put it. Should it be on the Wireless page? Or should it be on the Noise Canceling page? Or both?

After my CES experience with Ossic, Dirac, Sennheiser AMBEO Smart Surround, and the AKG N90Q, I've begun to spend a little time rooting around for potentially interesting headphones and requesting samples for further investigation.

There's just no question.

Four years in the making, this all-new Beryllium dome driver headphone design from Focal has completely disrupted the flagship headphone category. The Utopia ($3999) is the best headphone I've ever heard...by a significant margin.

You all knew in your heart MP3 compression was bad, right?

Why yes, yes you did!

Surfing through my headphone news feed the other day I stumbled across an article on Picky Ear titled, "Best Headphone Brands: What We Can Learn from 310,067 Headphone Reviews." After reading through their conclusions I learned that aggregating thousands of reviews, no doubt largely populated by folks who really don't know what they're talking about, generally nets you a fairly random result. Maybe I shouldn't pick on Picky Ear; I've seen lots of these lists and have a hard time taking any of them seriously.

Here's my list.

I'm in the process of writing a survey of headphone manufacturers and their worth in the world, and find myself repeatedly asking the question of who will carry the banner for high quality sound reproduction in the future. Consumers will claim sound quality is important, but, in fact, it plays a lesser roll in actual purchase with styling, comfort, and build quality leading the way in consumer decisions.

Which of the following major headphone producers do you think will do the most to promote sound quality to consumers at large as important...and deliver on that promise?

I'd love to hear the reasons for your pick in the comments below!

Which headphone maker will be most influential in promoting sound quality as an important performance characteristic?

Many of you will be aware that I've had some trouble with distortion measurements lately. Well, fortunately it had gotten so bad and consistent that I was able to identify a repeatable problem and trouble shoot the system. Turned out to be a combination of a noisy power supply in the headphone amp I use, and a corroded power connecter to the mic pre-amp. I switched out the headphone amp and bought a small motorcycle battery to power up the mic pre-amp and BOOM! the problem is gone! Phew. So I went back and did some re-measuring of what headphones I still had here, and measured a few that were laying in wait. Good times.

Headphone commercials are pretty rare. National advertising is expensive and not many headphone companies can afford that kind of dough...well, one can.
