Here's a brave adventure: Bring an entire line of headphones retailing below $100 each to a high-end audio show. 1More is a San Diego based company specializing in affordable headphones. I've measured some of their previous IEM models and they were pretty good at the price points. But the line is largely refreshed and after a listen at T.H.E. Show I'm convinced another round of listening and measurement is in order.

In the years since I've had the opportunity to chat with Richard numerous times. I'm really not a fan of bullshit, blowhards, and artifice...which is to say, I really enjoyed my times with Richard. He was about as cuddly as bag of razor blades, but he was the no shit real deal. A rich/complex/imperfect human doing his double-damned best working with others to make our industry work, and trying to deliver a good time as well...because if you're not having fun while you work then why bother?

I missed him a great deal this year.

Sweet! Had a great day at Harman yesterday with Warren TenBrook (his conversation with Sean Olive here) and the Harman engineers. Two series of measurements were made, one with both speaker channels being driven, and one with only the left speaker driven. Fifteen measurements were made for each series at +/-20 degrees, +/-10 degrees, and 0 degrees azimuth at elevations +/-10 and 0 degrees.

Thursday I will be at Harman's research laboratories to measure what my head hears when in front of a very highly calibrated speaker system. It's an effort to drill into the measurements and, slowly but surely, come to a better understanding of what's going on.

Lest you think I'm being a smarty pants with the headline, it was a direct quote from John Morrison, President Audio-Video Club of Atlanta, when I complemented him on producing, what I feel, a virtually ideal regional headphone meet. But I'm getting ahead of myself...

One of the things that, it seems to me, separates headphone enthusiasts from traditional audiophiles is an interest in good inexpensive stuff, or devices with unusual utility. Think Koss Porta Pros or the Riva Turbo X. The Porta Pro has been delivering excellent sound quality for its very low $49 price for decades and for decades headphone enthusiasts have been praising their worth. And when the Riva Turbo X Bluetooth speaker showed up at CanJam a year or so ago, headphone hobbyists embraced it immediately as a great sounding portable speaker. These are cool little gadgets, and it seems to me headphone enthusiasts are more than willing to have a good hard look at them....no matter the cost.

Not long ago, I wrote a little article documenting the effects of different filters in a headphone. Soon thereafter, one of the headphone engineers at Skullcandy shot me an email pointing out a company that makes acoustic filter materials for industry. Boy, wouldn't it be nice to get past the toilet paper and get some of the real deal into the hands of hobbyists. So, I followed the rabbit down the hole.

In this article, we're primarily going to discuss the dynamic nature of the headphone driver as an electrical load on the amplifier driving it, which is expressed as impedance and is essentially additive to the resistance of the voice coil. Impedance is somewhat like resistance in that it can be expressed in Ohms, but it's quite different in that it is "reactive" and the impedance in Ohms can change depending on the frequency applied.

It's been a long time...too long...since I had a visit with my Southern headphone enthusiast brethren and the Audio-Video Club of Atlanta. It was maybe 8 years ago since last I shared a meal with Chuck Bruce and John Morrison, but the ham, grits, and red eye gravy was unforgettable!

Woot! Imma do it again next week!

First, how in the hell do you make a pair of headphones, distribute it to retailers, and have it shipped overnight to your house for $20!? I shake my head; how can this be? Well, the answer, of course, is economies of scale. And with 312,000,000 headphones sold world-wide annually, there's plenty of scale in that economy.
