Update 8/04: These have been disappointing. My first pair was clearly defective and they were replaced. The second set seemed ok, until I plugged it into a charging iPod. The 60Hz hum was deafening. Even being near electronic devices was a problem -- they picked up a hum. They seemed to have both a grounding and an antenna problem. They work best on airplanes (little interference) but aren't very useful on the ground.
Update 4/28/05: The cord finally broke, and I was free to replace these darned things. They weren't all bad, I got my money's worth I suppose -- but one year is short lifespan. I had been steeling myself, and I bought a pair of Bose II headphones for ... $300 (ouch, ouch, ouch)! The Bose come with a very nice case. They're probably only 3x as good as the Plane Quiets, so they're overpriced, but that's the way it goes.
