I got my set today.
They're great. Comfortable, fairly isolating, nice soundstage...
Except mine has unusually high impedence. I have to drive it extra hard to get a proper sound out of it; my Sennheiser HD 280 PROs and Urbanite XLs are at "comfortable listening levels" at 40% volume, but these have to be pushed all the way up to 60%.
The reason being...is that there is an electrical short in the headband.
I need to find my voltmeter to "prove" it, but you can FEEL the electricity passing through your fingers if you touch the center of the headband while it's being driven, and you can hear a ground loop hum in the cups as you run your fingers over the surface.
I wish I could record it. It's bizzare.
But, as long as I don't sit there running my fingers along the headband while I'm using them, it'll be fine.

Halfingrit'd probably be best to exchange for another pair while you still can. No sense in keeping a a defective pair even if it is barely working.

EinTheVarianceOh, I know. Gotta enjoy them for a day, though. They still sound great.

HalfingrIf there was a short, wouldn't one of the cups stop working completely? Due to the drivers having more impedance than a dead short

siidheeshLike I said, it's bizarre, but you can hear the ground loop in the right ear a LOT more than in the left one; it's obviously a problem with the cable passing through the headband. I just don't have a good head-shaped microphone assembly (and I can't find my voltmeter) to prove it with.
Again with the weirdness, the headphones are pretty balanced, and they sound great, despite the obvious problem.
