i just got a pair of senn 280's last week. i like them, but i'd rather have something more comfortable with a warmer sound, so i figured i'd see if anyone here would want to work something out.
the senns are pretty much brand new. the only use they got was 50hrs of burn-in and a few hours of listening, all at home hooked up to my computer. you'll get them in the original packaging with the manual and 1/4" adapter.
i'll either trade for a pair of beyer 250-80's (c'mon) or sell for $100 with shipping (ups ground, insured). if no one takes me up on either offer in a week, i'll just return them to headroom.
