I use a pair in my office regularly. They are an awesome phone, if you can get past the quirky (bizarre?) looks and ergonomics. They work great with Cary 300 SEI, Cary 2A3i, Audiovalve RKV, and Granite Audio Aspen amps (as well as many others). Very revealing, need good source and amp, but very rewarding. No isolation but most speaker-like sound of all the cans I have use.
