I got a pair of KSC-75 and they sound fantastic being driven by my ZX2 and Sonett 2. Yes... it's COMPLETELY overkill, but they actually work pretty well in my office setting since I can still hear people calling me in person or on the phone. It doesn't leak much noise either as long as I don't play too loud, because the air conditioning helps mask low level sounds.I ordered the PE headband and plantronics pads as suggested by @shotgunshane . I should be getting them later today! These drivers really have some potential, especially at just $15. I noticed that when I push the drivers against my ears, I get a much better bass response. The headband's clamp should help in that regard.
