Query: Nice, deep, clear response

DEEP! LOW! CLEAR! I like a lot of music, a lot of it electronica, dance, house-like sounds that hit some very low notes. I tried quite a few ear buds, and none of them worked well at all. These head sets have a very low frequency response, actually surprisingly so: they are better than the full size ear muff style ones that I have. These are the best things I've attached to my ipod yet, and I'm very happy. I'm going to have to replace my desktop headset with these!
