Query: Excellent earbuds

Great sound, ok bass, and for me these fit well into the ear. They are comfortable even after an extended period of time. The rubber pieces that inserts into the ear are soft and flexible, yet I've never had a problem with them falling out (unlike other types). They rotate, too, so you can adjust the angle of the wires coming out of the earpieces.This is the second pair I've bought--the first lasted six or seven years, so no complaints there.The audio quality is quite good. I'm a classically trained musician, and pretty picky. Most headphones or earbuds have distortion and frequencies that are over-emphasized. This one doesn't have those drawbacks, and sounds clear and clean. In comparison with bulky over-the-ear full headsets, these earbuds are just a little low at the bass end, but I think that is going to be the case with any earbud.
