Just brought them. Great sound quality, bass more tight, vocals clearer, dont have to turn volume so high as before to get same level of sound. Call quality is good, did not try in a noisy situation yet. Answer call, play track, pause, works, but skip track forward and back do not. Looked at the jack, it is a couple mm longer than supplied htc headset so it sticks out. Which makes the 4th band on the jack not connecting, that could be skip tracks control.
