I be very surprised at how boom the bass be on these . I be always tell that earbud be not the correct way to listen to music cuz they do not deliver enough bass . these definitely do . another great factor be that when these be in you ear , they pretty much block out all external noise . they be pretty amazing . I could not believe it . I can not complain about the sound quality at all . my only issue be the control talk remote which be on the left bud . it weigh down on it make it uncomfortable to walk around . also it be extremely close to you chin which be another annoying factor . I be annoy with this so much which be why I be glad I find out about the `` ibeats htc\/ur beat '' which do not have that control talk thing so close to you face .
