If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your ears, you may not obtain the correct sound qualities or call performance. Change the earbud tips to ones that fit more snugly in your ear. Supreme Audio workout, relax, skate listening favorite tunes. Hear every beat of your music and let the bass blow UP! We put a mic in each bud allowing you to have 1 bud in and leave the other in the case, call and hear outside sound at the same time.
