Just got my V-Moda Vibe duo set in. ::: v-moda ::: Had to find the right size of rubber ear fittings(included). Got them inserted and seated properly in the ears. WOW!! These sound fantastic. 5 out of 5 stars. They have: - a mic built in which works on calls(i tested) -function button that answers/ends calls(tested) -same button pauses/plays music -nice little storage pouch The button does call the most recent contact on ur history when u double Click it. Im still learning this headset, but the sound is awesome. Nice fathers Day gift from the wifey haha.
