Works perfectly with my PC and my Galaxy S2 (used with speech recognition software Dragon Naturally Speaking), quick pairing instructions in French and English. Comes with a car charger and two replacement tips (which I include poorly functioning, but good). Excellent battery life (300 hours standby time, approximately 7-8 hours talk time, about 2 hours to fully recharge), leaflet warns that the number of charging is limited but I can not say how much. The headset hurts a little at the beginning but it must be because I have not yet used and the fastening system appears fragile. Once in place, you forget easily. In terms of sound quality, good listener and my interlocutors hear me well but I only tested in a quiet environment. You can listen to mp3 but this is anecdotal, it is not made for that. Satisfied, therefore, this headset.
