and yes, it does seem to use a little bit more battery. It's totally lightweight and a nice snug fit in either ear. Recharge is pretty quick and it's nice having the "dual" charger where you can charge your phone and the BT at the same time. I'm just getting use to the "press" button to turn-on & turn-off the BT, but it's just a matter of doing it more often. I was at the football game last night with about 51,000 screaming fans and I was able to hear, but the party on the other side had a difficult time hearing me, and asked me to repeat several times. But, beyond that, the iPhone BT has been enjoyable and well worth the $90 I paid for "brand new in sealed box" condition. Everyone was commenting on the BT and wanted to know what phone I had!
