Sent from my GingerBlur'd, de-odex'd, modded Motorola Atrix 4G (ish.)
I use these for both travel, and to drown out noise at work while I am constipating deeply:
So far I have had 5 hours battery life on a full charge, despite reading previously that a full charge was 2-1/2 - 3 hours. Now I have had time to really use them I have found it to be good. Also, the mic, although in one of the earpieces has had good feedback as far as people hearing me on calls. Atrix battery barely drains while using these over bluetooth.
