I run a mix of LG, Blackberry and Motorola phones btween work and personal. When I first got the H700 it was a good solid connection to phone with excellent audio. After 2 months of heavy use, the Btooth connection would reset w/o warning...callers would complain about voice audio quality and battery life was horrible at 6mos. Noise cancelling was poor but the headset was rather light plus the power supply could be used to charge both phone and headset and vice a versa. Now with headset dead...at least I've got a spare phone charger out of the deal
