We tested the headset on the Nokia 6820, the Motorola V600, and the Sony Ericsson T616. Although the audio quality exhibited some static, it was very good overall, with plenty of volume. Motorola promises a battery life of 5 hours of talk time and 4.2 days of standby. In our tests, we met the rated standby time. For more Bluetooth headsets, check out our Bluetooth headset roundup.
