We tested the Jabra BT350 with the Sony Ericsson S710a. After this simple pairing process, we were ready to make calls. Audio quality sounded admirable with little static or interference, but we had to adjust the headset's fit a few times to find the sweet spot. Callers said they could tell we were using a headset, but they didn't report any significant sound-quality complaints. Voices at times sounded a bit hollow, and clarity decreased in noisy conditions, but the Jabra BT350 performed well all around and compared favorably to the best headsets. If you work in construction, drive a convertible, or talk frequently in loud environments, you should take the BT350 for a test run before buying to make sure it's loud enough.
We were pleasantly surprised to find the Jabra BT350's vibrate mode for incoming calls, which is similar to the BT800's. It's shocking to feel your ear vibrating the first few times, but we think the vibrate mode is a nice addition to an already generous list of features. Other features include last-number redial, support for Bluetooth 1.2, call reject, call hold, and voice dialing. After 2 hours of charge time, the Jabra BT350 has a rated talk time of talk time of 7 hours and a promised standby time of just more than 8 days. In our tests, we coaxed 6.5 days of standby time.
