Features on the Jabra BT2080 are fairly basic. They include the capability to answer, reject, and make calls, call waiting support, last-number redial, and voice-dialing support if your phone has that feature. You can also easily transfer calls back and forth to your phone.
We paired the Jabra BT2080 with the Apple iPhone 3G. Call quality was decent, though it doesn't have very good noise-canceling properties. We heard our callers loud and clear for the most part. On their end, when we were in a quiet environment, they could hear us just fine. They did detect quite a bit of static and there were occasional drops in volume, but we could still carry on a conversation. When we were in a noisier environment, however, like outside in the pouring rain, callers could definitely detect background noise. Sometimes it was so bad they said they couldn't hear what we were saying. When we were in a moving vehicle, they could even hear the engine roar at times. On the whole, the call quality is good enough for occasional use, but not the best choice if you plan on using it in noise-heavy situations.
The Jabra BT2080 has a rated battery life of 6 hours talk time and 8 days standby time.
