Features of the headset are fairly basic. You get the typical answering, ending, and rejecting calls, last number redial, call waiting support, battery indicator, and the ability to transfer calls from the headset to the phone and vice versa.
We paired the Plantronics Explorer 395 with the Apple iPhone 3G. Thanks to Plantronics' QuickPair technology, we managed to pair the two without having to enter a PIN. Call quality was good on our end; we could hear callers clearly with plenty of volume, and their voices sounded natural as well.
On their end, however, callers reported quite a bit of background noise. Even in a quiet office, they could hear keys clacking in the background and a low hum. They could still our voices just fine, but only if we were in a relatively quiet environment like the office or the car. We wouldn't recommend this for extended outdoor use.
The Plantronics Explorer 395 has a rated battery life of 5 hours talk time and 7 days standby time.
