Features of the H790 include the typical answering, ending, and rejecting calls, as well as last-number redial, call mute, call waiting support, voice dialing support, and the capability to transfer calls from the headset to the phone and vice versa. It also has multipoint technology, meaning you can connect up to two devices at once.
We paired the Motorola H790 with the Apple iPhone 3G. Its call quality was quite impressive overall. On our end, we heard our callers without a problem with hardly any static in the background. Their voices sounded clear and natural.
On their end, callers did detect a tiny bit of buzzing at times, but it was not a distraction. For the most part, they could hear us loud and clear in a variety of situations. We tested the headset in a quiet office, in a moving vehicle, and inside a busy cafe during the lunch hour. In the noisiest environment, callers did hear a little bit of background noise, and our voice quality diminished a bit; however, we could still carry on a conversation. We also made a few test recordings on the voice recorder on our phone to verify their claims.
The Motorola H790 has a rated battery time of 5 hours talk time and 7 days standby time.
