Features of the H12 include the typical answering, receiving, and ending calls, call mute, voice-dial support, placing a call on hold, last number redial, and the ability to transfer calls from the phone to the headset and vice versa. There's also a battery life indicator when the headset is placed in the charger.
We tested the Motorola Pure H12 Bluetooth headset with the RIM BlackBerry Pearl. The H12 goes automatically into pairing mode when you first turn it on, so the pairing process went very smoothly. It comes with two microphones to block out background noise and adjust noise levels depending on the environment, so we were expecting excellent sound quality. Although we were impressed by the incoming call quality, outgoing call quality was not always as smooth. On our end, voices sounded loud, clear, and very natural, with little static or interference. But on the callers' end, we heard reports of a background hiss plus a slight echo, while others had no problem hearing us at all. We tested it again in a noisier restaurant environment, and though callers still reported the same background hiss, they managed to make out what we said. This shows us that call quality can be patchy, which is surprising especially when you consider its CrystalTalk technology.
The Motorola Pure H12 has a rated talk time of 5.5 hours and a rated standby time of 8 days.
