Flip the headset over and you'll find a small in-ear earpiece clad in a rubber ear cushion, as well as a thin and flexible plastic ear hook. The H780 comes with a variety of different-size ear cushions, in case the one out of the box doesn't fit your ear. We found that it fit quite comfortably; it sits just outside the ear canal, and the thin ear hook made it possible for us to wear it while wearing glasses. It should be noted that the ear hook is not optional; it's needed for stability and security.
Features of the H780 include the typical answering, receiving, rejecting, and ending calls, last number redial, call mute, and the ability to transfer calls from the headset to the phone and vice versa. It has multipoint technology, meaning it can connect to two devices simultaneously. It also has a battery status indicator.
Like with other Motorola headsets, the Motorola H780 has automatic pairing when it's first turned on. We managed to pair it with both the Apple iPhone 3G and the LG Lotus. We made several calls to both landline and cell phone numbers. Each time, our callers could tell we were using a headset, and said we sounded rather harsh, with a tinny or robotic-sounding voice. We then tried using our headset outdoors and in the car. In those situations, callers said they couldn't hear a lot of background noise, and we were impressed by how well the noise cancellation worked. When we toggled the noise cancellation off, it was clear how much difference it made. So, while the H780 doesn't have the clearest audio quality, it does cancel out a lot of environmental noise.
The Motorola H780 has a rated battery life of 7 hours talk time and 8 days standby time.
