Motorola H780

The noise-cancellation button sits farther down the headset; it's on by default, but you can switch it off if you don't need it (if you're in a superquiet environment such as an empty office). You have to be on a call to turn it off, though, and doing so doesn't save battery life, so there's no real reason to do so. This button is teensy, and I found it tricky to push with the pad of my finger (perhaps it's easier if you have strong, pointy nails).

In my hands-on tests, the H780's call quality was mixed. Sometimes it was very good. But even though call recipients' voices sounded loud enough to me, I sounded tinny or muffled to them some of the time, yet crisp and clear on other occasions. One person I spoke with was dismayed to encounter some reverb on her end, and she found it too distracting. Background noise, such as music, sounded faint when I started talking. I turned off the noise-cancellation feature when I was in a quiet environment, and for the other parties it was hard to tell whether the crispness in my voice improved.

This model is one of the more reasonably priced ones among our latest headset test batch, but you have better choices with more consistent call quality.
