The M110 features a sturdy headband, padded flexible earpiece and headpiece, and a fully adjustable microphone. It required no assembly and, in our experience, was extremely versatile. The microphone can be worn with the headband on either ear, and the headband was very light and comfortable to wear for long periods of time. The sound quality of the earpiece and microphone were both very clear during testing.

A noise-canceling microphone eliminates background noise on the M110, and makes your voice easily understandable to callers. There are also three levels of microphone volume, though there is no volume adjustment for the earpiece and, in our tests, we often had to ask callers to speak up.

The headset has a 4-foot cord with adjustable clothing clip to give you a wide range of motion. The M110 can be used with any cordless or cellular phone that's headset compatible and has a 2.5-millimeter jack. --Megan Dugan
