Holding the handset hurts my ear and elbow after about 10 minutes. But, because the headset is so small, I sometimes feel weird walking about talking to what appears to be no one in particular. I was able to obtain three headsets from two manufacturers Plantronics and GN Netcom. Because of, what I find, a heavy subjective influence on headset choice, I decided to plainly separate my objective and subjective evaluations of these three headsets. The Plantronics M175 is a convertible headset.
Conversion is easy and quick.
A fixed boom with a noise-canceling microphone juts out of the earpiece. The whole construction is sleek and sturdy. A noise-canceling microphone on a rigid boom is connected to the earpiece by a hinge. This allows the boom to be raised or lowered for comfort and voice quality. As with the convertible headset, the design is sleek and sturdy.
