Headset Sound Quality

Pay attention to a headset's sound quality. If you cannot be heard or people can't hear you, the headset is essentially worthless.

Because some people are just louder than others, volume controls can be very important. All models have an incoming volume control, but only a few offer outgoing volume control, such as the M12 Vista.

A second key to high quality sound is a noise canceling headset, which helps reduce background noise so you can hear your callers more clearly. (Bear in mind however that you'll pay around $20 more for this feature.)
