Summary: Before you buy this headset, make sure it works with, what ever you want to use with. I returned it the day after I picked it up. I could hardly hear the dial tone, and could not adj the volume to hear the voice mail.
Summary: I've been using this headset occasionally for the last month to call into meetings while I work at home. Have not had any problems. I can hear everything going on and I have not had any complaints from the other end. It does lack a volume control, but the sound is at a good level already, so that has not been a problem.
