The volume on the Plantronics Explorer 220 is so low that I can hardly hear the other party. I've read some very positive reviews about this product (which is why I bought it) and, based on my experience with it, one has to wonder, WHO ARE THESE PEOPLE?!?!?! The headset fits very loosely which makes the volume seem even lower. And because the fit is not secure, it's extremely uncomfortable. I've tried to raise the volume to no avail. I've had a Motorola bluetooth headset for two years (my second one) and only now have I started to have issues w/it. The Plantronics Explorer 220 is inexpensive compared to other headsets, but, in my view, a total waste of money at any price. Absolutely worthless.
