I really thought that the Plantronic's name meant quality. I gave up trying to keep this thing on my ear. Not doing my homework properly, I didn't understand that the conical ear piece is the part that hangs on to your ear. The rest of the frame is, I guess, for show. Its pretty unstable and kind of flops around in your ear. I never got comfortable enough with it to evaluate the headset for its sound quality. Another wasted $35.00 I am pretty soon going to give up buying anything on-line. There's something to be said for old fashion brick&mortar stores where you can see an item and try it before you waste money on it. This wasn't worth the time and expense to return.
