I really liked the design of this bluetooth set. I looked all over for it. I wanted a stereo headset that I could remove or drop one earpiece so that it wouldn't look like a stereo headset (for use at work.) I planned to listen to books on tape during boring meetings. :) But this headset was very uncomfortable after just a few hours and didn't transmit my voice well -- people complained that I was too loud and hollow sounding. Probably because the mike is on the ear piece, no boom. Anyway, I wish it could have worked better. No problem with returning it for a refund.
