At first this headset seemed fine.. I would say for the first 5 calls. Then after that everyone I called complained that they couldn't hear me and there was a lot of noise on the call. This was a total waste of my money. I was using this headset with a Blackberry Curve and a headset adapter was needed with the headset. I don't think it was the adapter because another headset worked fine. As far as the fit of the ear piece, that was okay, it was hard to hold it in my ear at times. The little wire that comes down to your mouth is very flimsy also. The bottom line is, I definitely wouldn't waste your time or money on this headset.
