This is the best bluetooth I've owned. I've owned cheapies and more expensive bluetooth headsets, and the650E is by far the best so far. A bit static-y at times, but generally, the reception is good, and the people I speak to can't tell I'm speaking on a bluetooth. I like the gel earpiece, and I've never had to use the earloop. Never had a problem with it falling out of my ear, like some people complain about, even if I tip my head so the earpiece is down. The buttons are hard to push at first, but once you get used to it, it's a non-issue. I like the brightness of the in use lights, and can easily tell if it's turned on or not (just don't try to play hide and seek in the dark with it on). It's a bit bigger than some of the headsets, but still not big enough to be uncomfortable. Overall, especially for the price, this is a GREAT buy!!!
