I was very happy with the appearance and size of the headset - but very unhappy with the performance. When using it, it never feels like it is secure. It just hangs off the ear, and everytime I'd turn my head to the side or bend down to pick something up, I felt like it would fall off. The sound quality was just okay on my end of the phone (I have a Verizon LG VX8600). But everyone I called said that they heard their voices echo and the sound was muffled. In fact, one of my friends refused to even speak to me when I was using it - the sound was that bad on his end. Several times I had to turn it off in the middle of business calls because they couldn't make out what I was saying. It ended up to be pretty useless. I exchanged it for a Plantronics Voyager 510 - it is a little bigger but I've been told that the sound quality is 100% better on their end and it's also better on my end.Plantronics Voyager 510 Bluetooth Headset with Multipoint Technology [Retail Packaged]
