Good sound quality/price ratio for a stereo Bluetooth headphone. Works about up to 6-8 meters from the source without any problems. Pairing is easy (I am using 32bit vista), but you might need to restart programs(mp3 player,etc..) after pairing with a computer.Depending on your ear shape, it could be disturbing after a while. So you probably won't be able to continuously use this for over ~2-3 hours(it is slightly heavier than normal headphones, as expected). It is good and easy to use with cell phones and other sources as well, but note that many such devices use their own headphone as an FM antenna, so you might be unable to listen to the radio if you use this instead.
