I have used this headset now for several months after giving up on bluetooth because most are too big and bulky. This is the perfect size and does not interfer with the earpiece of my glasses.Audio quality is typically better than the actual headset I use it with. I do find I need to keep the phone within about 20 feet of the headset or voice gets a bit static sounding.One button to do all pairing, turning on/off, etc. can be frustrating at times as you have to hold it and watch the blue light to activate the right thing.The little coffin it sits in for charging also doubles as a convienant travel case to protect it.Due to the lack of a wrap around for the ear, I do find if I am moving a lot that the ear piece can slip out, but for most cases, walking in the hall/around the house and driving, it is perfect.
