Summary: I've had this device for 2 months now, and I can honestly say it's an ok device. The ear loop is not that great, mostly cheap plastic and can not be switched to the left ear without breaking it so your stuck with it being in the right ear.
Pros: Signal quality, sound, recharge time, length of listening time, multiple rubber ear fittings.
Cons: bulky, falls out of big ears, uncomfortable after about 10 minutes in your ear, non-adjustable ear loop, mic fails to work in windy situations, easily picked up by other BT devices when trying to pair to cell phone.
Summary: The sound quality is poor. I was able to hear a lot of static. The headset itself is light, but no matter the earpiece used, wearing it was not all that comfortable, especially for extended periods of time. Nor is this headset comfortable for people wearing eye glasses.
