I bought this to use with both my mobile phone and was satisfied to know it also worked with my PS3 for online gaming via the Bluetooth identification.
This device charges quickly and has a surprisingly long battery life, it's easy to connect to all devices by holding the big button on it down and while the light on it flashes you scan for it using your phone/PS33/Xbox or anything with Bluetooth enabled.
The default passkey for this Bluetooth headset is generally "0000", although for security reasons you should change this as soon as possible.
The sound was better than the audio pickup, people claimed to have some trouble hearing me sometimes when i'm talking to them, but with the earphone hooked comfortably around my ear I could hear them very clearly.
The design is nice and stylish but fragile, this would break under any pressure but to be this small and comfortably lightweight there could obviously be some integrity issues.
The range of this is supposed to be only 10 meters but being something that spends most of the time on your ear or on charge when not in use I never found this to be a problem, and you can put your phone in your pocket and answer it using a button on the headset itself.
