Summary: I am using this device with my Galaxy S II Skyrocket, only for music though. The function is great; easy pairing, easy charging, good sound at respectable listening levels. I am able to turn off my volume limit, be careful if you do so, it can be VERY loud.
Pros: Nice sound and fairly easy to use. I like the joystick motion of the control button, I can get used to that. The built in SRS WOW works well.
Cons: The SRS WOW will fight with the spacial effects in your music player, use one or the other, not both. The earphone cable could be a little longer, it only just reaches my belt and I am only about 5'-11".
Summary: the first set i had purchased were headsets & this was very uncomfortable for me to wear....they fit behind my head & the fit i think was made more for a guy then for a girls smaller head. i decided to purchase these AUDIO-TECHNICA Bluetooth earbuds & give them a try.
