Pros: quick pairing to the phone.
Cons: connection dropped frequently
this bluetooth device is ok if you want to have headset that can be use for listening to music and talking on your phone. the battery usage is fine. the only thing I have a problem is sometime when i listen to the music, it will drop the signal and then pick up again. It is not a nice experience. this is also very cumbersome to wear if you want listening in stereo.
