***Good*** sound good on listening music English voice instead of Chinese ***Bad*** terrible microphone when use on calling ,your partner calling cant her yor voice well.
sound is okay but microphone on any calling phone is bad also range of bluetooth when connected with the other device is so short if i connected with laptop and walked to another room that near with laptop room (5 meters) then its sign has interupted.
not absolutely satisfied from the quality of the headset, the sound is good while listening to music but unfortunately the mic quality is very bad, the person in the other side cannot hear clearly, it's look like I'm speaking so far from the headsets.
