Summary: I'm happy with the headset, but it is not able to access all the features on my phone. Instead it has its own features that are similar. One negative is the volume control, there are only three levels low, med, & high. You can not increase loudness by upping the volume on your phone, for me the high setting is not loud enought. I'm in an above average noisyy environment. I need to cover both ears to hear or move to a quieter area, which is not always possible.
Pros: Not documented but, it has voice dialing. Just press the "front button" twice. The voice answer feature works just great for me as well. A2DP streaming. An on / off slider switch. It is everything I would want in a headset.
Cons: None. Really! I am not a fanboy. just a happy consumer. OK, well maybe it could be better if they included a lanyard so men could carry it around their neck if they do not have a shirt pocket. I have one from a old Plantronics BT headset and it works g
