It may have great voice quality, it may have great other features, but if you are constantly missing part of the conversation, you'd be better off using two cans and a string!

Good call audio quality, there is no disturbances or noises during calls and easily connects with my Samsung Note 3.Only problem is with signal strength, after two rooms or like 20 feet either voice will be breaking or call drops and that does not bother me much as my main purpose of having this Bluetooth headset is to have hands free calling.

Good sound quality on both ends of the conversation.

Yes, you can get excellent music quality from some over the ear headphones or whatever, but for the convenience of having a tiny BT in your pocket and casually listening to music on the plane or train, yes, these are good enough.

Not as good as my first M165 but, much better than another brand that I purchased.

Bought the Plantronics M165 Marque 2 headset for my son 2 years ago and it’s still working as of today.

Also, people on the other end of the line said my voice didn't sound as clear as when I used the phone handset.

They sent me instructions on how to get it fluffed up, and followed up with me to make sure I was satisfied, as well as encouraged me to reach out to them if I EVER have any problems with the pillow
