This is not a comprehensive review. Just a brief warning. I purchased it to use on my tablet computer for speech recognition. The setup is extremely simple. It was done before I even knew it. The sound quality is typical of a Bluetooth headset, not nearly as good as the quality wired headset, which I expected, but not bad. What I did not expect is that this thing does not work with speech recognition at all. It makes so much beeping in the background which renders it completely unusable for speech recognition software. In fact, I could not even pass the training session of NaturallySpeaking Professional 10.1. If speech recognition is in your mind, don't buy this product. Otherwise, it is a fine product. Obviously well made, and quite comfortable to wear as well.
