I ordered one to try and was not disappointed. The sound quality and volume are excellent, and you sure can't beat the price. I ding it one star as it can be a bit cumbersome to put on, particularly when wearing glasses. This is a minor issue however, as I have ordered two more pairs.I have just reduced my rating by one star. Of the 2 additional headsets, one did not function at all (being replaced). Also, unlike the previous 2 units I have purchased, they came with the shortest length ear-gel. This makes it very difficult to use, at least for me. I must constantly push on the unit to get adequate volume into my ear.These work very well, just be sure you are getting the appropriate length ear-gels.
