This review is to compliment the one I have already submitted. I am very picky when it comes to electronics and sound. I've had these for over a week and wear them every night for TV watching. I have only charged it once and they still have power. The sound quality is comparable to Sennheiser or Sony high-end. Bluetooth reaches a long distance from the source, I can go to the garage, upstairs, even to the patio and still get good reception. The price range is unbeatable for the quality. They are very comfortable and light to wear.
