Excellent sound on the side that works (L); however, the sound from the other side (R) is much quieter. I didn't make a direct comparison with another cable and other headphones before the return period expired. A request to the seller for Revain went unanswered; Consequently . . . There are too many other good options to risk this inconvenience for a small difference in price.
