However, the blood oxygen levels are very high (and not all that accurate). He kept thanking me over and over, and he was raving about them. Overall, these are very good headphones for the price point. Gave this a low review at first because I put it together wrong while I was sleep deprived. I have probably purchased a half dozen stands for my iPad and Kindles. While talking on the phone, I have had several people tell me that it was difficult to hear me.
