I am not using them anymore for fear of them catching fire while Im using them and am exchanging them for a new set. Now I paired them to my Lenovo Android tablet, all goes great to start with and the sound is really good, finish setting them up and charge them fully. Horrible design. First pair was all black, lived them but realized in 2nd summer they were starting to turn my feet black, that didnt happen in the first summer. The moccasins are comfortable. All plastic but not too cheap looking or feeling. The top part of the case has been misplaced SO many times. It is comfortable. I’m telling you, “amazing sound quality” is an understatement, it’s excellent. This recent purchase was not true to size.
