Whilst the black ones ordered, and received, look great, I have a couple of reservations. Firstly, there does not appear to be a visible charging / charged light on the case, as referred to in the barely decipherable instructions obviously intended for the white ones, so it's not possible to know the state of charge, or lack thereof, and secondly, they proved very difficult to pair with Android equipment, and once pairing was eventually achieved, they keep disconnecting, needing to be reconnected on a regular basis. Perhaps I am doing something wrong, but the instruction sheet supplied certainly does not help. I was really looking forward to receiving these and using them, but have to say that I am not, at the moment, very impressed.
