I bought a pair of Cowin E7 headphones and I love them. However, I always forgot to charge them and they would go dead when I didn't expect it. So, I decided to buy another pair so that I would always have a charged pair to switch to.
Apparently, they have different "codes" or whatever and when I turn one set off and the other on, I sometimes have to fiddle around with the bluetooth and playback settings to get the current set paired up. Sometimes there are 3 or 4 copies to choose from in the "sound/playback" settings.
I have twice tried uninstalling bluetooth and reinstalling it. It might work for a day or maybe a week but the problem always comes back. For the past week, I haven't been able to connect either pair. Rebooting doesn't help.
