I did follow what's being written above. It works now, but the battery life is not as it should be. After maybe 30 minutes 9f use it says recharge it plz. And ONE more thing! After disassembling and reassembling the right side bud had no voice at all, after few times of opening and closing the the right side's case, it produces a lowered volume voice. What's happened to it? Any tricks or ideas?
