Connectivity Issues with the Life P2

Approximately 3 weeks ago Ipurchased the Life P2 of Amazon. Recently my earbuds have had connectivity issues eg. sometimes they won’t connect to certain devices, only one of them connects. I have also noticed them flashing in a way that isn’t shown in the manual. What they do is their lights are off and then fade in to on. They then go black and repeat. I have tried everything i could think of, like forgetting them on the device I want to connect to and setting the earbuds back to factory settings. I really don’t want to return them, as they sound so good and are really practical. Any suggestions?
