I have had my earbuds for about 11 months. They have always worked seamlessly. Last week I used the left one for quite a while and the battery eventually died on it. Now, it will not charge or connect. I have reset the earbuds, I have gone through online tutorials on methods to reset them, I have tried charging just the left one. I cleaned the case and the earbud. I checked for damage, there is none. I have tried every step I can find, and nothing has worked at all. Please help.
