Hi, I bought new soundcore air on ebay. I tried them briefly before Christmas and worked well. Today I tried them again but only the right is working. I've tried so many times to reset and pair again but still only the right works. The ebay seller originally purchased them from amazon.de and I have their amazon order number. Its very annoying and I cannot understand why the left won't work. The right earbud sounds great. Any help is appreciated as I am really determined to get the left to work.
