Hey! I have a pair of Ceppekyy S2 true wireless earbuds that have worked great for like 7 months. Until recently. The left earbud simply won't connect to the right anymore. Normally, the right side is the "dominant" side. It is the side that plays in mono mode, and the phone connects to that bud, not the left one. However, the left no longer connects to the right, and I actually found out that the left is now capable of working independent of the right bud. Weird. I've even managed to get both to connect to the phone, however audio only comes through one bud, and they aren't connected to one another. Also, just so I don't waste anyone's time, I have factory reset them, put them in the charging case, removed the device from my phone, and tried re-pairing. Those don't seem to work. Thanks!
