My charging box fell and my buds flew out of the case. The left bud stopped working after that. After a day, the charging box started recognizing the bud was in the box so there's still some signs of life but the left bud doesn't connect to my phone or makes that sound letting you know its in your ear. My question is if it's worth opening the bud and if it could be a simple fix like the touch sensor being disconnected from the board because of the fall.
