Hi, I am sorry to hear you are having difficulties charging your Buds. If one or both of your Galaxy earbuds are not charging or turning on, the issue may be with the earbuds themselves or the charging case. Using a charger that isn't approved by Samsung may cause charging malfunctions; it's also possible that the earbuds may be damaged. You can try fully charging the case, checking the earbuds for damage, or restarting the earbuds. try these steps: https://www.samsung.com/us/support/troubleshooting/TSG01206422/
