I bought the Tune225TWS airbuds because they were 50% off. I quickly ran into the problem of the right one not charging as well but I think I found a solution! ❤️ I was at Starbucks and I just grabbed a paper napkin, put some hand sanitizer on the napkin the wipes the long end of the airbud with it making it wet, then stuck it into the charging case. STARTED CHARGING IMMEDIATELY ❤️
