@@lienchen12 I think one of the earphones is shorted, but that was my mistake... I must have reversed the polarity. So sad! Lien, can I ask for your help? A friend is going to china next month and would like to buy just one side of the realme buds air 5 pro earphones... I saw that there are replacement parts for these earphones on the official realme website in China, but I didn't find any link to make the purchase... It's very difficult for me because I don't understand Chinese. So... Can you help me finding a link where I can buy just one of the earphones (the one on the right side) in your country? Thank you in advance for all your help
you must charge your earbuds first when it full charge disconnect earbuds from diy charger then you’ll see red and blue light it means bluetooth pairing
to turn off ( long press until lights off ) any kind of earbuds unused, scrap, or you can buy the cheaper one. the voltage is the same, you can use it just follow my video, thanks for watching..
Amazing idea love to watch it!
