Было ровно точно так же. Только ещё спустя пол года снова перестали заряжается. Сброс настроек нивелировать проблему. Но, до следующей зарядки. Собственно по этому нашëл это видео, чтобы выяснить причину, и устранить её, окончательно
This just worked for me. Its the right ear side to open. I did left first in error. I couldnt locate the little diode. As I was wiggling the wires the headset turned on, declared battery full, and is now working fine. Thanks for this video.
I replaced the battery on the Q20 last December with 1000mah (it had 720mah)-- but now the headband plastic is falling apart (last few inches up to the pivot points)! I braced it with new plastic and duct-tape. If I get 2 years the $10 battery will be worth it. Otherwise it works pretty well, with few glitches.. sometimes the audio is sent at a higher tone when listening to speech.. I have to turn off and reconnect to the source. I kept the Q20 because it has higher total volume than the q45. If interested, the battery size was 10mm thick, 25mm wide, by 30mm long (102530) @ 1000mah this is a rare size but it exists on aliexpress if you search hard enough. I've used premium chargers, so I did not burn out the diode on mine.
goddammit, in my it's already removed. also, I believe the problem could be in battery (left side). I will try to find it. But it works only with p2 cable that came with it.
My red light was coming on and then turning off after less than a minute. I think your video might have indirectly showed me the problem by mentioning that 3A is too much. I have an older power bank that delivers only 2.1A and it's able to maintain the charge. So thanks for the help!
Thanks so much for posting. My Q20 did not have the diode BUT by disassembling I could see one of the buttons was displaced and jammed. By repositioning the button, the charging works again. Without your video this thing is just a boat anchor. ;-)
@@marcelinodelfin1747 That's what some people have commented below. My headphones are like 3 years old, so maybe they are an older version and the new version changed the circuit board?
