You legend! Bought second hand - 3 lights. Called Bose who said “you can buy the new QC earbuds for £185”…. Found your video, 5 seconds with a 9V battery and a couple of paper clips on each one and they’re happily charging away!
It worked!!! I had a broken USB cable, i cut a short piece and made to wires for + and -. I had a used 9V battery at home. Attached plus to plus and minus to minus and hold them for 10 seconds each. Now they're charging 🎉 🙏🙏🙏🙏🙏
Just wanted to confirm that this worked! I used 3V and 0.1A, charged them for a few seconds, then I got one side to charge in the case. The other one would not, even though I tried a few times. I then tried putting the faulty one on the "wrong port" in the case and it also started working. I then used the "working bud" on the side of the case that wouldn't charge, and it started charging. After that, I could place both buds into their respective case spots and now they're both charging normally. I assume that the charging ports get into some kind of error state, which denies charging under certain circumstances. If anyone reads this, try the solution suggested, and if one side still does not charge, try switching the buds in the case, that worked for me. Thank you sir, that was very helpful!
It works!!! I bought a used pair of sleepbuds, when i got them, the charging case was showing the 3 dots meaning that it was not charging, so i applied 8V from a car battery for about 2 secs on each earpiece, then i put them in the case and the side lights started blinking, while the 3 dotted line, had the 5 dots turned on.. Many thanks!
Hi, thanks for the video. It makes sense. I have Bose sleep buds 2 and they are doing the same thing. Just a question though, what did you use for the power and what output did you use?
Well for that purpose you usually use a power supply. As you need 1.8v but it will definitely not hurt to try it out with AA battery. Maybe it will be enough to wake it up.. only suggestion is to check with multimeter and get the polarity right.
Interesting. Thanks for sharing. Maybe it creates some electron movement that revives the battery.. because when you apply + to - you are discharging the battery at that moment.
Difficult to say.. try leaving it on the charger for longer time or plugging in and out. Haven't opened it to know for sure but these two tricks usually help with deep discharged Battery.
I have the exact same problem in the video, but it is with my left earbud. How do I go about doing what you did? What is the equipment I would need? Or is there somebody I could take it to?
I have two pairs of these and a pretty good amount of electronics experience. SMT soldering, arduino circuit design, etc, etc Have you tried opening the buds? If so can you do a video describing how they’re assembled so (hopefully) we could reassemble without breaking anything very important.
Hello sir, i have the same problem with the left side but i have the Bose SleepBuds 2 (Second generation) which have different type of charging system , there is 3 points at the bud but I don’t know where is the + side or - side. Can you please help me with this. Thanks you for sharing this
Actually, you don't need to know which one is the + side or -side. Just use a power supply (a higher voltage) to wake it up and rub the 3 points with a metal needle. My second generation works fine again.
Sure it's possible to use batteries in series to get the right voltage but you will not see what is happening as power supply shows you if there is some current flowing or not .
Well I believe it's not as easy as that :) we should separate two cases one where it is quite new but it was left to long without charging then this trick works ok but if the battery in the earpiece is done this repair could revive it for a little bit but it still is at it's life end..
Bon, je n'ai pas la subtilité technologique de vous tous, mes écouteurs étaient inertes, je leur ai balancé direct le courant d'une pile 9 volts sur les bornes et ça les a bien réveillés après un an et demi d'absence de charge. Merci !
high probability is that internal battery was deeply discharged or died.. you need to take the case apart.. didnt had achance to do it till now so no tips on that.. sorry..
it's not 100% success, there are a lot of factors as how long the battery is discharged and so on. and you should have some basic electronic knowledge going through these tutorials.. I use a power supply to set concrete voltage and amperage, and multimeter to read out pins on the headset itself. additionally there was some comments that stated that reverse polarity feed in to headset helped to revive them as well.. but all these advise are on your own risk.
9v feels a little bit dangerous for this purpose, if someone else would try this method, do use it in very short periods of time. Glad it worked out for you and thanks for sharing your experience!
I think it's more suitable if you left them for a while uncharged if battery starts to degrade not sure if this trick really helps.. it's quite specific chemistry battery that longevity people complain..
If it goes short circuit there is no return in any battery I would say.. as much as I checked it is quite special chemistry and I would go very slow with the voltage and always make breaks and check if it charges on the original charger... To anyone who may read this comment and could use this advice... Hopefully Bose will come up with a more robust small battery technology...
As some comments suggest short mixing doesn't affect it but long one could brake it. It's not a 100% success option.. I believe if the battery is discharged for a long time or is damaged by itself, this method is not going to fix it..

I used 5V and 0,2A for a few seconds and I can also confirm, that this does work! Thanks

Same. Worked for me at 4v and 0.1a. Thanks for this!
It works! Thank you so much!
Nice :) thanks for letting me know;)
Hi, thanks for the video. It makes sense. I have Bose sleep buds 2 and they are doing the same thing. Just a question though, what did you use for the power and what output did you use?
How do I apply a small amount of voltage? What device / wiring would I use? AAA battery? I am a novice with electrical tools
Well for that purpose you usually use a power supply. As you need 1.8v but it will definitely not hurt to try it out with AA battery. Maybe it will be enough to wake it up.. only suggestion is to check with multimeter and get the polarity right.
Thank you for this great job :) I solved my problem with your sugesstion :) süper 👍
Glad it was helpful! Thanks for the feedback.
seems to have jump started mine to charge again, after a couple of years of non use, thanks.
I applied 9V with two standard batteries in my sleepbuds 2 (3 dots). It works after applying the + to the - for 10 seconds.
Interesting. Thanks for sharing. Maybe it creates some electron movement that revives the battery.. because when you apply + to - you are discharging the battery at that moment.
Hi, what about if the case is not charging at all?Thank you
Difficult to say.. try leaving it on the charger for longer time or plugging in and out. Haven't opened it to know for sure but these two tricks usually help with deep discharged Battery.
I have the exact same problem in the video, but it is with my left earbud. How do I go about doing what you did? What is the equipment I would need? Or is there somebody I could take it to?
I believe any electronic repair shop could help you. Power supply with variable output and Multimeter is what you need.
Worked fine with my left bud (series 1) tried it with a usb cable and my computer. The bud woks fine again.
Manuel... I don't understand what you did can you explain it again? One of your earbuds wasn't charging So you used a USB cable?
@@Lori68N I think Manuel took apart the USB cable and applied the voltage directly, since USB is 5 Volts. That's my guess
what is the polarity of the left side?
What device do you use to apply voltage to the pins?
power supply with custom settable voltage and amperage
I have two pairs of these and a pretty good amount of electronics experience. SMT soldering, arduino circuit design, etc, etc
Have you tried opening the buds? If so can you do a video describing how they’re assembled so (hopefully) we could reassemble without breaking anything very important.
No haven't done that. I assume it is glued in so some heating would be beneficial for disassembly..
Sir i have bose quietcomfort 30 headphone but I has some problem I wana to repair .how can j contact with you??

@@dominiquewang1176the 3 points on the sleep bud itself? Not the pins on the charging case right?
@@gringoloco8576 the 3 points on the charging case
@@dominiquewang1176 哥们可以说详细一点吗，具体用到了多少V和多少A，然后“rub the 3 points with a metal needle”是指用一根针搭在3个触点上，然后给针通电吗？非常感谢！
Is there any way to do this without any fancy machines? Using a battery and some tin foil, would that work?
Sure it's possible to use batteries in series to get the right voltage but you will not see what is happening as power supply shows you if there is some current flowing or not .
It’s so crazy this is a known issue and Bose does nothing but offer for you to buy them again…

Sorry in the app CZcams doesn't let me copy your comment to translate it.. if you need some help post a translated comment.. Thanks!
What device did you use as the trickle charger?
Adjustable power supply where you can set voltage and amperage according your needs..
My case does not charge at all when I plug it in. The lights don’t even turn on. What do you recommend i try.
high probability is that internal battery was deeply discharged or died.. you need to take the case apart.. didnt had achance to do it till now so no tips on that.. sorry..
Can someone please give step by step instructions on how to charge it and what they used?
Same here!
Yes!!! Like I have no idea what he is describing 🫣
it's not 100% success, there are a lot of factors as how long the battery is discharged and so on. and you should have some basic electronic knowledge going through these tutorials..

Well, I was at my wits end, and this worked. Are used a 9 V battery and aligned it with the contacts on the earpiece and it seems to be charging.
9v feels a little bit dangerous for this purpose, if someone else would try this method, do use it in very short periods of time. Glad it worked out for you and thanks for sharing your experience!
Nice one
I was able to fix the right side with it, but unfortunately not the left side.
In fact, it completely broke the left side.
I think it's more suitable if you left them for a while uncharged if battery starts to degrade not sure if this trick really helps.. it's quite specific chemistry battery that longevity people complain..
@@letsfixitgarage My power supply went directly into the short circuit shutdown. After that, I was no longer shown an error, but nothing at all.
If it goes short circuit there is no return in any battery I would say.. as much as I checked it is quite special chemistry and I would go very slow with the voltage and always make breaks and check if it charges on the original charger... To anyone who may read this comment and could use this advice... Hopefully Bose will come up with a more robust small battery technology...
I mixed up the plus and minus on the left earphone, now it does not come to life in any way:(
As some comments suggest short mixing doesn't affect it but long one could brake it. It's not a 100% success option.. I believe if the battery is discharged for a long time or is damaged by itself, this method is not going to fix it..
