JoesGE.com is a pretty cool place (depending who you talk to it might be more than pretty cool. But hey, I'm just writing this down so that it says something down here, because that's more professional right?) and if you're still reading along at this point you might as well sit down and grab some popcorn because this is about to trail on about how we are this premiere repair service located in Washington State North of Seattle in basically the "Armpit of the US" near Mt Baker (Mt Baker has the world record for most snowfall at 1,140 inches in a season). Even though it can smell bad around here we love the fresh air and being near the post office and in a quiet sleepy mountain town certainly gives us much closer access to Team Turtle and Team Beaver (Watch our "Who, what, when and where is JoesGE?" video if you don't get the reference).
All this to basically say that we are all addicted to coffee and stay in the warehouse for ridiculously long hours in order to keep up with the demands of the youth for these two-sided head audio devices and speakers that float when you throw them in the ocean or in your bathtub to test if they actually float. On top of that, we do like it when less stuff ends up in landfills so we hoard everything on shelves with wheels so that we pollute less, it just sits in our warehouse losing molecules slowly over time degrading to become smaller and smaller.
If you are still reading at this point you deserve an award, or a high five, or something because you must either be the most patient person on the planet, or you read blogs frequently. And if the latter is the case, then this whole thing must seem pretty short so let's keep going.
We do some really interesting things here at JoesGE which are frequently documented in our sometimes weekly sometimes never vlogs.
Also, if you are wondering how we keep up with the demands of the people so well, its because 90% of the people that work here are all Russian around getting things done most of the time. Yes, that was a pun, you are welcome. We hope you have a pun-filled day, because who couldn't use a few laughs? - วิทยาศาสตร์และเทคโนโลยี
Hello All,
We, unfortunately, do not repair these headphones any longer. We do still offer the parts and tools to do the repairs though. Here are the links for the parts and tools for these repairs.

Is there a particular reason why? Do the replacement batteries not last long?
if you watch carefully, it appears he melts the speaker diaphragm with the heat gun. I just did the exact same thing. Now I have to replace the speaker drivers. Be careful with your heat!!
надо было заклеить вокруг каптоновым термоскотчем
I noticed the same when I saw the video. I wonder if covering the drivers with a piece of cardboard or plastic would help
I didn't seem to melt, but just dislocate slightly because of the airflow of the heatgun...
Yes, it does look like that, and I would absolutely expect that to happen. The diaphragm is so thin that it will heat much more quickly than the thicker material enclosing the battery. I haven't tried this repair, but if I did, I'd completely cover the driver on that side with a masking tape so no hot air would leak through to it. It's likely this damage would not stop the driver from working, but it would have some affect on the sound, and possibly the longevity.
Another important thing is to take not to short the red(+) and black(-) wires, I recommend putting a small tape on them.
Love it. Bose recommendation for bad battery is buy a new pair.
No, you can just replace the single ear unit. They sell them online.
@@MrMJmusicLover Can you drop link here? I didn’t find it on official website, only ear pads etc.
@@het7644 I thought I was correct. I wasn't. You can't replace the whole single unit. It has to replaced (Battery) by you or a professional. Sorry for the incorrect information. 😕
@@MrMJmusicLover That's all right! Single unit would be too expensive anyway, especially right one.
I would never dare to do this myself without any experience. But I got to say, it's fun to watch. Good video, pal.
Thanks for watching:)
Would it be safer to cut the battery wires close to the old battery and reattach the new battery to the wires? Thanks
For such an incredibly expensive product, you'd think theyd make battery replacment as easy as gaming controllers or remote controlers
Ive wondered that before.
1:10 alternate procedure: sand down adhesive bleedout with 2000 grit sandpaper, pry open with flathead screwdriver as demonstrated.
Do you need to have the headphones 'learn' the new charge levels like with an old phone by draining and recharging fully?
Hi Joe, could you please explain why battery use 3 wires: +, -, what is 3rd. Another question: is it possible to use AA or AAA 3.7v batteries with more capacity or AA is incompatible by size? Thank you in advance.
don't use glue to hold the battery cover back in place, use a dab of silicone instead so it's easy to take out next time!
Exactly!! What I was thinking. Copydex and done
What brand and type?
@@petergriffinson1907 I like to use the 'whateverishandy' brand of type neutral cure
Trying to find this out everywhere but can't get any information on it. After removing the ear pad and felt insert, like you did, what the heck is that large white corrugated stiff ribbon like structure that is partially covering the driver. Why is it there? I've never seen any other headphone bock their drivers like that. I thought maybe it was there to deflect the midrange and the highs so that they wouldn't sound so sharp by going directly into the ear but honestly, this is just a guess. Do you know what it's there for?
Thanks a lot for the video! Just a question, could you please specify what type of heat gun you used here? Would 300w be sufficient for this?

Will this work for QC 35 II’s as well? Are there battery issues that people are having with these units? Thanks
Thanks for the comment. Yes, the battery replacement is similar for both models.

@@Joesge great! I've emailed you a question and depending on your opinion I will likely go ahead. Is there any way I can get it posted for less than $30US though?
I'm glad I didn't get rid of my QC25, still sounds great and only needs a AAA battery.

I just can't believe he didn't mention to test it first before putting it back together... :D what if the contacts are not properly soldered???? easy... pry it open again... hahaha...
Very nice tutorial, thank you very much. Before buying those expensive headphones, I wanted to make sure I'd be able to replace the batteries once dead
No problem. Glad we could help.
My battery just died used everyday for 5 years
@@jasonmackenzie3052 Mine, too. I think mine were 4 years old. I would use them everyday, all day. Then one day last week--DONE. I just called Bose and they immediately said if I would return them (they're out of warranty), they would sell me a pair of their updated Quiet Comfort 45 for $209 instead of the $329 they retail for. I'm going that route. More money than changing a battery yourself, but hey--at least I get a new pair of headphones for a decent discount.
@@ThriftDiving I ordered new battery was £20 then re-soldered the 3 wires works perfect again, first solder attempt :)
I suggest to first cut the battery wires, that will prevent any sort of shorts when soldering. Start with B+ (red wire). The wires are a bit longer than needed, I cut them at the bend. Then use some soldering wick to remove the excess old solder from the pads. It will leave the pads nice and clean for the new replacement battery wires.
Thanks for the video.
Cutting the wire isn't necessary, but if it worked for you, thats awesome.
Also, is it possible to put a slightly larger battery in? Thanks.
It may be possible to do, but we wouldn't recommend it
Thank you.
You're welcome!
hello, I'm thinking about buying Bose QC35 ii, and i'm wondering for how long you will have replacement batteries for selling, because currently they are sold out. Maybe could u tell the info about that battery Voltage, charging Amps? Just in case, because i dont like built in batteries which are hard to find.
RIm, thank you for watching our video. The batteries are typically restocked every 1-2 weeks. We suggest you sign up in the "Item out of stock - notify me". The amount of voltage it can hold is 3.7. The amount of amps is 495Mah.
Ruslan P
when i test the battery out of the headphones, the original reads 4v, the two replacements I have read 3.8 and 3.9v. As soon as I connect the red and black to the B+ and B- pins the voltage measured drops to 0v. There is just 1 ohm resistance between the + and - pins when the battery is disconnected. Any ideas what might be going on?

what is the name of this hot thing for quit the battery cover?
How can i replace the flex cable that connects two circuits!?
Thank you for putting this video out into the world. Its a fucking travesty that these are the lengths manufacturers go to to keep consumers from extending the longevity of a product they spent a lot of hard earned money on. I tell people to always buy electronics like this second hand and repair them yourself. Dont give these companies your money. Let someone else make that mistake.
Good practice Is to use a bit of foil over the speaker before getting heat gun on that battery panel as drivers are so easy to damage with heat
does somebody know if the replacement battery also works for Bose Soundlink AE2?
I do not think the battery work for both.
Is this the same for qc35 ii version ?
It is a very similar process.
A zoomed in B roll would be much appreciated
how do we get to the other side for the power switch fix
Thanks for the video! What type of battery do you use for the replacement? Is it the same as Bose uses? Where can I buy them? Thanks!
Thanks for watching our video. We use the same battery as Bose. We are now selling battery's on our website. Here is the link - bit.ly/2uGSTm2
Thanks A.P.
@F1ForFun This sounds like a super intriguing idea! Did you end up doing this?
@F1ForFun That's super cool! I don't think I need a guide, but perhaps a picture of the mod? I haven't actually got the qc35s but hopefully should be getting them in the next few weeks.
@F1ForFun oh no I'm gonna get these second hand for around £100 and replace the cushions and head band and hopefully the battery too. These won't have warranty. I'll be looking out for your post lol.
F1ForFun how did you attach the 3 wires to the battery? Mine are totally dead and wont charge. I got a soldering iron but i dont know how i would attach the 3 wires to the battery
just done replacing with a new one and still not charging. it blinks like its charging but even after 5 hours still not going green. it's not charging past the level i put it last to charge.
When i first charged it, it went to 70% then after i used it a little i put it to charge when it was 50% but not going past this and so on.
Thanks

Bravissimo
👍
Can we just cut the old battery's wires and weld the new one on the old one who sticking out ? Can we use a piece of tape to fix the cover instead of glue it again ?
I wouldn't recommend any of that.
@@Joesge why not? We need simple way to do this.
this headphone will outlived me
All thumbs here. Do you possibly provide a mail in replace the battery service? Thanks.
Thanks :) We sure do. We offer a worldwide mail in repair option. Follow the instructions on this link - www.joesge.com/pages/repair-services
@@Joesge Do you sell just the battery for people who want to carry out the repair on their own?
My headphones wouldn't charge so I bought a replacement battery and followed the guide.
The new replacement wouldn't charge either. I left it overnight uncharged and the next morning plugged it in again and It was charging. After 5-10 minutes it stopped charging now and won't charge anymore :(
Any ideas what could be wrong? Btw, thanks for the video guide.

not sure but i think so
Is that uhu glue?
Not sure
Nice demo. I have some doubts, however, about using a heat gun to remove the battery cover. Glue is weaker than plastic, pry it slowly and the glue will pop before the plastic. I had to change a battery on another brand, worked fine. Btw, you can find these batteries, generic with same specks, for under $5 on Amazon.
Can you post a link of one posted on Amazon? Can't seem to find the correct model/specs.
please give us more information ...
Thanks dude ! Make repairability great again.
Trump Lost Dude. Biden 2021 ❤️😊
You bet!
My daughter's qc35s aren't lasting as long as they used to. She went to Bose and they said it would cost $300 to replace the battery! Not impressed. I used to be a computer tech back in the Mac plus IBM PS/2 days so I think I will give this a try sooner or later. Thanks!

Where can I go to have the batteries replaced on my Bose QC headphones? This is just to complicated for me to install.

Or just go online and buy a single individual ear unit online and connect it to your existing headphones.
1:14 Ouch! That did hurt to watch.
You've deformed the diaphragm of that tiny speaker with your heat gun. Should have used some kapton tape to protect it.
could you post a better picture of the battery with all the information on it

removing or installing the Lithium-ion battery without insulating the wires before threading through the pcb is just poor technique - risk short circuit of the cell.
Hey, I'm new to this video and was wondering what I should do when replacing my battery. You mentioned that the wires should be insulated before installing them but do you really need to insulate them when taking the battery out?
I can't find these 3.7V 495mAh cylindrical batteries!

@@Joesge Do you have an idea on when you'll have stock again? It looks like these batteries are now quite rare, at least in a new condition..
Camera is way to far
никогда так не делайте
Using a heatgun will destroy your speaker!
You will need a Li-Ion with 495 mAh (53 x 11) mm for those who asked.
where do you get these from? I can only seem to find reclaimed batteries pulled from old units...
for replacement batteries search aliexpress, e.g. item 4000954250804
Hi
There is only one battery ?
Yes
The silicone is key, my battery just exploded in my qc 35.
crazy 🤯 send us a photo. @joesge on instagram
This is super helpful, and gives hope with regards to extending the QC35 II's useful life, but dang - $45 for that itsy-bitsy battery + shipping is overpriced in my book.
If you can find the battery cheaper let us know.
@@Joesge Oh, wow... cynical much?
One could argue that before your battery offering, the cheapest you could find a replacement QC35 battery for was Bose's own $259 out-of-warranty replacement service. How would frustrated customers react to Bose asking them to let it know if they could find it cheaper? Probably with about as much amusement as I'm feeling for your quick quip.
What can I say... capitalism rules! (I guess it won't be long before enterprising Chinese undercut YOU, though, so enjoy it while it lasts)
You could argue that. That is why we sell parts that are hard to get so we can help people who Bose doesn't seem to want to help. We have no issues competing. Seems to be working okay.
@@Joesge I acknowledge the fact that this will prove helpful to some people.
I merely pointed out that to me ("in my book"), for what it is (a diminutive, low-power battery that can't take more than peanuts to manufacture, and perhaps a few dollars more to roll down the supply chain) - this item is overpriced (arguably cheaper than Bose's outrageous out-of-warranty replacement fee, though still overpriced).
This does seem to be working for you and those biting the bullet, however, so what do I know... more power to you!
@@guyo68 while it is overpriced you need to think about it for a sec... do you thought of this before buying Bose headphone? That maybe someday you need to service them? Maybe next time just buy something more affordable in the first place? Try Sony, they make good headphone and I am pretty sure the replacement cost is a bit cheaper! If you bought Bose, do you ever think that the product itself is pricey than what you can get from other brand? So don't complain, just pay those $45 every 4-5 years and quit complaining, unless you have better alternative!
Beats me why Bose does not offer this service itself. It seems wasteful to ask customers buy a new pair rather than replace a battery within 10-15 minutes.
Because they want you to buy a new pair for $300
You can buy a single ear unit by itself online. Saves alot of headache.
We offer the service on our website
@@MrMJmusicLover where? I can't find that piece
@@vice1997 I thought it was sold individually but it's not unfortunately. 😕
why the fuck isn't it just a god damn battery slot like the last version
We also have been wondering about that for a bit
Instead of a heat gun I would use 91% isopropyl
Either way does work, the heat gun is set to extremely low, like 100 degrees F. Heat gun is just a little quicker.
All that work just to get a battery out? Why not just replace the single ear unit. A normal person would damage the thing trying to remove it.
Replacing the entire side of the unit costs more and takes significantly longer
There's just no fucking way you can perform in installing the battery in such a short amount of time no way Jose
Looks easy why so many crying about this on forums.
Remember you need magnification and an extra pair of hands otherwise you will be wasting your time I'm not lying again may God take my life if I'm lying
I thought there were 1 battery on each side...
There is a battery on one side only GoaTraveller :)
