- BOSE Headphones Models QC15 and QC25 fail regularly in one ear. Make yourself happier by fixing them!
This is a tutorial video on how to replace the broken speaker in BOSE QC25 and QC15 headphones. As always, please thumbs-up and subscribe for more repairs/technology related videos from Dubious Engineering!
BOSE noise cancelling headphones are very well built and use some fantastic technology to reduce ambient noise primarily by employing a microphone directed towards the outside environment. The outside facing microphone listens to the noise outside and plays a small amount of that outside noise data back into the headphones with the waveform phase shifted out by 180 degrees effectively cancelling out the interfering noise.
The drive speaker in each earphone uses very fine wires to maximise the drive efficiency and enhance the sound quality of the speaker. These fine wires easily break and as such, one speaker can fail to an open-circuit condition. The speakers normal impedance should be around 32 ohms. This can easily be tested with a multimeter.
To replace the speaker, you will need a hair dryer to help loosen some of the rubberised glue bonds. You will also need some replacement rubberised glue such as CopyDex. You will need a small phillips crosspoint and a small flathead screwdriver. You will also need a replacement speaker which can easily be found on eBay. A soldering iron and some basic soldering skills will be required.
The process is all relatively simple… Remove the ear cup and the internal cloth by hand, undo the screws and the back will come-off. Undo the two screws for the speaker enclosure on the QC25. Unsolder the external speaker wires and using a hairdryer, warm up the whole headphone so it is slightly hot to the touch, using a flat blade screwdriver, pry the speaker enclosure off. Unsolder the internal speaker wires and take note of which wire is connected to which terminal, it is important that the speaker is wired back in the correct phase. Again, with the hairdryer heat the speaker and carefully pry it from its position with the small flat-blade screwdriver. Replace the speaker, solder the internal wires, and glue in place with copydex. Re-assemble the headphones in the reverse order. Keep the headphones face down on the table and wait for the glue to dry before turning the headphones on and testing them.

Dubious, I have repaired my expensive headphones using this video as a guide. Thank you!!
Now that’s very satisfying to hear!! Well done!! I’m so happy to have helped!!
Here's an upcoming project... ua-cam.com/video/yDuAM026Zg0/v-deo.html
@@DubiousEngineering where can we get replacement speakers?
But how to get the new n original drivers
@@deepaksahu6075 It's been two years so I don't remember where I got them from, but I found them with a google search.

Is the quality is QuietComfortable ???
Quiet Comfort ... but yes!! You got it!!
Where do you buy the replacement speaker ?
Type “Bose qc25 replacement speaker” into eBay... it worked for me!
Had a pair of QC15s for over 10 years and the right channel finally went out. Was able to fix it in less than five minutes using this video. Amazing. Thanks!
Epic!!! Thanks 🙏 for your positive feedback!!! :-). Glad to have helped!!!
My custom color QC15 cutout randomly one day - Bose customer support was super helpful, saying they couldn't be repaired, but they'd offer me $90 off a $300 new grey pair. Watched this video, $22 on ebay and 3 days later, good as new. Thank you!
Thanks for sharing! - Really happy this helped you!
Thank you very much for a detailed and comprehensive guide! I've just fixed my just-out-of-warranty Bose QC25 with this video as a guide, and I am now enjoying Scorpions - Rock You Like A Hurricane on the headphones. Much obliged!
Fantastic !!! Thanks for taking time to pop me a message!! ... I’m really happy this has helped!! :-)
2 years without using it because of this issue, and now it's working like a charm now thanks a lot dude
Glad I could help!!
Hi there ! Thanks so much for this video that made me repair my qc35 i. As already said in other comments, the hair dryer is not enough to unseal the black plastic protection. I took a thermal cleaner and a big amount of strength on the screw driver. Then I souldered the black wire directly from the speaker to the circuit board (initially it went through the black plastic cover). In the end it works again with 280€ still in my pockets 👍🏼🙌🏼
EPIC!! - Another sucess story!! - So good to hear!! I hope I haven't counted this sucess twice.. :-)
Fantastic ! Thank you so much Howard 👍
I fixed my QC15’s following your UA-cam guidance.
BOSE refused to help me and told me to just buy a new headset. Even while I have always handled the headset very gently the right speaker suddenly stopped working. Using the multimeter I could confirm the driver to be the problem. BOSE must be using low quality components because this was already the 2nd BOSE headset that had a driver fail on me.
I ordered a new driver on AliExpress and for about €5 I fixed my headset! 🎉
Thanks again!
Oh dude! .. yes! Well done! Thanks for the positive feedback! ☺️
I just completed a headphone repair for the second time. After the first repair on the right speaker, the new speaker only lasted a short time before dying like the original. Fortunately, when I ordered the replacement speaker, they sent two replacements and I kept the second one in the event that I needed to repeat the repair. Thanks for all the tips, especially the hair dryer idea. I even used a multi-meter for the first time which indicated that the speaker was indeed bad, and the new one good.
Really glad it helped!!
Thanks, that has just got a pair of QC25 headphones working again, the usual right earpiece fault on a pair bought in 2015. Only thing I got wrong was managing to break the wire through the cover while removing it! That's saved me buying a new one, thanks again.
Yaaaaayyyy. :-)
Managed to follow this no problem - my 1st time soldering! - thanks for this guide - saved me a small fortune :)
Excellent news!! Happy to help!! All the best!!! Howard
Repair of my QC25 worked out very well due to this video. Thank you
Great news thanks 👍
fixed my QC 35 ii left speaker using this video. superb.
Happy days my friend!! Share and thumbs up please :-)
Thanks for the post. My left one went out too. I’ll be doing it this weekend
Very helpful. I dropped my QC25s and the right speaker became dislodge and rattled around in the capsule. I couldn't get the thing apart despite removing all the screws I could see. Saw this video, waited for wife to leave the house and broke out her new hairdryer for a bit of non intended use ;) All fixed thanks!
Pahahaha.... :-) Excellent!! Well done!!
Hi...thanks for this video! I was able to find Bose replacement drivers on eBay, and fixed my headphones with your excellent guidance. Many thanks!
Magnificent to hear!!! Glad you got it sorted!!!
Thanks so much, I’d got them apart and worked out there was a fault with the speaker but no clue about next steps. After watching this I got the part of amazon and fixed in a jiffy.found it easier to push the speaker out from the inside with a screwdriver...my glue didn’t melt with heat. Great!!!
Great work Graham!! Glad this helped a little!! Sub for more!
Great video bruh! Just fixed my QC25 for less than $10 USD, in a bit less than one hour... you're the man!!!
Glad I could help!!!
I believe even the new ones, the cover is still glued - mine got a bit over hot but a bit of patience and it did come off. Thanks a million though, saved me a fortune to replace headset!
Magnificent to know this has been a help!! These messages are the ones that encourage me! Thanks!!
Thanks For making this video! So happy to have working QC25s again!
So happy to have helped!! Tell your friends and subscribe :-). Whoop!!!
Fixed my QC3 headphones today using this vid as a guide...mine were from 2009 and I paid about $300 for them. Challenging because the little crescent shaped board had a hole in the middle through which Bose ran two wires for the noise cancellation (?) so a bit more involved since these two extra wires have to be un-soldered before the board can be removed to access the bad speaker. Thank you, thank you, thank you!!! Ken in the Philippines.
Excellent Ken!! - Enjoy the headphones!!
Thanks it worked, this was my first successful soldering job ☺️
Great work Oscar!
Fixed my headphones AND started learning a new skill - thank you sir!
epic to know that my little video has helped sort your issue :-)
Thank you for this guide, I was able to get my QC35 back running again, yay! But they must have changed the glue between QC25 and QC35, getting the black lid off was as tough as pulling teeth for me! It took me several iterations of heating and prying, heating and prying until it gave way eventually and I had to put a few dents in the plastic. But at last, they work now. :)
Great to know you are back up and running - BOSE are evil for changing that glue... :-(
@@DubiousEngineering They are! Also, they removed the screws that hold the black lid and instead have plastic pins with molten tops, so you have to drill the holes out. They *really* don't want to you repair your headphones... considering dropping BOSE for my next headphones because that's such a dick move.
nRXpAa8E6UML spread the word man... they have a speaker that fails after warranty and they are locking it down.:: so unfair... needs exposing
Where can I buy the replacement speakers for the QC35ii?
Another successful repair here, thanks for the nice clear close ups and little bits of advice.
Great news! Glad it was a helpful video 😉
@@DubiousEngineering Was a enjoyable watch too 🙂
Thanks, Headphones working again , followed video step by step , you made it very easy
Great news!!
Thanks a lot. I have just repaired my QC15 following your tutorial ! Great vid, keep on the good work !
fantastic! ... great to hear this video helped! thanks for your kind comments!
You are a lifesaver! replaced the left driver, no problem :)
Happy to help!!
Merci beaucoup ! C'est un tuto clair et super utile! Je n'avais jamais rien souder et là j'ai réussi a réparer mon casque.
Mon Ami merci boucoup... ave vous un bon sware
Note to QC35 II owners:
It seems Bose changed the desgin of the speaker cover a bit, I had to break 2 melted down screwed around the speaker housing + the glue isn't nearly as weak as shown in this video, you will have to heat up the glue quite a bit and use more force to pry it open.
Good luck
Yes, what a nightmare, and thenks for adding valuable information!!
Thanks so much for making this video, everything went well when I fixed my pair of headphones. surprisingly easy to do
Really happy I helped! Great work!! :-)
Thanks for the video. I was quite sure the issue was with the speaker but after measuring it's resistance I have my doubts.... 31 Ohms. Could the be with the motherboard then?
Oh and also I measured the resistance without prying open the speaker compartment, just across the 2 wires that come out of that. Shouldn't matter but still..
The speaker should register at 30 -34 ohms so sounds ok!
Well, not much to add to the other comments except yet another Thank You! I probably saved a lot of money, but also had some “fun” seeing what is inside these (QC25s) and had an excuse to buy the TS100. The hairdryer tip is worth the price of admission...and your accent reminds me of my dear British friends (Hemel-Watford area) whom I cannot see during these COVID times. So Cheers and Happy New Year...may it be better than this one. :-)
Awww cheers Edward!!! Really happy it helped!!! Take care and have a wonderful Christmas!!! Howard
Thanks Howard...Hope you and your loved ones are safe and healthy. :-)
Fixed my QC15s with your help, thanks!
Gleb Billig epic! ... these are the messages I love :-)
Would you please advise where I can get the part? Thanks
Thank you very much for this video. You just saved me 330€ !
Me weldings are not as pretty than yours and will prbably not hold a very long time but now, I know how to fix it.
I don't see any difference with the speakers I bought "2PC/Lots 40mm Replacement Speaker Repair Parts for Bose QuietComfort QC2 QC15 QC3 AE2 OE2i 40mm Driver Headphone 32ohm" on Amazon from this video RC-WFHleXeY wich was a great second support.
Thx a lot dude !!!
Just glad to help really 😍
Hi. I have a pair of Bose headphones which I acquired from someone else. The Bose website says that the serial number corresponds to a QC35 Mark I. They look like the QC25's in your video and initially disassemble in the same way. However, my blown driver is in the right side and when you open it up there are two differences. Across the back of the black plastic cover over the driver there is a ribbon cable joining the main PCB above the driver to a subsidiary one at the bottom (I guess this is the controller for the volume etc switches which are located near the bottom of that earcup). OK, no probs there, it is held in place with something like white wax so we can cut through that and flip it out of the way. But then the plastic cup over the driver refuses to yield. Not to moderate heat, not to not-so-moderate heat, not to brute-ish force. Can't shift it. Also the cover is not roughly round as yours is, its more triangular with rounded corners. There's no doubt they are genuine Boses - all the PCBs are branded etc - but they don't appear to be either of the ones in your video nor anyone else's here on UA-cam. Any thoughts? Come across any like this? Any advice gratefully received!
Wow!! Those sound special!! I have never seen anything like you have described... if there are any part-numbers on the PCBs or any application specific ICs consider trying to google those part numbers, that may lead somewhere... I’m sorry I can’t help... best, H
@@DubiousEngineering OK thanks. Since they appear to be non-repairable and since I have nothing to lose anyway, I might try cutting through the plastic cup with a hot scalpel and then attempting reassembly with superglue or epoxy or something. I doubt it will work but just maybe...... I think this is pretty criminal on the part of Bose; they must know from their support teams and quality control stats that the drivers are prone to failure and yet they go from a just-about replaceable design on the 15s and 25s to a completely locked down one
on the 35? Poor.
You are exactly correct... they made a commercial decision to screw the consumer and make more money... good luck with the repair!
This doesn't make me ever want to rush out and buy a product that will fail in a year. Glad you can fix them, and this will help lots of handy people do the same.
Yeah BOSE always meant quality to me... but there is a big chunk in their armour!!
Got a pair of QC25's...had them about a year, thankfully they're still working fine...
Amazingly... they tend to die after about a year! ... just outside of the warranty... give me a shout if they do, and you can’t be arsed to fix them... apparently I’m getting good at it!
D'oh...its the 35's I've got...Are they affected the same way?
I'm not seeing so many people complain about the 35s. Perhaps they fixed it!!
Same issue with 35s. I am going to check this weekend.
Just fixed my QC25 !! Thank you!!!
Epic!!! Well done!!! Thanks 🙏 for letting us know!! Whooop!!!!
You saved my Bose QC25, thank you!
D L whooop!!! Happy to know!! Thanks for your feedback!!
After unsoldering the speaker - the very thin wire that connects the drivers (and goes between the plastic cove at 3:00 in your video) pulled thru the plastic cover and came thru it's shield when I peeled it back. Do you know what gauge that wire is and where I could buy that wire? Thanks!
Oh crikey Mike... no idea, I'm sorry...
DUDE I bought replacement speaker for 18€ and I have followed your instruction for my 4y QC 25 with almost dead right speaker (cracking noise, or work some time) and it work. Regarding to the glue, I used a simple gel regular glue, just a little, and it's fine (at least for now) :D
Thanks a lot, that was quick with your video :D
Note that I accidentally destroy the little cable from the PCB to the speaker, I replace it with two simple electronic wire ^^ but it's fine :)
I am so happy that this video has helped you... I'm so glad you been able to repai your headphones!! Well done !!!
To put the drivers in ear cups like factory installation, only use 3M™ Yellow Super Weatherstrip and Gasket Adhesive (available in auto stores mostly).
For those of us who have hearing difficulties, the background music can make it impossible to hear the person speaking. One reason we need headphones to work!
Amazing... your not the only person to complain about background music... I believe I have learnt my lesson in later videos... thank you!!
This is amazing, thanks for making it!
Absolute pleasure!! I’m very happy you found it useful!!!
Thank you so much!
Happy to help :-) 😀
Thanks it helped me to change speaker for QC35. Glue was so strong that I damage the plastic inside but I don't care. I also had to remove the mini jack plug before (2 screw). I don't see the color of soldering in your video inside but anyway I guess I was lucky because it works like a charm!
Excellent... glad you got them fixed ;-)
Thanks from Germany 👍🍻
Ich bin sehr lustig fur dich
Thanks for the great video, somehow my QC25 is the special color version, with special glue, heat up very very very long time and end up the housing melts but the glue still doesnt, so can't get rid of the black cover without destroying it, did repair the speaker but can't reassemble normally with deformed housing.
Yeah sorry, they changed the glue 😕
Hi, and thanks for this great video. I have qc15 and testing the resistance on the two speakers, sure enough 100Kohms on the right one. So I'll go online and buy a new one, or two because I guess the other speaker will blow someday too. Two questions though: why does a speaker just blow 'out of the blue' like that ? I wasn't listening to anything, one day it was working, the next it wasn't.
Secondly, where can I get the replacement from, and be sure it's the same quality as the original?? Thanks again!
There are very fine wires in the speaker that fatigue over time. Normally just outside the warranty 😀
@@DubiousEngineering aah got it. Thanks!
Thank you for this video. My pair of QC25 broke after 3 years of daily almost daily usage. The right ear driver stopped working. After buying a 2 pcs replacement parts on ebay for just $5.89 USD incl. shipping i was able to fix them with this video. Bose asked for 155€ after claiming for full replacement. After some arguing they offered 75€. I have bought a still sealed pair of QC35 at a BlackFriday Sale. I am still wondering whether to keep them or switch to another Japanese brand.
I'm hearing similar things about the QC35s... perhaps use them until the warrantee expires... then sell them on!!
QC25 also often has wire broken where it connects to battery cover and the power switch is prone to fail. Still, overall very good headphones.
Good sounding, but just such a shame they seem to have a built in timed redundancy!
@@DubiousEngineering At least QC25 doesn't have built-in Li-ion battery that's designed to be NOT user replaceable.
Yes, same here. Thank you. Mine work fine again too. I used Patex 100 % all repair. Could not find copydex offline
Great to know there is an alternative... thanks for sharing!! :-)
To put the drivers in ear cups like factory installation, only use 3M™ Yellow Super Weatherstrip and Gasket Adhesive (available in auto stores mostly).
Hi, thanks for creating this video. Did you just use the numbers on the back of the driver to find a replacement? What is the glue your using? Thanks again.
I just searched on ebay for replacement bose headphone speaker
Awesome video with so much information swiftly shared. My headphones crackle on the left speaker when it swivels up and down. Any suggestions how to diagnose and repair that? I noticed you didn't remove the ear phones from their fixings and I wondered if that might be where the problem lay.
Ah - yes, that souunds like you may need to replace the internal cable... Thats going to be a fiddly job!!
@@DubiousEngineering thanks. I noticed that you didn't remove the phones from their holdings. I wouldn't know where to begin..
Dubious. Few days back my Bose 35!! Head phone got damaged in beach some water particals goes inside now not start
Sorry to hear mate... :-(
Never heard that detuned piano version of High Five before.
Hugh five or take five ? 🤔
@@DubiousEngineering Take five it is! You are right.
Thanks for this, I was able to repair my QC25! The new driver doesn't quite the same but then the new wasn't quiet the same (smaller coil and magnet) but maybe it will even up as it beds in.
Wish I'd known about this 2 years ago as I binned some QC15 I was given with the same issue :(
I'd hope the internal DSP compensates for any audio changes between the drivers... glad it was a useful video bud! All the best, Howard
How do you fix the foam ear padding that falls apart?
You can buy replacement pads on eBay ... do a search...
Thanks for the video and simple instructions!!! Work done, only claim is that the speakers sold on Ebay have less punch as they might be of less quality
I got mine from eBay and it was fine... but recently I had a report that someone had one that was quieter... so yes, I agree, watch out!
It work for me, thank you so much 🙏
Glad to hear that!
THank you Bro. Saved me some moneys...
Glad I could help - thanks for your feedback!!
Really helpful video, well narrated but annoying background music
Sorry about the music!
It would be great to see a teardown of the Bose A20 noise cancelling aviation headsets to see how they work and are assembled.
I'd love a set of those to play with :-)
I tried. You had some Rubber Cement holding the cover over the driver, mine (friend's QC25) was not "rubbery glue". I've worked with epoxy enough to know it when I see it, the one I was trying to repair was epoxied. To anybody else who tries, heat and prying may work, but acetone (nail polish remover) is faster, or vinegar. I used a plastic pry and Q-tips soaked in acetone. It came off. But after seeing the condition of the insides, I stopped the repair. These were for a friend, and they were falling apart as well as having the bad driver. I just bought him QC35
Well done for trying... yes, they changed the glue formulae once they figured people were repairing them to make it harder to repair, then they can get more money by new sales / trade in.
Just use some small blob of bostik blue tack instead of glue to put it in place. Just fixed mine working great.
Brilliant! Thanks Raj, for your useful comments! Glad things are working now!
THANKS!
You're welcome!
Do you have a reference as to where we can find the speaker to replace the broken one
Ebay! Thats where i got mine 5 years ago
11-07-2018 My Bose QC35 left speaker (where the wire connects) fades out until I tap the outside on that side then it comes back. Is that a speaker failure or a loose wire or what?
The external wires are quite sturdy... it’s likely to be the driver speaker... pop them apart and have a poke around with a multimeter....
Have you been able to fix them? I have EXACTLY the same with mine QC35, however mine right speaker seems to have the same. Since yesterday it completely stopped sadly enough..
@@gerbenvandooren6037 - - - - As I recall, I mailed back the old headphones to Bose when I ordered another pair which I have now. I got the blue tooth set to mate with my phone without a connecting wire. The work fine but the ear cushions don't last very long. I wear them 8 hours a night five days a week. Aftermarket cushions are available for way less money than what Bose charges. Note: If I had it to do all over again I would have bought the Bose headphones with the Alexa feature, even though it was more expensive. Cheers.
Hi, thanks for the video! Where can I get a replacement driver speaker?
eBay
Thanks, it helped me a lot
Great to know!! Thanks 🙏 for your kind words!!
how do we confirm whether the speaker or the circuit bord has failed? my QC15 L side working fine but R side suddenly stopped working
Have a look at AC voltage with a multimeter. If it's 200mV upwards, then the CCT is ok
Mine is the 35 II and stopped the right side via Bluetooth only. via cable both works. This means that is not the speaker right? any solution you could point?
Nei Rauni Santos correct - not the speaker it’s internal to the Bluetooth electronics I expect... sorry!!!
Thank you.
Hi, QC35 II showing a wired problem,
1) when its connected with wire switch is off then both ear are just working fine.
2) When its connected with wire switch is on then left ear is working fine but right ear some voice is not coming(human voice or similar frequency ) but music(instrument) are just working fine.
3) When it's connected with bluetooth the only left ear is working.
Could you please suggest what could be wrong here.
If I'm honest, this is too complicated for me! Sorry! Hopefully someone else may be able to help?!?
The noise cancelling feature doesn't work correctly without airtight enclosure for the speaker so applying clue here is not optional. You could use practically the weakest glue you can find that still allows airtight sealing.
Absolutely agreed 👍
what is the silver bit that is in front of the speaker (between speaker and L-R mesh cover? does it do anything?
I crikey I'd have to watch my old video again... maybe someone else can help? :--)
Thank you for the video.
Pleasure, I do hope it has helped! Thanks for your comments, here’s a little preview of a video coming up... ua-cam.com/video/wYAJzCo2UOc/v-deo.html
where did you buy the driver speakers and what kind of driver speaker need to be? Thanks you!!!
They are on eBay :-)
11-16-2018 Well I got out the hairdryer and got everything quite hot and the glue didn't get soft on the QC25 left speaker cover. I nearly melted the thing and punched a hole in the cover with the screwdriver (oops!) trying to pry it off. Apparently the glue they use now doesn't "melt" with heat - it may be permanent glue - not sure. Well, there goes $350 for a new pare of headphones. Can't get the glue to melt. Any suggestions?
q7winq7 Awww mate... I’m so sorry... I can’t believe they now made them unserviceable... that’s so mean!!! ..... very unfair!!
11-16-2018 @@DubiousEngineering - - - If they won't replace the phones as a quality control issue or warranty, I may just disassemble again and "cut off" the speaker cover (carefully) to access the speaker. Maybe a hot razor knife? Then if speaker is accessible, I may unsolder and check ohms of speaker and replace with new ones from Amazon.com. I think a pair is about $20 US dollars. Now I'm looking for their service dept. phone number for here in the US. Thanks for all your responses. I use these phones 7 hours a night in a factory. Can't do without listening to George Noory's program "Coast to Coast." Check it out.
I’ll have a look for coast to coast!! Thanks for keeping us all updated... people will want to hear more!!! :-)
q7winq7 push it out from inside with a screwdriver...worked for me
Dubious Engineering, thanks for such a clearly made video. I have a problem with my QC35 microphone - do you have any repair videos for this part? Or where one could find a replacement component? Cheers!!
I'm sorry, no I havent done anything on the mic. :-(
Thanks for your videos on fixing the QCs !
I've already fixed old QC2s with a replacement driver, now my QC25s have the same issue on the right side, sound cutting out intermittently .
Did you ever try a replacement speaker from China ?
They are dirt cheap, like 3 bucks a pair for 'Bose replacement speaker', and presumably the same ones that are sold for 15-20 $/Euros in the US and EU .
I bought mine on ebay... (the replacement speakers) and they work a treat!!
Hi, do you have a video for Bose QC3? I have similar issue with my headphone. Thanks.
Not yet, I'm sorry - no one has sent me any QC3s to repair!
@@DubiousEngineering I'm out of luck, thanks!
Is this something that typically needs to be done for both speakers or just one? I think I have the same problem and am hoping that one speaker will do it the trick. where to buy the parts?
Normally just the one. I got a replacement speaker on ebay. I believe its nly one company that makes the speakers over in china, so you can buy a cheap one! :-) My replacement was about £10 including delivery.
Thanks for your video.
My on-off switch doesn't work. Do you have any videos on that?
I’m sorry I don’t!
Are these intermittent issues also? I have a left switching off occasionally. I looked for a broken cable as this was the most obvious reason - but it doesn't seem to be the case...
Yes it can be intermittent
dear gentlemens somebody can tell me where can i found the replace parts? Thanks! This video is GREAT!!
eBay my friend... read some of the comments here
Excellent video! thank you very much my friend
Pleasure!! Hope it help!! :-). Thanks 🙏
Is this a common problem with the qc15 or is there another problem that can occur to cause the loss of hearing in one side. Also what type of driver speaker is reccommened for replacing an old one.
I got my replacement speaker from ebay.
Very clear instructions with excellent images. Great work, Dubious.
I have the Bose QC15 headphones. The little spring on the negative battery contact broke off. I'm not sure how to repair it. Perhaps it can be soldered on, but I have no idea how to remove the hinged plastic battery 'door' to allow access with a soldering iron. I imagine this piece is easily broken.
Any suggestions? Thanks!
Wow... I’m so sorry... I no longer have the qc 15 ... if I did I’d have a look... perhaps ifixit on google may be able to help??
I have the Bose sound link Bluetooth wireless headphones. I need to fix the headphone jack connector will this video do the same thing for my Bose headphones
this is about the speaker problem, not the jack
My 35 are working but the left channel has an occasional Grumble when moved is that a speaker breaking or another fault?
That sounds like a different fault, I'm sorry!
sorry sir, where can i get the parts? i have qc 35, it's is not available here, it is possible to use qc 25 parts? pls advice
Check eBay
Do you have a video about changing the rechargeable battery in the AE2 BOSE bluetooth headphones?
awww sorry I don’t... send me your headphones and some money... :-).
Where can I buy replacement speaker fo the QC35ii? Will the noise cancelling work well after the repair?
EBay…. That’s what I did
Hi. I have a issue with My QC35 the Bluetooth white (LED light) still on when I turn off the headset any help? . Best regards
That’s weird! Sorry no idea why…
Heyy, i have the qc 45 ll and the noise cancellation isnt working as it used too (it seems to be stuck on low noise cancelling) I tried everything popping the ear pads back on, properly, software update, reboots... idkklk what to do !! Please help
sounds like a firmware upgrade (or maybe downgrade) could help
Hi, first of all thanks a lot for the video, it is really helpful ! I'm about to order a new speaker to proceed with the fix but I have one doubt : on mine, the speaker still emit sounds when noise cancelling is off. It's only when noise cancelling is on that it stops working. Does this mean that the speaker is, in fact, not at fault and it might be something else ? Or is it normal that it still emits sound when power off ? Thanks a lot !
you may be right... sounds like you have a problem with the pcb rather than the speaker if the speaker works with power off....
Fuck yeah man, hellova guide. Appreciate ya.
Very glad it was helpful!
I have QC 35, few months back cracking sound started in right side speaker which disappears for a while after mild tapping on it. Is there any issue with the speaker or any wire has been broken? Pls suggest as no technician is ready to touch it, and I’m trying to fix it myself
Replace the speaker
@@DubiousEngineering thanks! Can you suggest any ?
I dropped my QC 35 ii’s yesterday & now they won’t power on. Any thoughts on a fix would be greatly appreciated!
Oh dear... that sucks... best return them if in warranty... if not, best open them!!!
@@DubiousEngineering out of warranty so Bose will be happy to exchange my $200 and the current pair for a new pair, lol, so I figure I might as well try a diy repair before I do that. Was curious if you knew of anything less obvious than a wire coming loose, like a part that may be susceptible to shock from a fall?
Where do you buy the speaker driver? What model is it?
EBay
Interesting video.... It would also be interesting to get the name & model of the replacement speaker..... Plus, where to buy such an item.
I got mine on eBay :-)
@@DubiousEngineering Thanks.... what was the search name did you put into eBay to find the item?
