How to fix BOSE QC15 Headphone

How to fix the power supply issue in QC15 Bose headphone...

[@wunne1]

Thank you some much! I fixed mine slightly differently (also, it was the positive cable that had a damage somewhere inside, negative was still great). But your video helped me a lot. Liked that you actually show how you find the rights spots to fix with the multimeter. Two thumbs up!

[@johnharrisjr.351]

Thankyou for this. I did this operation to my QC15 today (five years after you published this). They'd been dead in my nightstand for several years, but now I'm using them again after a beer and some solder fumes.

[@dukeyin1111]

Can't believe I fixed it. What... THANKS!!! (It was the ground wire to the battery got rotten due to battery acid leak)

[@pheroztengra2821]

That a marvelous diagnosis - In my case the positive wire fine, but the ground wire where it connects to the battery door was broken due to battery acid leak. I had removed the door to find the corrosion,. I had to take an extremely thin wire and pocked a hole below the battery door pivot point, and then rerouted the wire on the PC board to be soldered to the mother board on connection "2". Very grateful for ;your help.

[@Brady8812]

This was very very helpful. Had one today where the ground wire was corroded inside the battery terminal. Used your technique now have a happy customer!

[@batterybala7791]

Happy to know Brady.. 🙂

[@kurtwebb420]

Great step by step directions! I needed to change the ground wire that detached from the battery door. By detailing where the ground and power connection points are on the board, and how to reroute the wires, I was able to fix my headphones. Thank you very much!

[@paulmohr8719]

Excellent instruction. The negative wire on my QC15s was broken just like in your video and with your help was a straightforward repair. Thankyou very much!

[@batterybala7791]

Good to know !!

[@corangerc]

sweet..Fixed it..Just had to replace the neg side wire ..Had to drill a small hole for new wire and soldered it to board and plug end. Thankyou...Saved some $ I dont have..;)

[@chadbersche]

Thanks much for this. My QC-2 headphones quit on a recent trip, and I noticed the wire inside the battery compartment had come loose. I was pretty sure I'd be able to fix it, but this helped me know what went where, and the best approach. The QC-2 is even more obtuse, since there's no connection points inside the ear cup. Saved me from buying a new set, and they're once again working, with a marginally thicker wire, to hopefully hold up to the opening/closing of the door for a few more years.

[@edburns00]

I was shocked I got it working again! This was helpful to me, but I made the following changes: 1. I used a much bigger gauge copper wire, because that's what I had on hand. 2. Because the wire was thicker, I drilled a hole in the battery cover and routed the wire through the hole where the existing wire goes up and over inside the headband. This also required me to snip out some space in the silvery plastic cover to accommodate the thicker wire. This means I have a bit of wire exposed. The soldering was such a challenge. I had no confidence it actually work since I suspected I introduced a short with my clumsy soldering.

[@thezenwizard]

Thank you for this - mine suddenly died and I suspected that the negative wire had broken. Using this I managed to get it all sorted fairly swiftly!

[@driftwood9421]

Excellent explanation and a very detailed video. I've now repaired mine and I can now listen in peace! Thank you very much.

[@pauladams4435]

I fixed my friends headphones with this great tutorial. Now he thinks that I'm the dogs bollocks.. Thanks very much sir.

[@eurodj101]

I just found a wire close enough to the same gauge as the stock one and replaced it but left a bit more slack.....pretty much everything is as before except I used a gray wire instead of black.....thanks for the video as it pretty much guided me to the problem though I had taken it apart before and tested continuity...this is invaluable

[@workingTchr]

Looking forward getting my Bose phones working again. Thanks for the video. But I think that I'll try and splice into the wire(s) coming off the PC board rather than risking damage by soldering directly onto it. And, hopefully, it'll just be one (+ or -) that I have to fix. (I'm half wondering if Bose would still repair it if I messed it up trying to fix it...)

[@ianmain8470]

Good explanation of how to fix the faulty battery wire. Just study carefully where he drills the holes to pull the new wire through.

[@davidtempler9593]

Despite that only the wire from the battery door was bad, I replaced both. Probably didn't need to but its done. Had to drill out the existing hole to allow room for 2 wires to come through to the circuit board. Not a perfect job but they work now and I don't need to replace them.

[@korbe4799]

Great video,. I was able to mix my QC15 wuth this. Negative cable was disconnected from circuit board. When I was soldering it back the soldering point separated. I used the upper one (speaker) negative point and its working.

[@marioboniol1892]

Hello folks, my Bose QuietComfort 3 has left speaker not working, can someone please show me how to open the cover? I've been searching the net for instructions but i can't find any. Thanks.

[@jamestaylor5951]

what wire type are you using? im new to this kind of thing but have my own pair that id like to repair

[@emule9994]

Hello, nice video! From 5:11 to 5:18 you are gluing some silver colored metal part. Do you know what this piece is for? and if it is important to put it exactly in the right shape and location as before. Thanks in advance

[@batterybala7791]

No need...it's works well without the silver foil shield

[@nizer3]

thank you so much. I found the negative terminal buy following the black wire back. It had separated from the negative spring. You just saved me $300 dollars. :-) Bose talks to you like you are an idiot and there is NO WAY to fix them. It took me 15 minutes.

[@ericoppel5698]

It would be great to see a teardown of the Bose A20 noise cancelling aviation headsets to see how they work and are assembled.

[@leonardojoaquim8262]

One more here that you saved, sir!!!!! Thanks

[@tec4303]

There is an even better way to route the negative wire: you can feed it through an existing opening between the pcb and the battery compartment. The opening is at the top of the headphones. The new wire can then just be placed on top of the pcb to rout it to the solder joint.

[@mattsutube]

The hole you're referring to is the screw-hole for the top half of the plastic cover. ( unless I missed something) I did use it... the top cover is now held in place Securely with a small piece of black tape at the top. Good enough, headphones sound awesome again. ..

[@sassydawg19]

Took a while but managed to follow your instructions and had success :) Re-routing the wires was a bit of a hassle as was trying to resolder on such a tiny scale. Your suggestion to cut existing wires and resolder to the stubs is clearly the way to go. I desoldered at the circuit board. So MY fault :) Thanks !!

[@jonathangarza3078]

Damn!! a really helpful video, I haven't gotten mine to work yet because the pair that I bought used were probably a set used for testing in a shop, the main audio cable was screwed to the shell of the headphones and was a bit strange, at the end of the cable it used the normal 3.5mm jack and another one for I guess it was for power which I dont know if Bose actually made those cables for sale, the soldering joints inside were the battery should connect to weren't soldered and there were no contacts for the battery neither. Have you tested yours with a normal 3 pole cable or do you have to use the proprietary cable to make them work? I just want them fixed as soon as possible and my only solution is this one or to take out the circuit completely and solder the wires directly to the headphone drivers.

[@FilmmakerIdbox]

I have an issue with my QC15, the same model as in the video. I had left the battery inside for a long time and apparently it leaked. I did clean the battery compartment but after I switched it on, it gives a tunning signal. Please help.

[@fabricebias9117]

Salut j’ai réussi à réparer mon casque. Merci et bon courage.

[@mdhdhair]

Your the man!! It worked!!!! Thank you! Subscribed from San Diego.

[@shaileshshrestha9725]

Got my headphone self repaired. Thx.

[@raytannous7633]

Thank you. My negative was rusted because of the battery acid

[@PeterObermeier]

Thank you very much! Without your video I could not repair my defect headphone! 😀😀😀👍🏼👍🏼👍🏼

[@joshuathompson4568]

Thanks a lot. This was a great help.

[@vhh1573]

do you have videos on fixing turn-on switch. Thanks

[@batterybala7791]

Sorry.. I don't have anything more on this..

[@nataliaoc2877]

Thanks for the video!

[@deepak2268]

Help please. I have a wired quiet comfort 15 , battery inside had leaked. Which i removed and cleaned , after which am getting a beeping sound , i tried removing the ear pads , cleaned by air blowing ..still there

[@rymdskrotet]

Theres some sort of "glitch" on my power switch. I hardly touches it and the headphones is turning off and on. Not sure how this is fixed?

[@kylemiller6639]

i'm confused about the + lead to the tiny rectangular circuit board on the inside side of the plastic housing at the bottom of the battery well. my + wire seems intact w the wire gong into a small cylinder (? ferrite noise filter?) that is glued to the plastic to keep it stationary then soldered to the END solder point of the circuit board. at 2:21 you show that circuit board but it looks like you already pulled out that small cylinder and + lead but then you attach it to the MIDDLE solder point, not the end point. any clarification? thx much to anyone who can explain.

[@hoapham7210]

Thank you very much for taking the time to video this...I did exactly as you recommended and it works now...thanks again...

[@TinyTavino]

Great to know ! Happy this video helped

[@RaizySabel]

Thank you!!! I did my wire somewhat differently but it's working now!! Amazing!

[@tec4303]

I'm not sure if it is a good idea to reroute the negative wire like this because of sound isolation. You crated a path between the pcb chamber and the inside of the headphones. I would add a drop of glue to the places where the wire goes through the plastic to make sure that the noise canceling is not affected.

[@TinyTavino]

Ground wire is taken to the solder point itself and not at speaker ground. Atleast no difference on noise cancellation felt after that... Its as same as before.

[@cosmicaug]

What other modes of failure does this device have? Mine has just started to randomly click & then the sound shuts off. However, it is clearly not a power issue because the power remains on (and I still hear an electronic "muffling" -I don't know what else to call it). That is, it's a bilateral total sound reproduction failure without power loss.

[@cosmicaug]

Never mind. I think it is the power issue. Shouldn't be too bad of a fix, then.

[@cosmicaug]

It's actually an issue with the wiring between the two sides. Presumably, it's shorting out in places where the wire enamel has worn out. I can reproduce it by putting stress on the joints. I can see that the cabling has worn in several areas. I do not know where I would source that cabling between the two sides. I am seeing blue enameled, green enameled, red enameled & copper. I thought that I might be able to sacrifice the cable that connects to an audio source (the input cable) but that seems to only have 3 connectors (a blue, a red and a copper).

[@jolifunyoutuber9588]

Thanks a lot for this tips to repair.

[@bombiuxx559]

Osea conecto directo la batería? Me venden unos igual y no encienden

[@redfoxxxredfoxxx]

Grazie di cuore per il tuo video, ha salvato le mie cuffie. ...da Napoli. Massimo

[@rfhino]

It really worked. Thank you.

[@cottontail888]

What gauge is that wire? and what kind of glue/gum did you use??

[@steveswoodworking2504]

For something like this, a fairly small wire maybe 24 or 26 gauge works well. I really like the silicone covered wires, such as this: amzn.to/2ObwqpY Of course, the gauge doesn't matter that much, if you have some wire already that is close enough, just use that. But if you don't have any wire, the pack of 6 colors of 26 gauge wire is great to have around.

[@evandroalvarenga8539]

Thanks!!! Realy helpful!!!!

Excellent Video. Very useful and well Explained. Thanks

[@batterybala7791]

Thanks...

[@cs20m]

Does anyone have a reference to original speaker part used by Bose in the QC15 ?

[@ralphe5842]

left a battery in too long will try to fix this way thanks

[@hayman122]

the npise canceling effect works and i see the green light but when i plug in the headphones i get no sound on diff devices

[@srikanthiyer7285]

Hi... Can you help me with battery corrosion? I had left battery in my qc15 and there was battery leakage and now headphones dont work.

[@TinyTavino]

Hi, use thinner or nail polish remover to clean the PCB and the battery holder.. it will be alright

[@srikanthiyer7285]

@@TinyTavino thank you. Let me try this.

[@juancamiloleonsarmiento3656]

muy bien !!!!!!!!! funciono !!!!!

[@itswiddow5039]

Okay. What the fuck is wrong with youtube and this video. It doesnt load for me like at all.

[@Changbastard]

I was able to fix my headphones from this tutorial. I’m so disappointed that Bose choose to use a very thin and cheap wire to lessen the life of these headphones. This of course was after I had to replace the headband and ear cushions.

[@batterybala7791]

Happy to know !
