- This video explains the repairing process of a defective power button on the Sony WH-CH700N wireless noise cancelling headphones.
In this case the internal switch, which is mounted on the motherboard, fell apart and was no longer functioning.
By removing the remaining parts of the old switch and replacing it with a new. one, the headphones started working again and it is no problem now to turn them on again.
This is the replacement switch, which was used in this video:

@@maylonkirby5455 Hi, it is called Flux. This is necessary to create a proper bond between the switch and the PCB.
I prefer using the type of flux that comes in a syringe, like this one: amzn.to/3impWF4
But it also comes in many other forms (which are often cheaper).
You are a wizard for finding this part hahaha, just saved me a new set of headphones. Nobody could fix this for me at electronic stores. Been looking for a video like this for over a year! Thanks man!
Glad to hear 🙂. Thank you for your feedback! 👍
Another tip that I just learned, which is an amazing help if you don't have a soldering gun and can't find the parts, is that the CH007N headphones have NFC capability, so if you have a phone that's also NFC enabled, you can turn on the sony headphones remotely with your phone. It works on iPhone 7 and later, and plenty of other devices.
OMFG it worked!! Tyyy so much for this, now I can finally listen wirefree again :D So simple and yet magical, I just searched NFC on my samsung s9 and then put my phone on top of the left part of my headphone and it turned on! Thanks so much! MANY HUGS
@@camillafors4678 Ha. I was just as stoked when I found out about it as well.
is there any similar way to get it to go to pairing mode so that i can pair my pc with it?
@@mik4336 Good question, and unfortunately I don't have an answer. It's a shame that entering pairing mode uses the power button as well. When you use NFC to turn it on, it doesn't automatically pair with the device used to turn it on, so it does at least allow you to pair other devices. But I don't know about pairing mode. I wonder if just holding the NFC device to the headphones for an extra 5-10 seconds would have the same effect as holding down the power button? Worth testing it out.
I can't do it. NFC enabled and bluetooth connecting, but then it's suddenly not possible???
Thanks for helping me out! you made my day! (actually for a month)
yo the craziest thing happened. so my headhones werent working for a year now and i had just been using the nfc tag to connect them with my phone, so i saw your vid and decided to check out if it was a similar problem but everything was normal, nothing was broken or out of place so i just screwed the motherboard back in and built them in again and just decided to give it up. then i tried to press the on/off button AND IT WAS WORKING??? I DONT GET IT but im proud
Thanks a lot, you saved my day (actually, about half a year)
Bro you just saved my headphones, thank you very very much
Glad to hear! Thank you for your feedback 👍
Would you be able to a video how to do replace the drivers? After dropping my headphones, I get no sound from the right side.
Excellent! I guess that will fix the problem on my headphones as well. Thanks!
OH MY GOD IT WORRRKEEDDD. U SAVED MY HEADLHONEEEEJWENSMS. THANK YOU THANK YOU THANK YOU FOR EXISSSTINGGGG
I got a refurbished pair of these just now and the left side isn’t working. Don’t know where to start (I took them apart, and got sound to come out of that side for a few seconds before it hit a heavy bass note and cut out again).
How long do you heat the switch before it comes off? I was heating it for a while and the switch wouldn't come off. Ended up melting part of the headphone from under the motherboard. Smh..
This just happened to my pair. However, my phone was near the headphones and it picked up the NFC and I was able to connect the bluetooth! Very odd!
Hello, I press the power button, but it turns on. When I release the button, it turns off, but if I press the button continuously, it stays on As soon as I release the button, it turns off again What is the problem
Not working
Any other method to turn it on?
My headphone switches on but getting no voice guide nor any sound. Can you please help?
Hi can I just ask was your power button loose/faulty???
Hi, from the outside it looked normal. But internally the button completely disintegrated.
I have the same pair of headphones. but I got a different problem. They can be turned off and on just fine, but when I plug a micro-usb cable for charging, it never charges. I tried different cables, different USB ports and also tried a known working headphones with the same port / USB cable and they charge. I also noticed that if they are turned on and a cable is connected, everything stops. I am suspecting a shorted motherboard - what do you think?
Quite possibly the micro usb port on the headphones.....Type B are notorious for breaking pins- distorting etc. Try squeezing the top and bottom of the plug together with some needle nose pliers.
There are two types of switches so idk which one I have to choose. The "Cut Tape" or "Digi-Reel"?
The Digi-Reel is for assembly line manufacturing.
You want the cut-tape. 👍
Thx a lot man.
Are they replacement pads you are using there? Where did you get those?
Yes, these are replacements. I have made a different video about that.
Here’s the link to the ear pads: amzn.to/3qhXbuW
I don’t see where to order the part
what is the size of the screw ?
Thanks for this. I tried this and was able to solder the switch to the board. However, suddenly at the end of the process the bluetooth began pairing and the headphones then said "power off." The headphones will not power back on now. Any idea what I did wrong or if it can be fixed?
Sorry, I don’t know what the issue may be.
When you close the power-switch circuit with a wire, do the headphones turn on then?
@@MegaSafetyFirst Sorry, I'm not sure how to do that. I wonder if maybe I used too much solder or accidentally nicked the switch with the solder tip.
So I pulled the wires out that connects the speaker. Where do they go can you make a video on how to re attach them :(
Hi, I’ll probably won’t get to making a video like that for a while.
There should be a row of wires soldered on the backside of the board. The wires of the speaker are part of that row.
Sorry, that I can’t be more helpful at the moment.
@@MegaSafetyFirst ok thank you and how about getting new screws these buggers are tiny and I lost one. Also thank you so much this was helpful
Hi..I have the wh -1000xm4 .they will not power off.they stay powered up until the battery goes dead..recharge remove charger and they power up…no matter what I try they will not power off
Could you do this with the Sony Wh-1000XM3?
I don’t have that model. But it might be similar to this.
@@MegaSafetyFirst thanks, I will try to find a solution by following your steps, hope it works. I don't want to pay another $350 bucks for a new pair
Well done! Thank you.
My power button is jammed? Is this the same thing?
That is possible. It should only take a few minutes to check if the switch inside is broken or not.
How do I do this without all the equipment
I’d ask at a phone repair shop how much they charge to do this job.
@@MegaSafetyFirst ok
Can i comment in german? I thought i've heard a little german accent :D...
Ich habe ein Headset von Clam. Da kann ich nicht einfach das Ohrpolster entfernen... was tun?
Bravo!
Welp,for is folks that can't do this we gotta but new headphones lol
That is unfortunate when you don’t know anyone who can do these kinds of repairs.
You could try to sell them as defective on eBay and at least get a for $$ for them.
This headphone is a crap. Don't last long. Thanks for the info
0.27 € for the part is nice. 20€ of shipping not so nice :(. Bye headphones...
The store is shipping from the US.
There might be a company selling the same part closer to you?
@@MegaSafetyFirst Thanks for your response! I've tried several, all between 18-20 € shipping, except RS Components. Although the minimum amount of switches to purchase there is 20, the shipping is 5 €, so with taxes included the order is around 12 €. Not bad, but the headphones owner has to decide xD. It's a shame the switch broke due to a fall from very low height. I've still got the upper parts, but it seems impossible to join them back together...
Sony headphones are garbage.
