- Опубликовано: 17 июл 2024
- This is the teardown video of the JBL TUNE750BTnc wireless Bluetooth headphones. We are taking a look inside and show you exactly how to open these headphones while keeping them intact and still being able to use them afterwards.
The left ear cup holds the battery. The right ear cup contains the major PCB, with the micro-USB charging port, the button switches and the four LEDs.

I was about to disassemble my JBLs because my battery would stop charging after 30 seconds. Apparently, watching the video next to my headphones scared them enough to work again, so thank you for that 😂
For anyone having the problem where the headset no longer turns on but works via wired, just teardown the small part of the left earcup, inside is the battery as shown in 2:21 and then just make sure the big wire is properly connected and fully in there, then it should work.
i swear on anything i love you just saved my jbl’s as SOON AS WE SPEAK bro preciate yu
@@_dvidabi7116 No problem hehe, glad it worked for you too :)
This helped alot, mine stopped working & I disconnected the battery and reconnected and it worked immediately 😁🙏🏻
Thank you! I've solved a tiny broken part making noise on every step when walking because I knew how to open it up. I found this video when searching for JBL 760NC. it wasn't the first result so you may want to add it in the tags.
THANK YOU SO MUCH THE BATTERY CABLE WAS DISCONNECTED SO I CONNECTED IT!!BEEN A YEAR 😭
Thanks to you, I fixed my headphones. I opened the left earphone and saw a loose connector there.🙏
I bought a pair of these phones just yesterday, October 20, '20. With a special senior citizen's discount the price dropped from NZ$239 down to NZ156. I have only used the phones off and on over 24 hour, so far. Based on price and quality I rate these, my first BT, phones highly. However, watching you "disassemble" the phones was somewhat akin to watching a surgeon taking out my appendix and providing a commentary as he did so.
It is an interesting video despite my wincing as you proceeded with the stripdown. Now I know what's under da hood. Thanks.
mahn u seriously saved my life..my headphone fell of and it was not turning on at all .the connector was loose ..now its working perfectly fine..
how did u do ?
Thank you so much! Thanks to your video, I could repair my headphones by reconnecting the battery!
Thank you. Your video helped me to open headphone to fix the left side that wasn't working
Glad to hear 👍. Thank you for your feedback!
Thank you vry mch just fixed my jbl tune 760 nc loose charging cable..you are a life saver
So many thanks! It worked!!!
THIS FIXED MY HEADPHONES THAT WOULDN'T CHARGE THANK YOU! If your headphones won't charge and the charging light only stays on for a couple of seconds before shutting off I'd recommend opening up the battery department and replug the battery, as there's a high likelyhood that the battery cable got a little loose and just needs a bit of motivation^^
Funktioniert auch bei den Tune 720bt, super Video hab es grade ausprobiert
Thank you very much.❤
loved it
Hey, thank you for the video, the fake leather on my R side is coming off, the inside part of the leather, I can open it this way and just use super glue it will be fine?
Dang it mine just broke today i was about to drop them and then bluetooth pairing mode stopped working. So i ofc did the manly thing and decided to take them apart. Anyway turned out it was the on and off button that had come loose i got it to work with it placed with a tweezer but sadly the repair failed because the connectors snapped off. But taking them apart was a breeze thanks to your video :) they lasted about 3 years and i have been using them probably 16 hour a day almost every day. and other than a stupid bluetooth adapter in my pc they have been working almost flawlessly so i think i got my money's worth
Love your vids. ❤ Will there be a jbl live 650btnc? Also curious to see what is the inside of the jbl live 650
Thank you! 🙏
I’m not sure I’ll get to the live 650 yet, but it is on my list for future videos 🙂
Rumour says it's a hidden portal to the other side of the galaxy, so DO NOT tamper.
Heads up. The small wire can be loosened to help prevent accidental damage
THX i fix my left headphone by myself!!!
bro i literally came here to know how to remove the earpad well guess what my left earpad worked
Can you make a video to remove the headband cushion like de-assemble the band part.. cause it's wearing off and I want to put new cushion if it's possible
Hi i brought this headphone after one year the Bluetooth option stop working now left ear also stop working. unfortunately warranty period is over, is there any way to fix that bro?
Is there a way to disasseble the hinges and headband without disconnecting any cables?
Mu buena muestra, se me rompio el boton del volumen. Podrias mostrar mas esa parte?

Which are better the jbl tune 750btnc or the jbl live 650btnc?
Hello everyone! Before all disassemble try to disconnect battery and connect again. I had a problem with charging. After reconnection my problem was solved.
i have the exact ones and my right side isn’t working, i haven’t dropped it and it’s done this before but now it’s done it again and it sucks can you help me please
I'm also having problems on the right side of the phone... did you fix it?
Thank you man. You sre the best ❤
Anybody had issues with the noise cancelling? After a while mine insn't working like in the beguinning.
Thanks
Thanks to you I didn't break these headphones! White cable has desoldered in my headphones - responsible for minus audio signal to the left earphone. The damage was probably caused by a fall to the floor. The quality of the solder joints is dramatic + lead free tin - shame on JBL!
Same happened here! Hope I can repair them
Can you show what's missing at 5:45 ? Because that part is where the board comes out, and is almost impossible without damaging the it.
there are 2 screws which are not in the video in the middle of the board
thank you
4:54 what's that white socket thing on the pcb? is it for a digital interface of some kind?
Yes, probably a serial line for programming.
Bro my jbl 750 btnc bass is cracking while i turn on anc mode and sometimes while i use it without anc mode the left side of the headphones dont work only sometimes please help me bro and yeah these are costly too please make a video and reply me
My left side stopped working
How can I fix it
Servus brauch deine Hilfe zum Video mit dem Innenraumluftfilter bitte
I dropped my headphones in a pond and it still turns on /off but it wont bluetooth pair anymore.
Do you think it is possible to do this without any visible damage? My micro-usb is probably damaged and I really want to repair it, preferably without damaging the headphones.
I think it is possible to do this without seeing any damage afterwards. This model is very easy to disassemble.
The most difficult part is probably removing the ear pads.
@@MegaSafetyFirst Alright, good to know. Thank you for the quick response! I'll definitely rewatch this video a few times before attempting the surgery.
I think my USB port damaged as well. Have you manage to repair it?
@@samral1515 I'm afraid not. I ended up just sending it back and I even got a replacement. I didn't really want to do this, but it did seem like the best option. I'm lucky, since my warranty was still valid.
Good luck!
@@Iraijus thx for helping
I have this one but now it's left side isn't working ,can any help me to fix it .
This might be the fix for your problem:

is it possible to replace the top foam?
I’ve seen the top foam as a replacement part anywhere.
You might have to fabricate one yourself and glue it on.
How is the quality of hinges swivel?
Poop
MY headphone's power button is kinda stuck and it wont click, so what can i do about it?
When you feel comfortable with it, you could try to disassemble the ear up and check what is making them stuck.
There might be some dirt in there that prevents the button from moving freely.
If you have tried it can you please tell me if it works? I've the same issue.
I side when connected with Bluetooth does not work, but with cable both side works. What is d problem here?
Sorry, I don’t know how to fix this problem. I haven’t seen this issue myself yet.
Have you found a solution? I also have this problem and don't know how to fix it.
@@kasiarech7697 did you find a solution? i have the same problem
@@krzysztofzioko4694 I didn't but somehow it started working properly on its own. So I have no idea where the problem was.
@@kasiarech7697 I'm also having problems on the right side of the phone... stops working and starts working again... i guess its some sensor or cable
You didnt show that you unscrew the screw on the right Platine. I almost break it, because i thougt i can remove it like you Do it in your Video. Be carefull guys.
I was not that lucky. I tried to fix my dead left earcup but managed to break the power button and now they’re completely useless, hah.
this vid casually saved me 70 bucks
