It works! You have saved me 250$, thanks a bunch.

Thank you so much!! 2 pair (3 earbuds) repaired yesterday based on your video... I had a pair, than one of the earbuds went off, so I got another pair. Yesterday I noticed that the new right side stopped working also, so I googled it and found your video. When I got home, I thought I'd try the method on the old one, but by then both old earbuds were off. So now I have both pair repaired :) Sennheiser should warn all customers with big red letters not to let the buds run down...

I hope you see my comment. This worked for my R earbud, but it lost touche control and now I can't pair my headphones. Please help 🙏

I wake the device after 2-3 days its again happen. I did factory reset as well any reccomendations appreciated.

It didnt work for my left earbud…the battery charge is at 0.2 volt which probably means its broken, cannot jumpstart it anymore. If I try with the method you demonstrate here, then the box goes blinking red after 2 secs which means short circuit or battery broken. I would also advise against removing the battery completely like demonstrated here, just remove the cover only and maybe the little connector and try it that way. Other people here commented the same.

Where can you buy the devices go check voltage and jump start the battery. I just see people fixing it but i dont have the tools.

I wish there was a version with home tools, i saw something with batteries. Not sure if it works

Sennheiser better than Sony .

Thanks to your video I solved it, the right earphone was no longer charging, unlike the video I improvised with a cable to charge the Xiaomi smartband, the contacts matched those of the earphone battery so I tried, the first test failed by heating the battery but it continued not to charge and work. On the second attempt I noticed some small shocks and I feared I had reversed the polarity so I tried again by reversing the side and after this attempt the earphone started charging correctly again, thank you very much, you were a great help 😉🙏👏💪❤

So stupid for Sennheiser not to identify this problem in thr dev phase. What is their qualification and & hardware teams doing ?

Hello, any help here. Right one woke up with 2.7V but Left one still at 3.10 V and doesnt up or down voltage but doesnt wake up as well... Thanks in advance.

Is it possible to reset the voltage using croco wires on the case and pin the output directly to the both embedded pins without opening the bud ? Just to force the voltage to be up again ? I would like to avoid to open the bud Thanks!

Tried this several times but just not working for me. The buds just not taking any charge at all. Its my second pair so theyre going straight in the bin.

This is worked for me too! However I need to do same thing once a week, it happens again.

Amazing, mine is working perfectly now, tanks alot! P.S.: I didn't even need to remove the last part of the earbud, just opened it once

Worked like a charm. Thank you brother.

Worked Perfectly Thanks!!!

Thanks a lot! I tried it earlier and now it is working perfectly!

I tried charging it for a while but the voltages won't increase?

Replaced 5 pairs on warranty for this problem. Just got the M4.I hope the problem was solved with this one.

Thanks, I did it also and it works well to recover the battery but unfortunately I have no more sound on this earbud and I don't understand why...I tried the reset to factory but it doesn't change anything !!😩 Can you help me ?

This fixed mine, thank you very much for posting I would have never thought of doing this 🤝

What a piece of ...t these earbuds. I love the sound but such design flaw is unacceptable

This works! Very clear and easy with a cheap multimeter. Many thanks!

Amazing! It does works. But one thing to mention you don’t need to separate the main part. Just took the cover off then you can jump charge from there. Great tips! Thank you!

Wish you made this video sooner. I warranty exchanged my MTW3 four times within a year, and on the last time, I wrote a long letter to Sennheiser saying I gave up on these buds. I asked nicely to exchange them for the Momentum 4 headphones and surprisingly they agreed. I'm considering getting the MTW4 as apparently, they fixed the battery issue.

It worked for me and now my earbuds are working again!!! Thank you very much for this!!! The earbud batteries are not charging up to 100%, they remain around 80% to 70%, but I guess this is another problem. Such a shame that this phones got this huge problem! I enjoy their sound, but this unreliability made me switch to Airpods Pro 2.

Any advice on Sennheiser Momentum TW2 wireless headphone, left ear bud only works when in an elevator or on a plane, or if my phone is 5cm away from it, some sort of interference issue? Any help would be amazing

Fix my problem earphones thanks very much.

I will never purchase another Sennheiser, i have no time for this, wasted my money

what are the cables called and where do I buy them?

I want to thank you, you helped me with repairing my buds :3

@JINZZEWANG-nz8bc help me. The moment I connect the cable to the earphone, the case start blinking red. I have tried changing the - / +, just in case I got it wrong, but still the same. Do you know why? Pleaseee

I had this very issue and followed the video. Worked like a charm. Momentum 3's working again like there was never an issue.

thank you so much!!! gonna do this tomorrow!! those sennheiser "consumer support" should have this video on the play always during their daily meeting
