@@markjordan4593 actually this can happen with li-ion batteries. I had restored two batteries by using an external charger, granted, it was a long time ago, but the general idea is that even if they report they are empty, there is still some charge left, to protect the battery, once that charge is lost, you need to "jump start it", this might degrade it.

Sennheiser already claimed that there was an issue with their battery supplier, that is why they are exchanging defective ones with MTW4, if yours is dead and you still under warranty.
Man, what a life saver you are! Thanks a lot! My second pair (first one was returned for the same reason) stopped working last week and I've moved to a country where the warranty is only available for products bought locally. This fixed it completely! Let's just hope it won't drain out again.
Thank you Alex! AGAIN! My L earbud failed last year and I fixed it using your video instructions. Now my R earbud just failed. Fixed it again with your video. You are brilliant!!
My earbuds is 100% FIXED NOW!!🎉🎉🎉 Thank you for this tutorial and to my cousin who have the guts and the right tools that made this possible. We should use this LINK/Tutorial as a reponse to every reddit post relating to this matter. Bravoo!!! 😊
I came across this and thought there was no way it would work... then I read all the comments and decided to give it a shot. Took a bit to disassemble the earbud, but heat gun on low setting definitely helped loosen the glue. I didn't have the standalone holder for 3 AA batteries, so I just used something I had with 2 AAs, loosely connected two copper wires I had to the ends of the batteries and to the connector ends of my multimeter (black to negative, red to positive), then held the leads where they are shown in the video for 3 minutes. Put it back together and problem solved! Thank you so much for this!
This video was extremely helpful! I travel for a living and Sennheiser wouldn't help me unless I went back to the country I bought them in. After watching this video and some help of my husband both earbuds work again after a month of being broken. Very Greatful for people like you who post very helpful and educational content!

God, man, ty a lot, today mortyng my right ear don't work, but I had everything to solve this problem, 5 mins and Work!!! Bro love you, I read the forums and knew about this problem, but I didn’t have a solution, thank you thank you thank you bro that your latest video saved me from disappointment
hey, thanks a ton for this video! i was about to give up on my sennheisers, but your tutorial totally saved them. appreciate the clear and easy-to-follow instructions. You’re a true hero!🍻🤜🤛
Thats Amazing. You saved my sennheiser with this video. Just use adapter with multiple voltage with below 5 volts and it works again. Marvellous. You are life saver. Thank you very much, sir! ❤
Fixed!! You delivered THE tutorial to fix the most common MTW3 bug :)) I just found a pair of MTW3 and after deepcleaning they looked pretty neat! Turns out right bud is dead. After finding your tutorial I gave it a last try and what should I say? It worked on point! Very happy with a new pair of BT Buds :)) Thank you, Alex!
Much appreciated! send them back tree times under warranty and always gotten replacements. Now the warranty has ran out i can fix them myself. Took a few tries but got there.
Finaly fixed these 🎉😊 Thank you. You can do the same with a 9V as well just be sure to not hold the connection to long at a time. Works well if u hold for 10s at a time for a total of around a minute. 🎉 Love how these sound so really happy Iw got them going again ✨🤙🏼
This was the fix I needed. Thanks! Worked like a charm, though I had to charge it for about 3-5min before I got high enough volts for it to turn back on when put together. 0.7/0.9vDC on my buds though. Were in storage for about 8 months.
Thank you for this! I was doubting that I can do this myself but it WORKED! I’m now having slight trouble in holding the earpiece tightly with the case. Anyways, just wanted to say Thanks!
Perfect. Thanx a lot Alex. My first pair of MTW3s were replaced under warranty because of the dead L earbud. And i was strugguling with the same issue with the newer ones also. 350-400 bucks saved.
Thanks man, really appreciate it, 250 bucks saved, what a shame for sennheiser, but what a sound they deliver. From Latinoamérica, it worked. It was hard to turn it on, but finally, GOT IT!!: No need of multimeter= just if you have the same model as in the video. Just + & - cables, 3 AAA and try!!! I am very happy!
you're a godsend. I really was not looking forward to having to go through the warranty replacement process... again 😂 despite its negatives the internet is great because of folks like you who share their knowledge purely to help others.
Really cool. Did it yesterday as soon as I saw your video, using 5V / GND of a Raspberry for charging. Both earbuds were below 1V so no life sign what so ever, got them up to 3.5 V using your method then put them in case. Now both fully charged and well alive :) Thank you !
Thank you for sharing this. I just tried it on a pair of white TW3s and it worked :-) I did use a small amount of heat from a heat gun to help open the case. The left bud was at 1.2V. RC helicopter controller had 4 AAs so I tapped +ve and -ve from 3 of them to give 4.5V. Waiting for the left bud to complete charge in the case (it's gone from 30% to 40% which sounds promising...). Planning to use a small amount of impact adhesive on case reassembly, but not too much in case I have to do this again!
@@tosejancevski8680 no ,inside is charging controller and it refuse to charge below "safe voltage". You must open it to give a voltage kick directly to the battery and also best option is to replace battery.
Thanks a lot @alex V . Sorry I don't know you name. The steps worked wonders. It fixed my headset. Right one had gone dead and this was a replacement set that Sennheiser had sent me against the flawed momentum 1 that I had bought BIG BIG THANKS! Keep making such helpful videos.
Did your procedure exactly in the same way you explained it in the video and it works great, perfectly !!!! Thank you kindly !!!! 🍺🍾 Would also like tò add a foot note: My left earbud was measured at a pitiful 0.91 volts prior tò beginning the charging process and after the one minute mark was still only 2.8 so i decided tò let It rest for 5 minutes and then give It another one minute. That did the truck ! One minute charge, rest (only because the battery was effectively dead !), then a second one minute charge, put it in the charging case for several hours and now it's breathing again !!!! 💪👏👍
You are a legend. Fixed it with your hack, was worried since I didn't even have the warranty and I had bought them literally 4 months ago. Would advise people not to buy this.
Great stuff! This saved my second pair (which had been already a warranty replacement for the same reason). Unbelievable what the engineers did... Just forget to put them in the charger for some time and they die!!! Shame on Sennheiser for that, which is particularly sad because they sound really great.
Alex thank you very much. I sent it to warranty when it happened first time and it took 2 months to send a new pair of them. But it happened after 4 -5 months later again. So I tried your solution and BANG it worked!. Only issue is it repeats once a week and have to do it again :(
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.
Just fixed following the exact method. I purposely bought one multimeter from Mr DIY yesterday to fix the problem. When I refer back to your video, only I realised it is exactly the same which makes it much easier as I am not really an electrical person. My left earbud was about 0.8 V and I charged using A23 12V battery.
@evanqashanna3447 no you can't charge it while close. You need to open it and it is very safe to use 9 volt I did it that way 9 volt red and black wire from it and did like the video said same poles. You need to reach charing of 3.5 or 3.6 of voltage then put it inside the case and it will work. Mine was dead for 1 year and suddenly saw they video and I did it and wow it working. Spend 3 mins 4 mins till the battery reach 3.5 volt at least.
@evanqashanna3447 hair dryer but put it to high hot air use it for 3 mins then carefully try to open it. After you finish fixing it put silicone the same place the glue was to seal it thanks.
THANK YOU !!!!!!!!!!!!!!!!!!! 100% fixed !!! Left side stopped working after just three months of use!! I was going to throw it in the trash because Sennheiser's technical support in Brazil is terrible!! I bought the left side on EBAY for $80 (include postal service ) but when it gets here, I'll have to pay another US$80 ( Brazilian extortion tax...!!! ) US$160 for left side only. I should have tried your repair before buying the left side!! It will be kept in backup 🙂
Hallo @OctavioPessoa2009, I'm also from Brazil and I'm facing the same issue as you faced. Are you from São Paulo Capital? If yes, have you tried to use the Technical Support from here? I'm having the same issue for the second time and I really want to test this solution from Alex V. I'm just not so sure if the warranty is already expired, I need to check with them, but seems to be impossible, due to the fact that they don't even hang up the phone and the e-mail seems to be wrong :( Did you use 3 Batteries AAA in parallel as in the video? Was it easy to do? Thanks in advance :D
Hello ! I'm from Rio , and yes, its IMPOSSIBLE to contact technical support, they don't respond email and phone I give up! If you bought your tws outside Brazil ( my case) there is only a 3 month warranty. If you bought here, (with Sennheiser Brasil) It has a two-year warranty...... but its impossible contact Brazilian tech sup! I use 4 AAA and its very easy !!! Just follow the video 🙂 @@AndrewAoyague
Hello :-) I live in Rio. It's impossible to contact Sennheiser support Brazil, no one answers the phone or responds to email., If you purchased from Sennheiser Brazil, you have a 2-year warranty, otherwise, only 3 months. About video repair, its super easy !! i use 4 AAA batteries in parallel just follow the video 🙂@@AndrewAoyague
@@OctavioPessoa2009 really nice to know it. Did you take around 5V, or less than that? Or even high? I'm a little bit afraid to use the wrong value for the power supply tension and then loose my phone, even thought it's not working at the moment :( Was it easy to open it?
@@AndrewAoyague Charge between 4.5 and 5v,. To open, you won't be able to do so without first heating the edges. use a hairdryer for about 3 minutes to soften the glue and for close , you won't need glue :-)
Mine got fixed today by using this tutorial. Just make sure the volt of the earbuds must be atleast 3.4+ so it can continue to work in the charging case. If its only 3.3 below it will just show red light one flash. No blue and green. So glad this tutorial existed
This tutorial is really the way to fix this common issue. It’s awesome, simple, but pretty unknown. Hopefully some more people will try and be fine with it :)
A thousand thanks from THAILAND. Since October’22, It’s my 4th pair. The first 2 pair were returned because of sharp noise from the R side. The 3rd one because of R side didn’t wake up anymore after 3 months. This is the last one as it has been out of warranty period and it got problem same as the third one. So lucky that I found your tutorial. Now the problem is solved. Still wonder that anyone experienced this problem repeatedly ?
It seems the warranty still not completely solve the problem. That's why the Sennheiser Momentum True Wireless 4 there is a part saying the battery is from other suppliers, in-app that prevent the battery overly charge~ That makes the owner of Sennheiser Momentum True Wireless 3 feels cheated. #iwantmymoneyback 😂
@@alexv3311. I’ve seen several reviews of MTW4. It really looks similar to our MTW3. The difference seems to be only color of the ear buds and color of logo on the charging case. They make me think about it’s just the remanufacture of returned MTW3 with new battery to take our money again. 😢😢
It works , thanx, left was all dead and ad 10% but made no connection , no lights , but now it turns on again and make connection and play sounds , for now it only charge to 80% but I let it on the power for a while to see if it goes up till 100
Fixed my issue. Took a few goes to yo get Battery volt up( no meter) keep trying!!! Still not impressed with how often a premium product having such a common problem.
man, you made my day. I tried it with my Momentum TW 3 and it is working like a charm. I didn't have a setup to connect 3*1.5V batteries serial way. I used my power bank to do it which I was sure about it produces 5V and 4A. After applying the fix, I also want to say something for Sennheiser. It is totally a bullshit! I've heard few things more ridiculous! So far, I was calling myself as an engineer. it is my profession. but I'm not anymore from today on if the system designer of that product have been hired with a fuck'n engineer title!
Thank you It worked!!!!!!!! Both ear buds is working again !!! But its not sealed its loose what did you use to stick it again sir? @sennheiser pls fix this issue your product is expensive yet your product is like china made but with good audio quality. Poor QC ypu should fix this. This is the first and last sennheiser product that i will buy.
This worked for me. I used a 9v and juiced my earbud for a minute which got me just over 3v on the earbud. That was enough to get it to charge in the case. I got the earbud housing open just by gently prying with my thumbnail. Awesome video. Thank you.
I just tried this but fell at the first fence: I just could not get the earbuds open at all after heating with a hair drier! The hair drier even overheated and gave up. What kind of temperature and how long does the earbud need heating?
Great video, thank you! I had the same issues and fixed the problem exactly as instructed. However, I think I might have put too much "heat" when dissembling, because now the upper part of the casing is going out very easy. Any suggestions how to fix it - should I use instant glue or is there another way?!
Thank you so much for this tutorial. My earbud is now charging again. I just have the problem now, that the casing opens too easily at the seam now. Any type of glue you can recommend to reseal it? Quick tip for anyone attempting this themselves: If you don't have a "fancy" battery case like in the video or another 4.5V - 5V power source, you can just put the batteries in series (positive pole on negative) and tape them together. This should additively up the voltage.
@@mattolika I used the wires of my multimeter. Although one end of these cables had recessed contacts. I just used some aluminum foil to get in there and connect up these to the battery poles. I used the pointy contacts for probing on the headphones.
Welp, just used this video and a hacked up USB cable for a stable 5v supply and jump started an earbud successfully (if a little too melty for getting too close to that heat gun). So thanks!
I didn’t expect to have to do this to a pair of earbuds costing nearly £300 after only 13 months, but it worked a treat, thank you. What glue would you recommend for holding the case together afterwards?
Hi. Thanks for sharing. Will this remove the water resistance in the earbud? I think yes because the glue was removed. Do you think we can glue again to keep the water resistance for the earbud?
I picked up a problem with my set today. The light case shows "green" meaning they are fully charged but when I want to use them my smart control app shows they are only on 20% battery life any Idea what I can do ? Edit: they are only being in use for two months now
Hey man! How much heat did it take you to open them up? and what did you use to make that? planning on trying this fix hopefully to wake them up.Thanks for the fix man truly a life saver!
Great video man :D Could you please do a video about replacing the battery when they finally died or stop working ? Which battery should one get that suits the MTW 3 ?
Yep excellent - left earbud stopped charging and this video fixed it. What a terrible design flaw, the internal battery goes below 1V and the charging circuit stops working. Sennheiser should be ashamed.
It's to protect you from exploding LiPo batteries. LiPos that have been discharged below 3 Volts should be discarded and replaced.
@@artursk2899So..... If you are correct, and I doubt that very much, you forget to charge them for a few months and they become bin fodder. If this is the case, there should be a warning in the paperwork or a notification in the software. They are much too expensive for this fault to be deliberate.

@@martinlouis4492 awesome, thanks for letting me know. I'll post my results when I get time to do this. 🙏
This tutorial is really the way to fix this common issue. It’s awesome, simple, but pretty unknown. Hopefully some more people will try and be fine with it :)
Man, this was a life saver! Thank U!
Welcome 👍
A thousand thanks from THAILAND. Since October’22, It’s my 4th pair. The first 2 pair were returned because of sharp noise from the R side. The 3rd one because of R side didn’t wake up anymore after 3 months. This is the last one as it has been out of warranty period and it got problem same as the third one. So lucky that I found your tutorial. Now the problem is solved. Still wonder that anyone experienced this problem repeatedly ?
It seems the warranty still not completely solve the problem. That's why the Sennheiser Momentum True Wireless 4 there is a part saying the battery is from other suppliers, in-app that prevent the battery overly charge~ That makes the owner of Sennheiser Momentum True Wireless 3 feels cheated.

@@alexv3311. I’ve seen several reviews of MTW4. It really looks similar to our MTW3. The difference seems to be only color of the ear buds and color of logo on the charging case. They make me think about it’s just the remanufacture of returned MTW3 with new battery to take our money again. 😢😢
God bless you man! Thank you very much for sharing this solutionn
Thank you so much !!! Now my earbud are working again,, it really works:D
Awesome 👍
Appreciate the tutorial worked for me 🙏🏽
Awesome 👍 Good to be back 🎧
Great fix! Worked a treat! Thank you!
And Sennheiser, get your act together.
Or is this even part of the design? Hmmm…
Awesome ! That worked ! Great video bud !
Aww man.I threw mine away thank you for figuring this out!
I'm about to do the same 😬
@@alexv3311why? you fixed them, right?
@@alexv3311did it stop working again?

Thanks a lots. It work and save my both earbuds.
Awesome 👍

beeindruckend 👍
Worked Perfectly Thanks!!!

Awesome 👍👍
Thank you for sharing this, it worked for me.
Awesome 👍
Great job bro. But i’d rather return mine (both not working) and claim warranty. Thanks!
Are you based in the US? How long does it take for them to fix it and ship it back?
Thank you!
Ohh man.. it worked. Thank you so much
awesome 👍
Fixed my issue. Took a few goes to yo get Battery volt up( no meter) keep trying!!!
Still not impressed with how often a premium product having such a common problem.
man, you made my day. I tried it with my Momentum TW 3 and it is working like a charm. I didn't have a setup to connect 3*1.5V batteries serial way. I used my power bank to do it which I was sure about it produces 5V and 4A.
After applying the fix, I also want to say something for Sennheiser. It is totally a bullshit! I've heard few things more ridiculous! So far, I was calling myself as an engineer. it is my profession. but I'm not anymore from today on if the system designer of that product have been hired with a fuck'n engineer title!
Great video!! It saved me!!
Thanks a lot. It's working now :)
Good job 👏
It's apply if the earbud that doesn't charge it gets hot at the moment that it get in the case?
Does anybody know which hole is positive/negative? I want to try without taking it apart first.
Thanks man ! this is it !
Thank you It worked!!!!!!!! Both ear buds is working again !!! But its not sealed its loose what did you use to stick it again sir?
@sennheiser pls fix this issue your product is expensive yet your product is like china made but with good audio quality. Poor QC ypu should fix this. This is the first and last sennheiser product that i will buy.
This worked for me. I used a 9v and juiced my earbud for a minute which got me just over 3v on the earbud. That was enough to get it to charge in the case. I got the earbud housing open just by gently prying with my thumbnail. Awesome video. Thank you.
Sorry but what tools do you use to charge it up/?
I just tried this but fell at the first fence: I just could not get the earbuds open at all after heating with a hair drier! The hair drier even overheated and gave up. What kind of temperature and how long does the earbud need heating?
Great video, thank you! I had the same issues and fixed the problem exactly as instructed. However, I think I might have put too much "heat" when dissembling, because now the upper part of the casing is going out very easy. Any suggestions how to fix it - should I use instant glue or is there another way?!
Thank Alex, It can fixed without remove the cover?
Thank you so much, it’s really works,
Anytime👍
Thank you so much for this tutorial. My earbud is now charging again. I just have the problem now, that the casing opens too easily at the seam now. Any type of glue you can recommend to reseal it?
Quick tip for anyone attempting this themselves: If you don't have a "fancy" battery case like in the video or another 4.5V - 5V power source, you can just put the batteries in series (positive pole on negative) and tape them together. This should additively up the voltage.
What wires did u use to touch the poles to the earphones? 🙏
@@mattolika I used the wires of my multimeter. Although one end of these cables had recessed contacts. I just used some aluminum foil to get in there and connect up these to the battery poles. I used the pointy contacts for probing on the headphones.
can do this through the charging connectors on the earbud instead of taking it apart? If so, which is positive and which is negative?
Welp, just used this video and a hacked up USB cable for a stable 5v supply and jump started an earbud successfully (if a little too melty for getting too close to that heat gun). So thanks!
you are a hero
Thank You!
I didn’t expect to have to do this to a pair of earbuds costing nearly £300 after only 13 months, but it worked a treat, thank you. What glue would you recommend for holding the case together afterwards?
I have donr the same thing to wake the right earbud. However, after waking it up it got some weird noise now. Do you have any idea about that?
Love all the helpful words to help us all!💩🥴🤔
Do you have to open the earbud? Can you not connect the 4.5V to the terminals?
Thanks!
You’re a lifesaver
I was able to ressurrect the right bud, but the left one will not work. Is battery replacement an option?
Hi. Thanks for sharing. Will this remove the water resistance in the earbud? I think yes because the glue was removed. Do you think we can glue again to keep the water resistance for the earbud?
I picked up a problem with my set today.
The light case shows "green" meaning they are fully charged but when I want to use them my smart control app shows they are only on 20% battery life any Idea what I can do ?
Edit: they are only being in use for two months now
I sent mine back to the manufacturer. Hopefully they fixed them.
Hey man! How much heat did it take you to open them up? and what did you use to make that? planning on trying this fix hopefully to wake them up.Thanks for the fix man truly a life saver!
Heat gun or ordinary hair dryer also work. Put some heat until you feel it's easy to open.
Damn i did not expect them to ever work again but they are fixed!! Thanks a lot man,and also did your pair of momentum 3 ever got any problem after?
Thanks to you, I was able to re-animate my TW3 and also even older TW2! Amazing guide! Thanks!
does the Problem recur after the procedur? I have this Problem with my 3rd Momentum 3, every time with the right earbud...
Great video man :D
Could you please do a video about replacing the battery when they finally died or stop working ?
Which battery should one get that suits the MTW 3 ?
Sure.. I don't have the tools to replace the battery yet.
@@alexv3311 okay what kind of tools/ toolkit would you recommend ? maybe i need to order the same...
Спасибо тебе, друг! Ты крут!
great video thanks for that! wish these awesome headphones wernt so dumb!
Can you apply voltage to the external contacts?
