First of all, sir you are awesome! your solution totally works, thank you very much for sharing this!!!! For all who is interested, you need a bench supply, set it up V=3.6v I=1.00A. what this clever guy is doing is injecting this voltage to the battery for like 5 to 7 sec, (you must see in your supply the draw of current) after that put it on the case , it may not react at first , if that's the case just repeat the procedure
I'd limit the current to a lot less, like 50mA or 100mA or so. Issue is that if the cell is broken rather than discharged, pushing 1A through it probably will make it heat up and potentially leak or explode. I kept the leads on until my cells were charged to 3.0V, at that time they're happy to charge by themselves again.
Cant you tell? Take it out of the case, tap it a few times, put it back in the case, tap it a few times. Rinse an repeat. Problem solved. Honest answer though; from what I can work out, the speaker was faulty and was likely replaced but that part of the video isnt shown.
Hello all this hack also works for Momentum 3 tws, tried with five pairs, all repaired. What you need is to apply same steps as shown in video. I used three AAA batteries to get 5V and directly applied it to ear bud for 30 seconds (then checked the voltage if it is more than 4v should be good), then put it in the case. Wait for some time 5 - 10 minutes. If ear bud stared to show some signs leave it in charging mode for longer if not redo upper steps.
Can you please send a link to purchase Momentum True Wireless 2 batteries , Another question, do both headphones have the same battery and what is their model please? I'm talking about a headphone model Momentum true wirelles 2 !!! thanks
The batteries are Varta CP1254 and sold by many distributors. Just make sure to choose a valid one and avoid buying from shady ebay sources or from Chinese vendors - these are made in Germany, so there is little reason for them to be cheaper there.
@@lolo2lolo491 I would first just try it with a normal hairdryer with a nozzle, it might just be enough to dissolve the glue and make it possible to pry them open...
@@finnibat yeah i think that be good.. but i still want to wait until you make the video of the entire replacement so i dont mess my MTW3 cause they dont have much battery life left and the charge barely hold 2h listening time :(
If you skip the background sounds, turn off the BGM or just put a relaxing ambient/instrumental/elevator music instead of. This could be one of the most relaxing involuntary ASMR video that i ever seen before. CONGRATS!!
Hello ! Please can you tell me if it's normal for momentum 3 tws charging case to charge from 50 procent to 100 in just 15 minutes with a slow charger with provided cable ? I think it's too fast.Is it normal? They are new and working fine otherwise. Thank you!

簡單來說，就是耳機放太久電池沒有自主電力，無法抓到充電艙的電，灌入約1.5V電壓，來回測試，電池沒有問題就可以自主抓到電壓了!

T7000
Hi my right ear bud keeps cutting out and then reconnecting again. Any suggestions of what it could be?
Thanks
Can you do a battery replace?
Do you boost the battries with a external PSU set to 3.7V?
Exactly what he did. + on +, - on -. but it doesnt work every time, sometimes battery is dead. U can use 3.7v battery

If you know how to solder, it's fairly easy! The batteries are Varta CP1454 A4.
