Anyone notice that left earbud is only 60mAh battery while the right side is 85mAh?
They’re really comfortable and just sound amazing.
On Saturday I wasn't going anywhere and left them in the case with the case plugged into my computer (using an AmazonBasics USB-C cable on both ends). The buds sound great but the battery tech is maddening. With the Momentum True Wireless, Sennheiser delivers on sound—but it isn’t immune to some of the more annoying problems facing all fancy-free buds. Sennheiser are saying late March for the firmware update which promises a fix. IMO the way the battery works on this system is incredibly bad design, and it bothers me to no end that this information is available absolutely nowhere in Sennheiser's marketing or specs materials, and it wasn't in a single review of the system at launch. I'm on my 3rd pair since January.
This way, they will power on and connect quickly when removed from the case. .
Someone on here said a while back, different chargers impart different power through the cable so it might be that the Sennheiser charging case can only accept wall charger output using a phone plug or other USB-A adapter. I don't use the bluetooth wireless function so far (I know it's kinda ironic buying a wireless headphone to use wired). just updated today and eveything has been fixed!
I bought a Sennheiser momentum wireless 3 (the over-ear headphone) and I am really loving it - the sound and build quality specifically. Left mine sitting for a few days.
Momentum True Wireless - is the battery issue a deal breaker?
Guess that’s why they keep going down in price.
Here's the official response from Sennheiser when I reached out them about this back in December: When the Momentum True Wireless earbuds are placed into the case, they go into a low power stand by state, and the case provides a trickle charge to keep the battery topped off. Moving on, Sennheiser also says that the Momentum True Wireless 2 earbuds also feature come with improved battery life.

4 months later and this still hasn't been fixed. I returned my MTWs for a number of reasons, including this one - but I wanted to share that this issue affects other products.
When it was pulsing orange I took out the earbuds and the case went to solid green. New comments cannot be posted and votes cannot be cast, Press J to jump to the feed.

I'm very close to buying the same ,but heard about this issue everywhere I looked .Wanted to know if the battery drain issue ,when earbuds are kept in the case is resolved or not ? idk but they did include a cable so maybe that's a clue.
Which explains why left drains faster than the right side.
Not sure whether to purchase these given the reports of a battery drain and users commenting that this makes them not fit for purpose.
In summary, I now only use a wall charger with USB-C directly into the charging case and have had no problems since. If they aren’t fixed I may save up for the IE 80 S wireless. firmware 1.25.0 go ahead and update now! That said, the earbuds themselves remain in standby at all times, rather than powering off—meaning they're discharging slowly at all times.
Yea, that makes sense at least what's happening not the why.
If the battery is out of the case, the headphones do not know that they should go into "standby" and the battery in the headphones may run out faster. I don’t know what firmware you guys are using but they released a version where you can shut down the earbuds from the app... so yes they did address it. Hi guys!
I won’t be picking these up then. Press question mark to learn the rest of the keyboard shortcuts. I think these sound better than my wired IE 80’s. Pulsing yellow actually means "... earbuds are being charged via the rechargeable battery of the charging case", whereas it's the solid yellow that means the case is below 50%. It charged and was a solid green. I have charged my buds for hours using the charger for my MacBook Pro only to see the case go orange after barely using the buds.

Meanwhile, earlier this month they told me the firmware update would be by the end of February. When fully charged, the right earbud provides a four-hour battery time, ensuring that the full MOMENTUM True Wireless system offers the specified four hours of play time.
