The Momentum True Wireless has been a massive disappointment
First off, I pre-ordered the MTWs immediately after hearing about them and did the whole "obsessively checking tracking info" thing once they'd shipped. Transparent Hearing meant I could finally wear headphones at work and still be able to hear the phone ringing, or when someone knocked on my door. I'd be able to listen to music while walking my dog, getting exceptional audio quality and no longer having to get tangled in headphone wires or deal with the bumping sound of the wire while walking.
Needless to say I was very much looking forward to these things, and I take no joy in my disappointment.
I'm going to skip the positives, because there are plenty of comprehensive reviews of these things out there touting how great they sounds, how comfortable they are (well, at least once you upgrade to Comply tips), etc. What these reviews miss, however, is how these hold up over time — particularly for people like myself, who don't and never intended to use them every single day.
Anyway, over the past month I've used the MTW's for maybe a total of 3 hours. Upon receiving them I charged the system fully, as directed by the... directions. According to Sennheiser's marketing material the MTW buds should hold 4 hours of charge, while the case holds an additional 8. Well, on 4 occasions now I found that the charging case was drained completely, which causes the earbuds to power on. According to Sennheiser, the earbuds require power from the case to 1) power off and 2) remain powered off, so when the case is depleted the earbuds will automatically power on and... drain some more. Because there is not yet a way to power off the buds manually, at this point the only way to turn off the earbuds is to put them in the charging case and connect the charging case to a power source. If you can't access a power source when this happens, you're simply out of luck.
Recap: I've used the earbuds for 3 hours, but the charging case has depleted at least 32 hours worth of charge (8 hours on 4 occasions).
Adding to this problem is the fact that the charging case seems to be depleting at almost all times. If you're in a quiet room and you hold the charging case up to your ear, focusing on the black "lip" part, you'll likely hear the faint but recognizable digital buzzing of battery discharge. This happens regardless of whether or not the case is actually charging the buds, and explains why my charging case has depleted 3 times for no apparent reason. And this is not unique. A quick search of r/sennheiser will yield plenty of results of others who have experienced the same thing, and I've yet to find an instance where an RMA has actually solved the problem.
I emailed Sennheiser about this on January 2 but have yet to receive a response.
Anyway, the purpose of this post isn't to shit on Sennheiser or the MTWs, but to highlight the problem. I haven't seen a single official review out there that makes mention of any of this, so it needs to be said somewhere, and potential buyers deserve to know that all battery life claims of the MTW should be taken with a massive grain of something salty.
EDIT: If you're experiencing this same issue, please reach out to Sennheiser about it — whether it's a phone call, email, Facebook, or Twitter. To be clear, I'm not at all suggesting this in the "everyone grab your pitchfork" way, but rather to make sure they're aware of this issue in the hopes that they'll address it.
EDIT 2: Here's the official response from Sennheiser, received 12 days after my initial email:
"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. This way, they will power on and connect quickly when removed from the case. Starting with a fully charged case and headphone, it should take 7 days of standby time for the case and earbuds to completely drain."
My thoughts on this response:
- This is a poor design decision.
- This should have been mentioned somewhere in Sennheiser's marketing material, because it boils down to being an asterisk next to all claims of battery life. And I, for one, never would have purchased the MTW in the first place if I'd known this.
- At the very least it should include an option to have the earbuds power off completely when inserted in the charging case, for those of us who would gladly sacrifice initial connection speed for battery life.
EDIT 3: Sennheiser released a firmware update on March 6, but go figure it has absolutely nothing to do with the battery drain flaw.

I'm facing the same issue, and it's been really frustrating. I charged my pair/case fully yesterday, used the buds for about 30 minutes, this morning my case is showing under 50% battery. This is unacceptable for a $300 pair of earbuds. At this point I'm contemplating returning them, which sucks because I was so excited about them. :(
50% idle drain over the course of a single day? That's nuts!
And yeah, I'm pretty sure I'll be returning mine as well. I'm going to give Sennheiser a bit more time to respond and see if they can clarify anything, but for me, having to worry so much about the battery is a dealbreaker. I don't want to be charging these things every single day if I'm not using them, not only because that's tedious but because that kind of constant drain/charge will eventually tank the capacity/health of the battery to the point where the problem consistently gets worse over time.
Yup, and that sucks because there isn't another pair or TW buds in the market that entices me. Gonna have to keep an eye out during CES.
B&O E8? My set sits in my bag for weeks at a time and are at or close to 100% whenever I pull it out.
How do the E8s sound? I’ve never tried anything from B&O. Are they water resistant (I live in Seattle so could I wear them in a light rain)?
I was dead set on the Sennheisers, but now I’m not so sure.
I’ve been waiting for the Jabra Elite actives to go on sale. I can wait though.
How are you seeing the case battery level?
By clicking on the button at the back.
If the light flashes:
Green - More than 50% left
Orange - Less than 50% left
Red - Empty
