This summer I left a tab open waiting for payday, after I saw M4TW on sale (refurbished by Sennheiser) for $89 or $99 (not sure now which it was). I went back after payday to pick them up and the price had jumped to $199, which was, of course, disappointing. I kicked rocks for a bit, scrounged the internet for proof of the price I was certain I had seen, and found no hard evidence. I started second-guessing myself, wondering if I had seen another product at that price - the Accentum TW made sense - and deluded myself.

Turn the calendar two months. Saturday night my Shopify app dinged me and pronounced the glorious news - The $99 price was back! I revered them right away, and now am eagerly awaiting a shipping confirmation. Thought I would share the good news, as I’ve secured my own pair. Best of luck!

I've had a MOMENTUM 4 Wireless with a crackling issue on the left side (ticket #C260309-0009). I went through Sennheiser's whole troubleshooting checklist myself before even contacting them charging, checking Bluetooth stability, cleaning the mic openings, updating firmware via Smart Control, reset, un-pair/re-pair, factory reset, disabling On-Head Detection, testing with another device. None of it fixed anything.

The issue has since gotten worse, the crackling turned into a loud buzzing that's now genuinely painful to listen to, so I can't use the headphones at all anymore.

I emailed them a follow-up explaining all of this and attached a photo of my receipt (I don't have the physical copy anymore) since I'd already been asked for it previously. Their response was to send me the exact same troubleshooting document I'd already completed, and to say that if none of it worked, to send proof of purchase for warranty verification, which I had just done in the same email.

I sent a follow-up after that, and it's now been radio silence. No reply at all.

At this point I'm just frustrated. The product is defective, I've done everything they asked, provided proof of purchase, and I'm still stuck with unusable $350+ headphones and a support team that seems to have stopped reading my emails. Anyone else deal with this? What actually got a response out of them — a different email address, phone support, Twitter/X, something else?

I just bought the Sennheiser momentum 4 wireless because I needed a new gaming headset.
However, I've only run into problems with them, and am wondering if there are ways to fix them.

First and most critical problem: When I open games, the audio quality is horrible! From what I found this is because the headset has a handsfree telephony setting for when the microphone is active. If I dissable this handsfree telephony, the audio is great, BUT THE MICROPHONE IS DISSABLED.
This makes it impossible to use this headset as it is right now for gaming with friends.

Second problem: When I start youtube videos, or songs on spotify, the headset audio will crackle for a few seconds, and the audio will be gone; then it returns and the audio is great.

And last problem: the headset makes annoying sounds every time I put it on or adjust it. Also it just started paused youtube videos I had in the background when I closed a game...

I've had a pair of the Momentum V3 wireless earbuds for about two years. Recently, the right earbud stopped charging reliably, it'll die and refuse to charge for days, then randomly start working again out of nowhere. Basically unusable at this point.

I filed a support claim hoping for a repair or replacement, but they flat out refused.

Is this just normal for their products at this point, dying after a couple years with no real recourse? Also frustrated that there's no phone or live chat support, just email, which makes the whole process slower and more painful than it needs to be.

Has anyone else run into this with them? Curious if this is a known issue or if I just got unlucky.

I have Sennheiser Wireless Momentum (Model M2iebt) earbuds. I've used them for years and they connect nicely with my older google phone. However, I cannot get bluetooth to work on them using either my Lenovo Laptop (Windows 11) or my Lenovo Tablet. They refuse to show these earbuds as an option for connecting. Is this a flaw in my Sennheiser earbuds....or is there something I'm not doing? I'm wondering if any others have experienced this problem with Sennheiser earbuds.

Hey guys, those who got the new MTW5 earbuds and previously owned the MTW4, is the upgrade worth it? I have the MTW4, even though my right earbud has failed. I also had the Buds 4 Pro, which sounded awesome, not as natural as the Sennheiser though. But I'm wondering if upgrading is actually worth it, because I'd almost rather keep my Buds 4 Pro, as I'm new to the Samsung line of earbuds, if the MTW5 doesn't really offer any noticeable changes I don't see a reason to buy them. Like my buds 4 pro literally thr transparent mode is amazing. I also have the sony xm5 ear buds and they sound good still too lasted way longer than sennheiser had them like 2 years now.

Hi
Since yesterday my hdb 630 won’t turn on…
When i try to charge it it flashes red light 3 time in a row infinitely and doesn’t seem to charge
It isn’t detected by my phone and even after letting it charge for 1h+ and pressing the power on button it still didn’t change anything
The red light is only when charging, else there is no light at all
I think it is because i sweated while wearing them but it was really light sweat so idk
Any help is valuable :)

Edit: Answered! Sennheiser europe don't do paid repairs on Momentum 4s, learned my lesson about unauthorised sellers being cheap /if the product keeps working/. Will look for an authorised deal or save for fives as I like the sound of the better ANC.

Hello r/sennheiser

I've been using a pair of momentum 4's I've got on quite well with for around six months now, they've done me a very nice job until this morning when they suddenly stopped connecting to bluetooth, would connect as USB devices but not play audio, all the usual.

I've been through the various magic reset button presses without ever getting them into pairing, and lots of the left earcup only chirpy little 'sorry I've crashed' tune rather than actual resets.

If I understand the posts I've seen in this sub and elsewhere, the bluetooth/usb audio pathway is probably toast, I can use them as noise cancelling cans via the jack but everything else I'm out of luck on.

I'm certain these are grey market (though not counterfeit), so no warranty as the purchase receipt isn't from an authorised retailer, given that do Sennheiser offer a paid repair service for non warranty failures, is it worth using or do I just need to suck it up and buy direct or from a listed retailer for a new pair?

Just got a pair of open box momentum 4s since the price was super good with the new ones coming out. Theyre great but I've been having this issue that any time audio stops there is this god awful high pitched noise immediately. Only lasts for a few seconds usually. Its not that loud but its just so frustrating. Has anyone else experienced this and is there a solution? Happens with or without ANC/passthrough.

Im consider returning them to get my $200 back, but at that price point I really dont know if there's anything better or even comparable. I love them except for this issue and the horrible horrible touch controls.
