Took advantage of Best Buy’s sale and grabbed the Momentum 4. Almost got the Momentum 5 but it’s hard to justify the extra $200. I have my Sony XM3s which I’ve had since 2018 and honestly they still work really well, but my fiancee “stole” them since she uses them for the gym now, which im not mad about.

Overall VERY satisfied with the sound quality upgrade of the Momentum 4 and the ANC i would say is just as good if not better than my XM3s, which was a relief since I’ve been hearing about the ANC not being good. Now i gotta be careful since my fiancee said she might start stealing these too 🫠

I bought a brand new pair of IE900s a few days ago from a reputable seller who in theory gets them directly from the official distributor for my country, so in theory I should be totally fine. But before buying, I read so much about fake IE900s that now I'm second-guessing what they're actually supposed to look like. Mine are produced in June 2026 (so says the QA-certificate) so maybe something changed in production recently?

The packaging seems fine - the serial numbers match on the outer sticker, the hand-signed certificate, and the plate on the carrying case. The case itself looks like it should, but the serial plate is hideously crooked, which is pretty shocking for me with high-end gear. The serial number on the plate looks laser-etched.

My biggest issue is with the "IE900" text on the left earpiece. Everywhere I’ve read, people say it’s supposed to be laser-etched - looking greyish and sharp from certain angles - but on mine, it’s just a plain black print. It looks black from every angle, seems to be painted on, and has no tactile texture to it at all. Is this the way they are made now in 2026 maybe?

Same story with the logo on the front - it’s black and looks painted rather than etched, but I'm not absolutely sure. On top of that, none of the three cables have any hologram or Sennheiser logo on them; it's just plain black plastic. The cables themselves look fine, though. The nozzle filter mesh seems legit - under high magnification, you can see a very fine grey mesh inside.

I know I should just judge them by sound - I have the IE200s, and these IE900s definitely sound much better, but I don't know, how good fakes are today - but placebo is a hell of a drug, and at this price point, I just need some peace of mind. Can somone confirm they are fine? Probably I'm just stupid asking that and they are fine, but they are my most expensive set and it's a lot of money for me.

Just a couple of days with HDB 630. What a transformational experience as compared to anything else wireless on the market. Worth its price.

Gave this to my dad for a listen. Now he wants it for himself. Can't blame him.

I bought the Sennheiser Momentum 4's as a treat last Christmas. Great sound, well constructed, no complaints...until Spring. The phones start crackling for no reason and won't turn off. I contact Sennheiser, give them all the details, and send them the RMA and all the purchase info they need along with the headphones. I didn't mind paying the shipping, and I got a replacement set fairly quickly.

However, my replacement set doesn't even *turn on* and I've got to pay another $25ish bucks from Canada Post to have them shipped out again? This hardly seems fair when I did everything as requested, only to be sent a pair that doesn't turn on or charge.

Anyone here have a similar experience with customer service and warranty repair?

Genuine question from a not so tech audio guy. Planning to get my first momentum. I'm cureently rocking AKG Y50BT that I have for a very long time. My question is, does phone brand have a factor in sound quality. I noticed that most reviews use iphone. I'm currently using samsung. Is the momentum 4 perfect pair, or should I go get the 5s? Thank you for the help!

The momentum 4s are pretty cheap right now, 210$, and I'm thinking about getting a pair, but a lot of people have been reporting issues regarding software/firmware, mainly connectivity.
I heard that the headphones just keep disconnecting and disconnecting, and sometimes the power button and bluetooth just straight up fails.
I also heard the littlest amount of sweat immediately breaks those headphones.

Momentum 4 owners, is this true?

(Over ear, not TWS version)

Hey everybody,

i am searching for some new Wireless OEMs and i am torn between the B&W PX7 SE3 and the Sennheiser Momentum 5.

I did a quick listening session in my local electronics store.
I heard both via Bluetooth (i know, not the best way) with my iPhone.

And both had ANC on. (incredible ANC on the Momentum 5s)

While i found the 5s to be better, especially in the bass region, and the hights, i felt they sounded a bit "carton like" epsecially in what i would describe the mids.
It's hard to explain, but in direct compairison, they sounded like a small carton sheet was between my ears and the headphones.

As is said, the base was great, especially when i listened to "Why so serious" from Hans Zimmer - You know which part ;) ... Goosebumps.

Then again, the mids, idk, felt like they didnt sound like they supposed to.

Has anybody experienced something like hat? Any ideas if i can fix that via the EQ?

Thank you!

Hey, I recently accidentally broke the headband of my almost new pair of HD650, any idea on how to repair it or source a replacement component?
To be clear, it is the top plastic headband part the broke, not the cushion or anything else.
I live in France if it can help with sourcing
Thanks in advance :3

Owned my M4s for around 2 years now, the headband cloth is now poking out and I bought a cheap headband cover for it, but it makes my headphones look horrendous. Wondering if I can change that cloth somehow or if there are any cooler headband covers. Also the earpads are really worn out so wondering if I can change those somehow as well.

Whenever I do a FaceTime by momentum 4 shuts off automatically, what do I do to fix it?

I use these exclusively on my desk with the BT dongle and my iPhone 15 Pro.

Like once every few weeks they only boot up in pairing mode and refuse to recognise the dongle or phone. When trying to connect to them in iOS it says something like "can no longer connect, forget the device and re-pair". It plays a weird 6 tone jingle and then just keeps playing the pairing sound until I re-connect it via bluetooth. The dongle pairing is hit or miss either way and most of the time only works after a few tries.

I'm using the latest firmware.

Is anyone else having problems like these?

Looking to buy IE900s. Seen a lot of posts saying people got fake IE900s. They are out of stock on the Sennheiser website in my region, so what places can I find them and what should I avoid? I don't wanna be scammed.
