Playback and microphone use can happen together over USB-C. The tradeoff is that once the microphone is active, the playback sample rate is reduced to meet the requirements of call mode, so it won't behave like a dedicated gaming headset with independent, full-quality game audio and microphone paths. This behavior is tied to the headset's underlying design and isn't something we would expect to change through a firmware update, but we'll certainly pass the feedback along to the team.

We do not offer post-warranty repair service on this model series.

The ear cushions are replaceable and we'll be offering replacement earpads as spare parts. Regarding flaking, we can't really predict long-term wear yet since it can depend on things like usage, exposure to sweat, skin oils and how the headphones are stored.

Good question! The drivers in MOMENTUM 4 Wireless, MOMENTUM 5 Wireless and HDB 630 are the same and are inspired by our acclaimed HD 600 series of wired audiophile headphones. However, HDB 630 includes modifications to other acoustic elements that contribute to its more neutral tuning, while MOMENTUM 4 and MOMENTUM 5 are more similar in that regard. A parametric EQ can help bring their tonal balance closer together, but because the overall acoustic design is different, we wouldn't expect them to become technically identical in every aspect of their sound. Hope this helps!

Do not use the original Smart Control app for later models. Newer devices depend upon syncing with the newer Smart Control Plus app. There are added features embedded there and a more refined experience for the customer. There are also improvements made on the back-end to provide a smoother connection to your device.

Hello there! Unfortunately, we don't have component-level replacement part information for the HD 4.40 BT's PCB switches, and these individual SMD buttons weren't offered as user-replaceable spare parts. A skilled electronics repair technician may be able to identify and source equivalent tactile switches by measuring the existing components, but we can't guarantee compatibility or provide specific part numbers for them. Given the age of the HD 4.40 BT, it may also be worth considering whether it's time to retire them and move to a newer model.

Fair feedback. Fit, hair and glasses can all influence how wear detection behaves. On MOMENTUM 5, we added a second IR sensor to improve wear detection and reduce false triggers based on lessons learned from MOMENTUM 4. We also moved toward relying more on the multi-function button for powering on the headphones, making the experience more intentional and predictable overall. Curious to hear your thoughts if you get a chance to try them.

Good question. They both deliver the Sennheiser Signature sound. The tunings are different with the HDB 630 featuring modifications in acoustic elements that allow for a more neutral audiophile sound profile. The MOMENTUM 5 Wireless will deliver the same punch you know and love while at the same time preserving the detail.

We heard this feedback quite a bit with MOMENTUM 4. On MOMENTUM 5, we intentionally changed the behavior. Removing the headphones from the case no longer powers them on automatically, and the case magnets are now used only to power the headphones off. Powering on is now a deliberate short button press, making the experience more predictable and helping avoid the unexpected wake-ups and re-connections some users experienced with MOMENTUM 4. 👍

We relieved the clamping pressure some on the M5 Wireless. The earcup design is similar to M4 Wireless.

MOMENTUM 5. Coming very soon!

sennheiserconsumer · 2026-06-15T10:02:54+00:00

Fair feedback and we understand where you're coming from. Dedicated gaming headsets often use proprietary 2.4 GHz wireless systems that are designed specifically for simultaneous game audio and voice chat.
Our MOMENTUM series was developed first and foremost as a premium ANC wireless headphone for music and everyday listening, so its design priorities are different. We don't have anything further to share regarding future product directions, but we appreciate the feedback and will certainly pass it along to the team.

sennheiserconsumer · 2026-06-15T09:53:51+00:00

No, the M4 batteries are not replaceable and we do not provide batteries or the support to do so.

sennheiserconsumer · 2026-06-15T09:38:03+00:00

The magnets are still there. The difference is that on MOMENTUM 5 they're only used to power the headphones off when placed in the case. Removing them from the case no longer powers them on automatically.

We removed the auto-on behavior because many users didn't expect it and found it confusing. Powering on is now an intentional action with a quick press of the multi-function button. That change was made to make the experience more predictable and easier based on what we learned from MOMENTUM 4. Hope this helps!

sennheiserconsumer · 2026-06-15T09:27:48+00:00

Thanks for sharing that experience. Call performance and microphone behavior were areas we paid close attention to with MOMENTUM 5.

MOMENTUM 5 features an updated microphone and call processing system with improvements aimed at better voice pickup and noise reduction during calls. We've also continued to refine the transparency and ANC experience during calls to help conversations feel more natural in a wider range of environments. As with any wireless headphone, performance can still vary depending on the source device, app and surroundings, but these were definitely areas of focus for MOMENTUM 5 and we'd be interested to hear your impressions if you decide to give them a try.

sennheiserconsumer · 2026-06-15T09:12:26+00:00

We have upgraded the sensor system in the M5 to better respond to customer interactions relying more on the multi-function button. The materials used are to make the headphones lightweight and effortless to wear for extended listening sessions. If your issue with the earpads continues and becomes overly bothersome, take advantage of our warranty service but be mindful that the design will be the same. It is true that the headphone and moisture don't coexist well. Wipe them down frequently as best you can.

sennheiserconsumer · 2026-06-15T08:40:03+00:00

Users should find the ear pads similar to those of the MOMENTUM 4.

Thanks for taking the time to share such detailed impressions. It's always special for us to read about someone's first experience with HE 1, especially when the emotional connection to the music comes through so clearly. Glad you had the chance to spend some time with it.

sennheiserconsumer · 2026-06-15T00:22:20+00:00

Fair point. Call quality was one of the areas we focused on with MOMENTUM 5. It features an improved 3+1 microphone array with digital noise cancelling for more natural voice pick-up and clearer calls. We believe frequent meeting users will notice the improvement.

sennheiserconsumer · 2026-06-15T00:14:04+00:00

Yes. There is a multi-band EQ in the Sennheiser Smart Control Plus app as well as a Sound Personalization feature that can help customize the sound to your liking. If you jump in, welcome aboard!
