The Sennheiser Momentum 4. Sonova leans on ANC and long battery life

Sennheiser Momentum 4 Wireless sits on the table with its fabric-covered earcups catching the light, the matte headband cold to the touch before you put it on. The Momentum 4 Wireless is Sonova’s quiet workhorse in over-ear ANC headphones, designed for long listening sessions and daily commuting.

Design, comfort and everyday use

When you pick up the Momentum 4 Wireless, the soft ear cushions feel dense yet pliable, clearly built for hours of wear rather than short flights only. Sennheiser describes the design as a more understated look compared with earlier Momentum generations, with less metal and more smooth plastic for lighter weight.

According to Sennheiser’s product team, led on the consumer side by global CMO Gregor Kahr, the goal was a travel-friendly headphone that can be worn all day without the clamp fatigue some rivals still cause. The earcups swivel flat for easy packing, and the included case has compartments for cables and the in-flight adapter.

Battery life and active noise cancelling

The headline spec on the Momentum 4 Wireless is battery life. Sennheiser quotes up to 60 hours of playback with ANC turned on, measured at moderate volume using SBC codec. Independent reviewers from What Hi-Fi and RTINGS broadly confirm this ballpark, reporting real-world endurance close to the advertised figure.

Active noise cancelling is adaptive and uses multiple microphones on each earcup. The system monitors ambient noise and adjusts attenuation, while a transparency mode lets through voices and traffic when needed. A wind-reduction feature tries to keep low-frequency rumble under control on blustery platforms. One tap on the right earcup switches between ANC profiles in the Sennheiser Smart Control app.

Sound profile and codec support

Under the fabric grill sit 42 mm dynamic drivers tuned for a balanced, slightly warm sound signature. Reviews highlight a controlled bass lift without overwhelming the midrange, clear vocals, and a treble that stays smooth rather than piercing. In the Sennheiser app, listeners can apply presets or build custom EQ curves to push the sound towards brighter or more bass-heavy territory.

On the wireless side, the Momentum 4 Wireless supports Bluetooth 5.2 with SBC, AAC, aptX and aptX Adaptive. That gives Android users access to higher-bitrate streaming and lower latency in compatible phones, while iOS devices settle on AAC. Multipoint connectivity lets the headphones stay paired to two devices at once, for example a laptop and smartphone.

Controls, app integration and calls

The outer surface of the right earcup is a capacitive touch panel. Swiping adjusts volume or track skipping, and taps handle calls or ANC toggles. Some reviewers note that the gestures are reliable once learned, but there is a short adaptation phase compared with classic button-based controls.

In the Smart Control app, available for iOS and Android, users can configure sound zones, tweaking ANC and transparency levels based on location. There is also a Sound Check feature that guides the user through A/B comparisons to generate a personalized profile. Firmware updates for the headphones are delivered over the app, and Sonova has used this channel to refine ANC behavior post-launch according to release notes.

Materials, build and travel experience

The headband is padded with a synthetic leather-like material that feels slightly cool when you first put the headphones on. Sennheiser offers the Momentum 4 Wireless in black and white colorways, both with a fabric outer ring on the earcups that catches lint a bit more than pure plastic.

The supplied case is semi-hard and shaped to the folded form of the headphones. Inside, separate pockets hold the USB-C charging cable and analog 3.5 mm cable for wired listening. Travelers report that the case fits easily into standard laptop backpacks without creating bulky corners, a pragmatic detail for commuters.

Position in Sonova’s portfolio and stock context

Sonova acquired the Sennheiser consumer audio business in 2022, adding headphones like the Momentum 4 Wireless alongside its established Phonak and Unitron hearing care brands. CEO Arnd Kaldowski has argued in interviews that this move broadens Sonova’s access to younger listeners and creates cross-technology synergies between hearing aids and lifestyle audio.

Within Sonova’s reporting, the Sennheiser consumer line now sits in the Consumer Hearing segment and contributes to revenue growth, even though hearing instruments remain the dominant business. On SIX Swiss Exchange, Sonova Holding AG stock trades in Swiss francs under ISIN CH0012549785; analysts closely watch how products such as the Momentum 4 Wireless support diversification of earnings.
