The Sennheiser Momentum 4 - Sonova bets on long-haul comfort

The Sennheiser Momentum 4 rests on a tray of brushed aluminum in a Zurich studio, its fabric headband cool under the fingers and the earcups swiveling with a soft click as product manager Laura Meyer adjusts them for yet another test fit.
Adaptive ANC for daily commuters
Sonova uses the Sennheiser Momentum 4 to push deeper into consumer audio with an over-ear headphone designed for commuters, remote workers and frequent flyers. The model offers hybrid adaptive noise cancelling with an array of microphones that continuously sample ambient sound. On a busy tram or in an open-plan office, the ANC automatically shifts strength to block low engine hum while leaving higher-pitched voices less muffled.
Battery life is one of the Momentum 4’s central promises: Sennheiser specifies up to 60 hours of playback with ANC active, measured at moderate volume with SBC codec over Bluetooth. In practice, that means several full work weeks of mixed commuting and video calls before a USB-C recharge. A 3.5 mm analog cable included in the box allows passive listening when the battery is drained, a practical detail for long train journeys.
Sonova and Sennheiser Momentum 4 in the portfolio
Explore how Sonova’s consumer audio line, including the Momentum 4, fits alongside its hearing solutions and affects its equity story.
Design, comfort and controls
The Momentum 4 shifts away from the metal-sliding headband of the Momentum 3 to a lighter, more plastic-centric construction with cushioned ear pads and a fabric-covered headband. At roughly 293 g, it sits in the mid-field of over-ear weight, lighter than some studio models but heavier than ultra-light travel sets. In use, the clamping force feels moderate, and the oval pads distribute pressure evenly, which matters for several hours of back-to-back video calls.
Controls are centered on the right earcup with a capacitive touch surface for swipes and taps. Volume adjustment, track skipping and ANC mode changes rely on finger gestures rather than physical buttons. Sennheiser couples this with wear detection: removing the headphone pauses playback automatically, helped by sensors in the earcup. For users who prefer physical feedback, basic functions like power and Bluetooth pairing still have discrete buttons on the rim.
Sound profile and customization
Out of the box, the Momentum 4’s tuning leans toward a warm, slightly bass-forward profile, aligned with mainstream consumer preferences. Reviews from specialist outlets such as RTINGS and What Hi-Fi describe extended low frequencies without muddying mids, and a clear but not sharp treble response that keeps cymbals present but avoids harshness for long listening sessions. Compared to Sennheiser’s more neutral audiophile lines, the Momentum 4 aims at casual listening, streaming and phone calls.
Sonova and Sennheiser supply an app-based equalizer in the Sennheiser Smart Control app, available for Android and iOS. Users can select presets like “Bass Boost” or “Podcast” or define custom EQ curves per device. Sound zones in the app allow geolocation-based profiles, such as a quieter ANC mode at home and stronger suppression in the metro. The app also handles firmware updates, bringing incremental improvements in ANC and connectivity since launch, as documented in Sennheiser’s release notes.
Codec support includes SBC and AAC alongside aptX Adaptive, serving both mainstream smartphone users and those with compatible Qualcomm chipsets. For lossless-focused listeners, the lack of LDAC is a known trade-off, but the combination of aptX Adaptive and a wired mode gives flexibility. Maximum Bluetooth 5.2 range typically covers a medium apartment or office floor, with multipoint pairing enabling connections to a laptop and phone simultaneously.
Integration into Sonova’s consumer strategy
Sonova took over the Sennheiser consumer audio business in 2022, adding headphones like the Momentum 4 to a portfolio previously dominated by hearing aids and cochlear implants. CEO Arnd Kaldowski has repeatedly highlighted the strategic logic: reaching younger, healthy-hearing customers early and building brand familiarity before they need hearing solutions. Headphones with strong ANC also overlap technically with Sonova’s core signal-processing competencies.
The Momentum 4 is positioned as an upper mid-range wireless over-ear, priced around 349 EUR at launch in Europe, with market prices now often below that as retailers run promotions. Availability covers major online and physical electronics retailers in key markets such as Germany, Switzerland, the US and the UK, along with Sennheiser’s own online shop. Color options include at least black and white, with occasional limited finishes depending on region and retailer.
Beyond pure sales, the Momentum 4 provides Sonova with detailed usage data where customers opt in via the app: listening durations, ANC patterns and environment types help inform both headphone updates and, in aggregate, hearing product development. This feedback loop fits Sonova’s broader data-centric approach that Kaldowski and his team describe in investor presentations.
How the Momentum 4 compares
In the crowded ANC headphone segment, the Momentum 4 competes with models such as Sony WH-1000XM5, Bose QuietComfort Ultra and Apple AirPods Max. Specialist reviewers commonly rank its ANC slightly below Sony’s top performance but still strong enough to significantly reduce commuting noise. Its battery life, however, is frequently noted as a standout strength relative to those peers.
Comfort assessments vary by head shape, but many long-form reviews point out that the lighter construction and updated pads improve wearability over the Momentum 3, which some found heavy. For Sonova, this is more than a comfort metric: happy users who wear headphones for hours daily become an attractive target audience for subtle hearing protection messages and related services in the future.
Call quality, handled by beamforming microphones and noise reduction algorithms, is rated as solid for typical office and home environments. In wind or heavy traffic, some reviewers note occasional artifacts, a common issue across ANC headsets. Firmware updates after launch have aimed to refine this, again underscoring how software remains key to product competitiveness even after hardware release.
Stock context and financial angle
From a revenue perspective, the Momentum 4 sits inside Sonova’s Consumer Hearing segment, which the group reports separately from its traditional hearing instruments. The company describes this segment as a growth field with cyclic but attractive volumes, tied to lifestyle trends and device replacement cycles rather than strictly medical need. As Sonova expands distribution and co-marketing with Sennheiser, headphones like the Momentum 4 contribute to diversification of cash flows beyond regulated healthcare markets.
On the market, Sonova Holding AG stock (ISIN CH0012549785) trades on SIX Swiss Exchange, and the performance of products such as the Sennheiser Momentum 4 and the broader consumer audio line feeds into investor expectations for growth and margin resilience in the Consumer Hearing segment.
