Sennheiser Momentum 4 Wireless headphones on a desk" width="1200" height="800" loading="lazy" style="height:auto">
Battery life is the quiet battleground of premium headphones. Most flagship models manage around 30 hours of Noise Cancelling play, which is fine for a week of commutes but requires a recharge ritual. Sennheiser took a different path with the Momentum 4: it pushed the battery to 60 hours while keeping the refined sound signature the brand is known for. That number is the headline, but it is not the only reason to consider these headphones. After several weeks of daily listening, travel, and work calls, I can report on whether the Momentum 4 earns its price in a crowded market.
Before the details, a standard note. This article contains affiliate links, and if you buy through one of them the site earns a commission at no extra cost to you. That commission does not change what I test or recommend, and the headphones in this review were used the way a normal owner would use them.
The Momentum 4 sits at the top of Sennheiser's consumer lineup. It is an over ear, wireless headphone with adaptive noise cancellation, Bluetooth 5.2, and a design that trades the retro styling of its predecessor for a cleaner, more modern look. This review covers the build, the sound, the ANC, the battery claim, and the software that ties it together.
Design and Build
The Momentum 4 abandons the cloth and metal basket look of the Momentum 3 in favor of a smooth, minimalist shell. The headband is padded and adjustable, and the earcups are plush with generous cushioning. At about 293 grams, it is not the lightest headphone on the market, but the weight distribution is excellent, and I wore it for several hours without the pressure points that cheaper cans develop. The overall feel is premium without being flashy.
Build quality is reassuring. The hinges feel solid, the earcup swivels are firm, and the materials resist fingerprints better than glossy competitors. The controls are split between the right earcup, with playback and volume touch controls, and a dedicated power switch and ANC button on the other side. A USB-C port handles charging, and there is a 2.5 millimeter input for wired listening if you ever run out of battery.
The carrying case is a soft shell pouch rather than the hard case some rivals ship, which is a small downgrade in protection. The headphones fold flat for storage, and the pouch fits them comfortably. It is a minor point, but at this price the accessory detail is worth noting.
Key Features
The 60 hour battery is the marquee feature. Sennheiser rates the Momentum 4 for up to 60 hours of playback with noise cancelling on, and a quick charge adds several hours in ten minutes. In a market where 30 hours is the norm, doubling that number removes the charger from your daily routine. I will discuss how close my testing came to the claim shortly.
The second feature is hybrid adaptive noise cancellation. The system uses microphones to sample the environment and adjusts cancellation in real time, with four transparency modes for when you need to hear the world. Bluetooth 5.2 supports SBC, AAC, and aptX Adaptive, so Android users get high quality wireless audio, and the multipoint connection lets the headphones pair with two devices at once.
The 42 millimeter drivers deliver the signature Sennheiser tuning, warm and detailed with a slight emphasis on the low end. The companion app, Sennheiser Smart Control, adds a five band EQ, sound zones, and firmware updates. There is no spatial audio here, which some rivals now offer, so the Momentum 4 stakes its claim on sound quality and endurance rather than processing tricks.
Real-World Performance
The sound is the reason to buy these headphones. The Momentum 4 has a balanced, musical signature that handles vocals and instruments with real clarity. Bass is present and warm but not boomy, mids are forward without being shouty, and treble is smooth rather than sharp. I listened to everything from jazz to electronic music, and the headphones never sounded harsh or muddy. The soundstage is wide for a closed back design, which gives music a sense of space that most wireless cans lack.
The battery claim held up in my testing. I used the headphones for two weeks without charging, mixing music playback, podcasts, and calls, and the battery indicator never dropped below half. That matches the 60 hour rating in real conditions with moderate volume. It is the rare case where a headline spec translates directly into everyday convenience.
Noise cancellation is good but not class leading. It tames the low rumble of an airplane cabin and the drone of an office HVAC system effectively, and conversation is reduced to a murmur. Compared to the very best ANC on the market, there is slightly more residual noise, and the transparency mode sounds a touch artificial. In practical terms, the ANC is strong enough for most travel and work situations, just not the absolute best.
Call quality was better than I expected for a headphone that does not market itself as a headset. The microphones picked up my voice clearly on office calls, and the person on the other end reported only mild background noise. The touch controls responded reliably, and the auto pause when you remove the headphones worked every time. The Bluetooth connection stayed rock solid at typical room distances.
The one recurring irritation is the touch control layout. The swipe gestures on the right earcup are easy to trigger accidentally when adjusting the headphones, which occasionally paused music or changed volume. It is a learned behavior rather than a dealbreaker, but it happened often enough to mention.
Pros and Cons
Pros:
- 60 hour battery life removes daily charging
- Warm, detailed, genuinely musical sound
- Comfortable for long listening sessions
- Solid ANC for travel and office use
- aptX Adaptive support for Android devices
- Reliable call quality and multipoint pairing
- Fast charging adds hours in ten minutes
Cons:
- ANC is good but not the best in class
- Touch controls trigger accidentally at times
- Soft shell case instead of a hard case
- No spatial audio processing
How It Compares
The Momentum 4 competes against the flagship noise cancelling headphones from Sony and Bose. The table below compares the three on the features that matter most.
| Feature | Sennheiser Momentum 4 | Flagship Sony | Flagship Bose |
|---|---|---|---|
| Battery life | Up to 60 hours | Up to 30 hours | Up to 24 hours |
| Sound signature | Warm, balanced | Punchy, adjustable | Neutral, detailed |
| ANC strength | Strong | Best in class | Best in class |
| Codec support | aptX Adaptive, AAC | LDAC, AAC | AAC only |
| Multipoint | Yes | Yes | Yes |
| Spatial audio | No | Yes | Yes |
If ANC supremacy is your priority, the Sony and Bose models edge ahead, and both add spatial audio. If battery life and musicality matter more, the Momentum 4 wins decisively on endurance and matches or beats both on raw sound quality. For an independent technical assessment of these headphones, RTINGS has a detailed lab test of the Momentum 4 worth reading.
Who Should Buy It
The Momentum 4 is for listeners who prioritize long battery life and rich sound over absolute noise cancellation. It suits frequent flyers who want to skip mid flight charging, office workers who listen through a full day, and anyone who simply loves the way music sounds through a well tuned driver. The aptX Adaptive support also makes it a natural fit for Android users.
Skip it if you demand the strongest ANC on the market or if spatial audio is a must have for your movie watching. For everyone else, this is one of the best balanced flagship headphones available. You can check the current price of the Sennheiser Momentum 4 on Amazon if you are ready.
How We Test
I tested the Momentum 4 over several weeks of daily use, including music listening, podcasts, work calls, and travel. I measured battery life through normal use rather than a fixed test, and I evaluated ANC in an office, a café, and near a busy road. I compared the sound against two flagship competitors and assessed comfort over multi hour sessions.
I did not run an audio lab analysis, and battery results vary with volume and codec. For a deeper look at how headphone testing is done, SoundGuys explains its headphone testing methodology. The Momentum 4 is listed on Amazon if you want to see the current price.
