Sennheiser Momentum 4: The Noise-Cancelling Headphones Everyone Keeps Comparing to Bose and Sony

Sennheiser Momentum 4 takes the brand’s legendary sound and wraps it in all?day comfort, huge battery life, and smart noise cancelling. If you’re tired of choosing between rich audio and real-world usability, these over-ears aim to be the one pair that finally does it all.

You know that moment on a flight when the engines roar, the cabin hums, a baby starts crying three rows back, and your music suddenly feels like background noise to the chaos? Or the open-plan office where every Teams call, every keyboard, every espresso shot at the coffee bar lands directly in your brain? That constant sonic fatigue isn’t just annoying – it’s exhausting.

Most headphones promise to fix it. Many sound great in a quiet living room, then crumble the second you step onto a train or into a busy street. Others block noise well but flatten your music into something lifeless and compressed. And then there are the batteries that tap out just when you actually need them.

This is the gap the Sennheiser Momentum 4 tries to fill: serious audiophile-grade sound, real-world active noise cancelling, and battery life that doesn’t panic you every time you travel.

The Solution: What Sennheiser Momentum 4 Is Trying to Be

The Sennheiser Momentum 4 Wireless (part of the Sennheiser consumer audio portfolio now owned by Sonova Holding AG, ISIN: CH0012549785) is Sennheiser’s flagship noise?cancelling over-ear headset aimed directly at Bose QuietComfort and Sony WH?1000XM series fans. It’s built for people who want:

• High-end, detailed sound for music, movies, and calls.
• Effective noise cancelling that adapts to your surroundings.
• Battery life measured in days, not hours, with fast charging as backup.
• Comfort you can wear through a workday and long-haul flights without ear or head pain.

On paper and in most real-world reviews, it delivers on a surprising number of those promises – with a very specific personality that you need to be okay with.

Why this specific model?

If you have even a passing interest in headphones, you know the usual hierarchy: Bose for comfort and noise cancelling, Sony for features and strong ANC, and Sennheiser for pure sound quality. The Momentum 4 is Sennheiser’s attempt to pull all three pillars together.

Here’s what sets it apart, based on specs and real user feedback from reviews and discussions:

• Signature Sennheiser sound, but more neutral than before. The Momentum 4 uses large dynamic drivers tuned with a clean, detailed profile. Compared to some earlier Momentum models that leaned heavier on the bass, this generation is generally described as more balanced: solid low-end, clear mids (vocals, guitars), and airy treble. Most listeners find it less boomy than many consumer ANC rivals.
• Very long battery life. Across reviews and user reports, one consistent highlight is runtime. People routinely talk about going multiple workdays or several flights without recharging, which changes how you use them – you’re no longer glued to a battery indicator.
• Comfort built for all-day wear. The redesign from the older, more retro Momentum models to a smoother, more understated look wasn’t just cosmetic. The clamp force and cushion design are widely reported as comfortable for long sessions, even for users who wear glasses.
• Adaptive noise cancelling and transparency. The Momentum 4 uses hybrid ANC with ambient/transparency modes. ANC effectiveness is frequently compared to Sony and Bose; most people put it just a hair behind the absolute best in cancelling airplane engines and office noise, but close enough that many prefer the trade-off for better sound quality.
• Solid app and EQ control. Through Sennheiser’s app, you can adjust EQ, toggle ANC modes, and tweak features. This is key: out of the box, the tuning already pleases most users, but the app lets you customize it if you want more bass or brightness.

In other words: if Bose is the king of silence and Sony is the king of features, Momentum 4 tries to be the king of listening pleasure without sacrificing the stuff that actually makes wireless headphones practical.

What Users Are Saying

Dig through Reddit threads and user reviews and a clear pattern emerges around the Sennheiser Momentum 4:

Most-loved aspects:

• Sound quality. This is the single biggest reason people pick the Momentum 4 over Bose and sometimes even over Sony. Owners often describe the sound as more natural and less processed, with good instrument separation and a tuning that works well for everything from electronic to jazz.
• Battery life. People talk about forgetting when they last charged the headphones. For frequent travelers, this is a game-changer.
• Comfort. Many users report wearing them through a full office day or multiple movies on a flight without pain. For glasses wearers, pressure is often described as mild and manageable.
• Connection stability. Reports of random dropouts are relatively rare; most users describe the wireless link as reliable for everyday use.

Common complaints or trade-offs:

• ANC slightly behind the very best. The Momentum 4’s noise cancelling is good to very good, but when directly compared to top-end Bose and Sony, hardcore ANC fans sometimes find it a step behind in killing low-frequency engine noise.
• Touch controls aren’t for everyone. Some users prefer physical buttons and mention that swipes and taps can occasionally misfire, especially in the rain or when adjusting the fit.
• Design shift from "retro" to minimalist. A portion of long-time Sennheiser fans loved the previous Momentum’s visible metal rails and vintage look. The Momentum 4’s smoother, more generic design doesn’t excite everyone visually, even though it improves comfort and portability.
• App learning curve. The app is powerful but can feel a bit busy at first; some users ignore advanced features and just stick to basic ANC and EQ once they find a profile they like.

Alternatives vs. Sennheiser Momentum 4

The premium ANC headphone market is brutally competitive, and the Momentum 4 lives right in the thick of it.

• Versus Bose QuietComfort / QC Ultra: Bose still tends to win for pure noise cancelling and effortless comfort. If blocking the outside world on long flights is your #1 goal, Bose might edge ahead. But many listeners feel Bose’s sound is more relaxed and less detailed than the Momentum 4.
• Versus Sony WH?1000XM series: Sony typically leads on features – think extensive customization, multipoint, and strong ANC. Sony’s sound is fun and bassy, but some listeners consider it more "consumer" tuned. Sennheiser Momentum 4 often gets the nod from people who prioritize a more refined, slightly more neutral sound signature.
• Versus Apple AirPods Max: Apple’s option plays strongly in the Apple ecosystem with tight integration and excellent spatial audio, but it’s heavier and significantly pricier. Momentum 4 is usually favored for comfort and value, especially outside of all?Apple setups.
• Versus budget ANC headphones: There are plenty of cheaper ANC headphones that deliver "good enough" performance, but the jump to the Momentum 4 is about consistency: better sound, much better build feel, more reliable noise cancelling, and that huge battery cushion.

In short, if noise cancelling perfection is all you care about, Bose might be your top pick. If smart features and deep customization rank first, Sony is a compelling rival. But if sound quality plus battery life plus comfort is your trifecta, the Momentum 4 stands out as a particularly balanced choice.

Final Verdict

There’s a quiet kind of luxury in putting on a pair of headphones and having the world just…fade. Not because the sound is cranked to painful levels, but because the tuning is so satisfying and the noise cancelling is competent enough that you can breathe a little easier, focus a little better, enjoy your music a lot more.

The Sennheiser Momentum 4 delivers that for a specific type of listener: someone who cares deeply about how their music feels, but who also lives in the real world of deadlines, video calls, and long-haul travel. It doesn’t scream for attention; it just sounds excellent, lasts a very long time on a charge, and stays comfortable for as long as you need it.

Are there headphones with slightly better active noise cancelling? Yes. Are there models with even more software tricks? Also yes. But most users don’t need the absolute edge case – they need a pair that will reliably sound wonderful every single day.

Backed by the audio heritage now housed under Sonova Holding AG and sitting alongside hearing technology brands like Phonak (see phonak.com), the Sennheiser Momentum 4 feels like the natural evolution of a brand that’s spent decades obsessing over how we hear.

If you want one set of wireless over-ears that you can commute with, fly with, work with, and still savor late?night listening sessions at home, the Momentum 4 deserves a very serious listen.
