Sennheiser Momentum 4 Wireless Review — A legacy audio brand trades its retro styling for a conventional look, but secretly packs in monster battery life and superior sound to challenge the mainstream king

Sennheiser's Momentum 4 packs a staggering 60-hour battery life that completely embarrasses the Sony XM5. While the rest of the industry is busy chasing incremental gains in noise cancellation, Sennheiser decided to solve the one problem that actually ruins your day: the constant anxiety of a dead battery.

What you're actually getting

The Momentum 4 is a departure from the quirky, retro-industrial aesthetic of its predecessors, opting for a more conventional, streamlined look. Some might call it boring, but after living with these for months, I call it functional. They feel like a premium tool rather than a fashion accessory. The build quality is solid, and the comfort is genuinely best-in-class. As Digital Trends noted, "The ear pads are luxuriously soft and squishy and when I put them on they are instantly comfortable." You can wear these for an entire workday without that dreaded "clamping" fatigue that plagues so many other flagship cans.

Under the hood, you’re getting a sound profile that prioritizes engagement over clinical flatness. It’s a fun, punchy signature that makes modern production shine without burying the midrange in mud. While the Sony XM5s might have the edge in pure, surgical noise cancellation, the Momentum 4s offer a more natural, expansive soundstage that feels less "closed-in."

The real secret weapon here is the USB-C implementation. Being able to plug these directly into your laptop for lossless audio while simultaneously charging is a feature I didn't know I needed until I had it. As SoundGuys put it, "I'm going to have to give it to the Sennheiser Momentum 4 Wireless simply for the USBC audio alone." It’s a massive quality-of-life upgrade for anyone working at a desk.

Sound — what reviewers actually heard

The Momentum 4 isn't just about endurance; it’s about musicality. Here is how the performance breaks down:

Where it actually wins

The battery life is the headline, but it’s the consistency that makes these a winner. You aren't just getting a big number on the box; you're getting a pair of headphones that you can throw in your bag on a Friday and not worry about charging until the following weekend.

The comfort is the other major victory. Sennheiser nailed the weight distribution. Flossy Carter hit the nail on the head when he said, "These are braces soft. They feel like a nice set of braces." They disappear on your head, which is the highest compliment you can pay to a pair of over-ear headphones. Combined with a hard-shell case that actually protects the gear—unlike some of the flimsy pouches shipping with competitors—it’s a package that feels built for the real world.

Where it falls short

It isn't all perfect. The touch controls are a bit too eager to please; I’ve accidentally paused tracks or skipped songs just by adjusting the headband. It’s a minor annoyance, but one that persists even after months of use.

Then there’s the portability issue. The ear cups don't fold. This means the carrying case, while well-designed, takes up significantly more room in your backpack than a pair of folding headphones. If you’re a minimalist traveler, this is a genuine friction point. Furthermore, the ANC is perfectly adequate for an office or a commute, but if you’re looking for the absolute "black hole" silence that the Sony XM5s provide on a jet engine, you’ll find the Momentum 4s slightly lacking. The companion app also feels like it’s playing catch-up, lacking the polish and feature depth of the market leaders.

Should you buy it?

Buy if you

• Value battery life above all else and hate the "low battery" chime.
• Want a fun, engaging sound signature that makes music feel alive.
• Spend a lot of time at a desk and want to utilize USB-C lossless audio.
• Prioritize long-term wearing comfort for 8+ hour sessions.

Skip if you

• Are a frequent flyer who needs the absolute strongest ANC on the market.
• Have limited space in your carry-on and need headphones that fold down into a tiny footprint.
• Prefer a highly customizable app experience with deep EQ and feature sets.

The Sennheiser Momentum 4 Wireless deliver class-leading battery life and superior sound quality that make them a formidable alternative to Sony's flagship.
