The Sennheiser Momentum 5 has BIG UPGRADES... but are they enough?

Sennheiser's Momentum 5 is finally here, coming in at $400. While its predecessor, the Momentum 4, sounded pretty good, it fell short in areas that a premium noise-canceling headphone —namely, the ANC quality—should deliver on. With the Momentum 5, Sennheiser claims they've leveled up the ANC meaningfully, making it a true competitor to giants like the Sony WH1000-XM6, AirPods Max 2, or Bose QC Ultra Gen 2.

But after extensive testing, including getting opinions from multiple friends on a recent trip I took, deciding whether this is the absolute best buy in the $400 bracket is surprisingly complicated.

Build, Design, Comfort, Accessories & Features

Starting with the build and design, the Momentum 5 shares a lot of DNA with the Momentum 4 and the HDB 630. It features a similarly no-nonsense chassis with a  textured cloth-like material on the headband, and for that reason the look is fairly uncontroversial here and I have no issues with it. For the most part, it is comfortable enough to wear through a full workday, however, the ear cups are still a bit on the small side, meaning my ears do touch the inside of the baffle.

Due to the headband design, Momentum 5 (like the HDB 630 & Momentum 4) also lacks a mechanism to center the headphones on your head perfectly—they can kind of be off-centered on the Y-axis if you're not careful/precise—which can occasionally lead to wearing them asymmetrically.

The real star of the physical package, however, is the new carrying case. It’s smaller, features a brilliant built-in handle, and finally makes the Momentum series competitive with Bose for travel convenience (even if the Bose's case is still technically a slightly smaller footprint).

Where the Momentum 5 makes its biggest leap is yes, in its Active Noise Canceling. Thanks to a significantly improved microphone array (four microphones instead of two), the ANC is vastly better than the Momentum 4 and is now genuinely competitive with class leaders like the Bose QC Ultra Gen 2 and Sony WH-1000XM6 (though I still give Sony the slight edge for pure ANC).

When you combine this top-tier ANC and solid comfort profile with a staggering (user-replaceable!) battery life of just under 60 hours, the Momentum 5 emerges as a truly solid entry for frequent travelers, at least when it comes to quality of life features and user experience (UX). 

Momentum 5 also features an upgraded ambient mode, a highly effective wind-cut filter, and Dolby Atmos support (with head tracking promised in a future update).

Sound

When it comes to sound quality, the story is a bit more complicated. The Momentum 5, much like its predecessor, has tons of sub-bass, but its actually even more than the Momentum 4 had.

For some, this thunderous low-end is exactly what they want from a travel headphone, but I find it a bit overbearing and loose compared to the tighter, more tonally rich bass of the slightly more expensive HDB 630, for example.

The midrange and treble are generally well-balanced and crisp sounding without being fatiguing, but there are still moments of edginess and incoherence that the HDB 630 manages to avoid, likely due to the differences in treble tuning.

The biggest frustration, however, is that unlike the HDB 630, which was built with Parametric EQ (PEQ) in mind, the Momentum 5 only offers a basic 8-band fixed Graphic EQ. This severely limits your ability to correct specific resonances on your own head, meaning if the default sound profile doesn't perfectly suit your anatomy, you are more stuck with it than you would be with the HDB 630—which arguably sounds better stock anyway, and shares the same comfort/build/design profile for the most part.

Conclusion

So, who is this headphone actually for?

If your absolute maximum budget is $400, or you are upgrading from an older Momentum generation, the Momentum 5 is an obvious choice that easily beats out the Sony WH-1000XM6 and absolutely mops the floor with the Apple AirPods Max.

However, if you are willing to spend slightly more, things get tricky. The Bose QC Ultra Gen 2 ($450) offers a potentially more comfortable fit, comparable ANC, and its "CustomTune" feature intelligently snapshots the sound of the headphone as it actually performs on your head and adjusts a few things to make it sound more natural.

Furthermore, if sound quality is your ultimate priority, spending an extra $100 on the HDB 630 gets you a more refined default tuning, a better dongle, and the essential Parametric EQ.

So for me, the Momentum 5 isn't quite a world-beater, and thus it earns a 5.1 for sound quality, placing it right between the Bose QC Ultra Gen 2 (4.8) and the HDB 630 (5.4). It is a solid headphone, but in a highly competitive market, I'm not sure anyone would call it an undisputed king.
