In the world of premium wireless headphones, few names carry as much weight as Sony and Sennheiser. With the release of the Sony WH-1000XM6, the latest iteration of Sony’s wildly popular ANC series, the bar for active noise-canceling headphones has been raised yet again. But the Sennheiser Momentum 4, still a standout nearly two years after its release, remains a formidable competitor with its audiophile-grade tuning and marathon battery life.
If you’re shopping for a top-tier pair of Bluetooth headphones in 2025, you’re likely considering one of these two. So, how do they stack up? Let’s compare the Sony WH-1000XM6 and Sennheiser Momentum 4 across build, features, sound quality, ANC performance, and value.

Look & Feel
The Sony WH-1000XM6 evolves the XM5’s minimalist aesthetic with even softer ear cushions and improved clamping force distribution. The build remains lightweight, with a subtle premium texture across the matte plastic. Comfort is noticeably enhanced thanks to deeper padding, making it better suited for extended listening sessions. In comparison, the Sennheiser Momentum 4 has a sleeker, more business-like design. It’s lighter than it looks, and the low clamping force makes it a favorite for travel and all-day use. Sony feels slightly more refined in fit, but the Momentum 4 is no slouch, especially for long-haul flights or office work.
Design & Functionality
In terms of interfacing with these headphones, the XM6 is more advanced than the Momentum 4 in more ways than one. Both headphones have a touch sensor interface, but the XM6 is way more responsive. This is especially true when it comes to volume control, where the XM6 is a lot more tactile with than the Momentum 4. Then there’s noise canceling, where it should come as no surprise which headphone is superior. The Momentum 4 makes a good effort, but Sony is the industry leader for a reason. Compared to the Momentum 4, the XM6 is dead quiet.
If you’re looking for the smartest headphone with the most customization options, Sony takes the crown. With Speak-to-Chat, Adaptive Sound Control, and integration with Sony’s Headphones Connect App, you can tailor everything from the ANC level to EQ, 360 Reality Audio, and even head tracking. The Sennheiser Momentum 4 is simpler in comparison, which you might prefer, but Sennheiser’s Smart Control app also offers a capable EQ and firmware updates, though it’s not as robust or intuitive as Sony’s software suite.
Bluetooth
Another area where Sony outplays Sennheiser is with its Bluetooth connection. Both headphones have high stability and fast pairing, but the XM6 is one set above the Momentum for with support from version 5.3 instead of 5.2. The XM6 also features multipoint, as well as better CODECs for Android devices like LDAC and LC3.
Battery Life
It’s very clear which headphone is superior here. the Momentum 4 outclasses a lot of headphones with its 60 hour battery life, even Bluetooth headphones that are twice as expensive as it. The XM6 only provides up to 30 hours of playtime, which is disappointing considering which one is higher in price. This is a special case though, considering there are tons of flagship headphones out there that cant match the Momentum 4’s endurance.
Soundstage
What’s going to make the Sony XM6 stand out in front of the Sennheiser Momentum 4 in terms of soundstage is its spatial audio. This is more of a significant advantage compared to past models, since Sony’s 360 Reality Audio can now be used with all audio on your device. However, when you compare their standard stereo imaging, it’s easier to see which headphone comes out on top. While the XM6 has a slightly wider than average soundstage with good instrument placement, the Momentum 4 is more expansive. Its ability to layer instruments is much more precise than the XM6, giving it an edge when it comes to certain genres like jazz and classical music.
Low End
It’s easy to be won over by the bass on the XM6, with its full bodied response and warmth. Although it can be tweaked, the bass will still appear boomy compared to the tight grip of the Momentum 4 lows. While it leans more neutral in timbre than the XM6, the Momentum 4 offers a more solid punch that provides more clarity for individual performances.
Mids
If you’re looking for refined midrange clarity over Bluetooth, the Momentum 4 is the best choice. The midrange over the XM6 is smooth, but recessed in comparison. However, if you prefer a headphone tuned for easy listening, the XM6 will do its job. Those looking for better separation and refined sound elements, the Momentum 4 is the right choice.
Highs
Both headphones have good treble that easy to consume without venturing into harsh territory. The XM6 has the smoothest highs between the two, but some might consider it too relaxed for their tastes. You get more open, airy highs on the Momentum 4, with more clarity and shimmer to enjoy.
Summary
The Sony WH-1000XM6 and Sennheiser Momentum 4 represent two different philosophies in premium noise-canceling headphone design. Sony’s WH-1000XM6 excels in smart features, call quality, and best-in-class ANC, making it ideal for users who want a seamless, tech-driven listening experience with plenty of customization. On the other hand, the Sennheiser Momentum 4 offers a more refined sound signature, dramatically longer battery life, and excellent comfort, all at a slightly lower price.
In 2025, the choice between these two titans comes down to priorities. If you’re looking for cutting-edge noise cancellation, intelligent software, and polished everyday usability, Sony’s WH-1000XM6 is the clear winner. But if you’re an audiophile or frequent traveler who values sound quality and endurance above all, the Sennheiser Momentum 4 might just be the better long-term companion.
