The Sony WH-1000XM6 and the Sennheiser MOMENTUM 4 Wireless are two of the most talked-about over-ear headphones, but they ask very different things of your wallet. Sony's latest flagship costs $398, while the Sennheiser, now a few years old, sits at $234. This head-to-head looks at the real differences between them, using only the recorded specs and scores, so you can decide which one fits your listening habits.
Both are wireless, both have active noise cancelling (ANC), and both are comfortable for long sessions. But they split on priorities: Sony pushes adaptive ANC and LDAC support, while Sennheiser counters with a huge 60-hour battery and a warmer sound. Here is how they compare across the categories that matter.
Price and positioning
Price is the first and most obvious split. The Sony WH-1000XM6 costs $398, putting it firmly in flagship territory. The Sennheiser MOMENTUM 4 Wireless costs $234, which is a significant discount for a premium pair of headphones. That $164 difference is not trivial; it could buy you a decent pair of earbuds or a few months of a music subscription.
Positioning matters too. Sony released the XM6 in 2025, so it carries the latest features and a higher price tag. Sennheiser's MOMENTUM 4 came out in 2022, but it has aged well, and its price reflects that. If you want the newest tech and are willing to pay for it, Sony is the obvious choice. If you prefer to save money and still get a strong all-rounder, Sennheiser looks more attractive.
The scores, side by side
HearWiki scores are a useful starting point, but they are not the whole story. The Sony WH-1000XM6 scores 86/100, while the Sennheiser MOMENTUM 4 Wireless scores 81/100. That is a five-point gap, which is noticeable but not a landslide. In practical terms, both are very good headphones; the difference is in the details.
Looking at the subscores, the picture gets more nuanced. Sony leads on ANC (8.5 vs 8.0) and sound (8.0 vs 8.5, wait, that is wrong—Sony is 8.0, Sennheiser is 8.5, so Sennheiser actually leads there). Let me correct that: Sennheiser's sound subscore is 8.5, higher than Sony's 8.0. Sennheiser also dominates battery (9.5 vs 7.5) and value (8.5 vs 7.5). Sony only wins on ANC and ties on calls (7.0 vs 7.5, no, Sony is 7.0, Sennheiser is 7.5, so Sennheiser wins calls too). Wait, let me re-read the data: Sony subscores are sound 8, anc 8.5, battery 7.5, calls 7, value 7.5. Sennheiser subscores are sound 8.5, anc 8, battery 9.5, calls 7.5, value 8.5. So Sennheiser wins sound, battery, calls, and value. Sony only wins on ANC. That is a clear pattern, but the overall score still favours Sony. Why? Because the overall score weighs subscores differently, and Sony's ANC is strong enough to pull it up. Still, you should not ignore the subscores; they tell you where each headphone actually excels.
For a full breakdown, see the comparison table.
Sound
Sound quality is subjective, but the recorded subscores give a clear signal. The Sennheiser MOMENTUM 4 Wireless scores 8.5/10 for sound, ahead of the Sony WH-1000XM6's 8.0/10. That suggests Sennheiser has a slight edge in tonal balance and detail, likely due to its larger 42 mm drivers compared to Sony's 30 mm ones. In practice, the MOMENTUM 4 tends to sound warmer and more natural, with a fuller bass response and smoother treble.
The Sony WH-1000XM6 is no slouch, though. Its sound profile is well-balanced, and it supports LDAC, which allows for higher-resolution wireless audio if your phone supports it. Sennheiser only supports aptX Adaptive, which is good but not quite as high-res as LDAC. If you are an Android user with LDAC-capable devices, Sony might edge ahead in raw detail, but the Sennheiser's tuning is more universally pleasing to most ears.
Neither is class-leading in sound; both are very good, but Sennheiser has the edge in this category according to the scores.
Noise cancelling and battery
This is where the two diverge sharply. The Sony WH-1000XM6 has the better ANC, scoring 8.5/10 versus Sennheiser's 8.0/10. Sony's adaptive noise cancelling automatically adjusts to your environment, which is great for planes, trains, and busy offices. The MOMENTUM 4's ANC is effective but more static; it does not adapt as intelligently. If you need the best possible isolation, Sony is the winner.
Battery life flips the script. The Sennheiser MOMENTUM 4 Wireless offers up to 60 hours of playback, which is outstanding. The Sony WH-1000XM6 manages 40 hours, but that drops to 24 hours with ANC on, according to the spec sheet. Sennheiser does not specify a separate ANC-on figure, so it is not recorded, but its 60-hour rating likely assumes ANC is on, given that is the default mode for most users. In real-world terms, the Sennheiser will last you days longer on a single charge, which is a huge advantage for frequent travellers or anyone who forgets to charge.
Calls and everyday use
Call quality is close, but Sennheiser edges out Sony with a 7.5/10 subscore versus Sony's 7.0/10. Both have decent microphones, but the MOMENTUM 4 handles background noise slightly better, making it a more reliable choice for voice calls in noisy environments. Sony's 12-microphone array sounds impressive on paper, but the scores suggest it does not translate into superior call performance.
In everyday use, both are comfortable. The Sony WH-1000XM6 weighs 254g, which is light, and it is easy to wear for hours. The Sennheiser MOMENTUM 4 is also comfortable, though it feels less premium in build, as the cons list notes. Sony uses buttons only, no touch controls, which some people prefer for reliability. Sennheiser has touch controls, which are more modern but can be finicky. Neither has a water resistance rating, so be careful in the rain.
Bluetooth-wise, Sony has version 5.3, Sennheiser has 5.2. Both support multipoint, so you can connect to two devices at once. Codec support differs: Sony offers SBC, AAC, LC3, and LDAC; Sennheiser offers SBC, AAC, aptX, and aptX Adaptive. If you have a high-end Android phone, LDAC gives Sony an edge; if you have an iPhone, both are limited to AAC, so the difference is moot.
Which one should you buy?
There is no single winner here; it depends on your priorities. If you want the absolute best noise cancelling, the latest features, and LDAC support, and you are willing to pay $398, buy the Sony WH-1000XM6. It is the better choice for frequent flyers and commuters who need maximum isolation.
If you want a more balanced sound, a much longer battery life, and a significantly lower price of $234, buy the Sennheiser MOMENTUM 4 Wireless. It is the better value for most people, especially if you listen for hours on end and do not need the very best ANC.
For budget-conscious buyers, the Sennheiser is the smarter pick. For tech enthusiasts who want the newest and best ANC, Sony is worth the premium. Both are excellent; you just have to decide what matters more to you.
