Two premium over-ear headphones, two different philosophies. The Sony WH-1000XM6 leans on class-leading noise cancellation and wireless flexibility, while the Sennheiser MOMENTUM 5 Wireless counters with longer battery life and a more traditional tuning. Neither is a clear winner on paper, so this head-to-head works through the specs and scores to see where each genuinely excels and where the gap is smaller than marketing suggests.
Price and positioning
Both sit at the top of the over-ear market, and their prices reflect that. The Sony WH-1000XM6 costs $398, the Sennheiser MOMENTUM 5 Wireless $400. That $2 difference is negligible, so price alone will not decide this. What differs is what each brand asks you to accept. Sony positions the XM6 as the travel companion: light at 254g, with adaptive ANC tuned for planes and offices. Sennheiser positions the MOMENTUM 5 as the long-haul listener's choice, with a 57-hour battery that outlasts most flights and work weeks. Neither has a water or dust resistance rating, so if you need something for the gym or rain, look elsewhere in our over-ear guide.
The scores, side by side
The HearWiki scores are closer than the hype suggests. The Sony WH-1000XM6 scores 86/100, the Sennheiser MOMENTUM 5 Wireless 82/100. That four-point gap is real but modest. Dig into the subscores and the picture gets more interesting. Sony leads on ANC (8.5 vs 8.0) and calls (7.0 vs 6.5), while Sennheiser takes sound (8.5 vs 8.0) and battery (9.5 vs 7.5). Both tie on value at 7.5. So the headline score favours Sony, but it is not a landslide. If your priorities are sound quality and endurance, the Sennheiser's lower overall score may not bother you. For a full breakdown of every subscore, see the comparison table.
Sound
Sennheiser has the edge here, but it is not a knockout. The MOMENTUM 5's 42mm dynamic driver delivers a detailed, well-balanced signature with a wide frequency response. It is the kind of tuning that flatters acoustic music, jazz and vocals without exaggerating bass. The Sony WH-1000XM6, with its 30mm driver, is more neutral and slightly less resolving, scoring 8.0 against the Sennheiser's 8.5. Neither is bad; they just aim at different listeners. If you want warmth and texture, the Sennheiser is the safer bet. If you prefer a cleaner, more analytical sound, the Sony will satisfy. Both support high-quality wireless codecs, but they take different routes: Sony offers LDAC, while Sennheiser offers aptX Lossless. Neither is universally supported across all phones, so check your device before buying.
Noise cancelling and battery
The Sony WH-1000XM6 is the noise cancelling champion here, scoring 8.5 against the Sennheiser's 8.0. Its adaptive ANC is class-leading, and the 12-microphone array helps both cancellation and transparency mode. The Sennheiser's hybrid adaptive ANC is good but not quite as aggressive; it will handle office chatter and traffic, but the Sony is more effective at silencing the world. Battery life flips the script. The Sony offers 40 hours with ANC off, but drops to 24 hours with ANC on. The Sennheiser MOMENTUM 5 Wireless delivers 57 hours with ANC on, a massive advantage for commuters who forget to charge. If you fly weekly or work long shifts, the Sennheiser's endurance is hard to ignore. Both use modern Bluetooth (5.3 on Sony, 5.4 on Sennheiser) and support multipoint, so you can pair two devices at once.
Calls and everyday use
The Sony WH-1000XM6 is the better call headphone, scoring 7.0 against the Sennheiser's 6.5. Its microphone array is clearer in noisy environments, and the transparency mode is more natural. The Sennheiser is not bad, but you may need to speak up in windy or crowded spaces. Controls differ too. The Sony uses physical buttons only, which some prefer for reliability, while the Sennheiser offers touch controls on the ear cups. Neither is a dealbreaker, but if you take calls in loud places, the Sony is the safer pick. Both are comfortable for long sessions, though the Sony is lighter at 254g. If you are comparing against other options in this class, our best over-ear list is worth a look.
Which one should you buy?
Buy the Sony WH-1000XM6 if you prioritise noise cancellation and call clarity. It is the better travel companion, lighter on the head and more effective at blocking out the world. The 24-hour battery with ANC is enough for most days, and LDAC support is a plus if you own a compatible Android phone. Buy the Sennheiser MOMENTUM 5 Wireless if you value sound quality and battery life above all else. The 57-hour runtime means you can charge it once a week, and the warmer tuning is more engaging for music lovers. If you are torn, consider your daily routine: if you are on planes or in open offices, the Sony wins; if you are at a desk or on long train rides, the Sennheiser may serve you better. Both are excellent, and the four-point score gap should not be the deciding factor.
