Sennheiser MOMENTUM 4

The Sennheiser MOMENTUM 4 Wireless headphones are audiophile-grade in sound and battery, packing a remarkable 60-hour runtime and a natural, immersive soundstage. The noise cancellation is strong but not class-leading, and the earcups can feel cramped for larger ears, so comfort isn't a sure thing. Overall, it's an excellent pick for critical listening at or under $350, as long as you don't need the very best ANC or the roomiest fit.

Our lab measurements put the MOMENTUM 4's sound signature right up there with the best wireless headphones we've tracked. The frequency response is impressively neutral with a slight bass lift that doesn't muddy the mids. In percentile terms, sound quality falls into the 98th percentile, meaning it's essentially best-in-class for its type. The active noise cancellation also scores at the 98th percentile. It won't erase the drone of a jet engine like the Bose QC Ultra does, but it handles office chatter and street noise with very little impact on the music's character.

Battery life is another standout: 60 hours with ANC on is a number very few competitors touch, landing at the 89th percentile. That's days, sometimes weeks, of commuting without reaching for a charger. The quick-charge feature – five minutes for four hours – adds even more convenience. Connectivity via Bluetooth 5.2 and aptX Adaptive is rock-solid in our testing, and the 98th percentile ranking feels earned. Call quality, however, only hits the 85th percentile. The mic does a fine job in quiet rooms, but wind and background noise on city streets can make you sound a bit distant. For voice calls, you'll get acceptable clarity but nothing exceptional.

The Sony WH-1000XM6 is the most obvious rival. Sony's ANC is a hair better and the headphones feel lighter and roomier on the head, but their sound tuning is more bass-forward and less transparent than the Sennheiser. If you want a dead-quiet cabin on flights, the Sony or the Bose QuietComfort Ultra will serve you better. The Bose also has the most comfortable earcup design by a wide margin, but its sound signature is recessed in the mids, lacking the MOMENTUM 4's detail. Then there's the Bowers & Wilkins Px8 S2, which steps up the materials game with cast aluminum arms and Nappa leather, delivering a sound that's richer and more spacious than the Sennheiser, but it costs nearly double and its battery life is half as long.

The Technics EAH-A800 and JBL Live 770NC slip in below as more affordable alternatives. The Technics surprises with decent sound and strong ANC, but doesn't reach the audiophile clarity of the MOMENTUM 4. The JBL is a budget pick that can't compete on fidelity or battery. If you're deciding between these, the Sennheiser is your best bet for critical listening and marathon battery life, but be prepared to compromise a little on ANC supremacy and long-term comfort if you have bigger ears.

Pricing for the MOMENTUM 4 is all over the map. We've seen listings ranging from $196 to as high as $24,989 across vendors, likely because of refurbished units and odd marketplace listings. For a brand-new pair, you're typically looking at around $300 to $350 at major retailers like B&H or Amazon, which puts them right in the thick of the premium wireless headphone fight. At that price, the sheer sound quality and battery life give them an edge over the Sony WH-1000XM6 and Bose QC Ultra for audiophiles, though the Sony offers slightly stronger ANC and a more comfortable fit for most. If you can snag a refurb for under $200, it's an incredible deal. Just make sure you're buying from a reputable seller, because that $24,989 price tag is either a typo or a spaceship with headphone drivers.

If you're hunting for a pair of wireless noise-canceling headphones that put sound quality above all else, the Sennheiser MOMENTUM 4 should be near the top of your list. Sennheiser didn't chase the same design as the Sony WH-1000XM6 or Bose QuietComfort Ultra, but instead built these around large 42mm dynamic drivers, Hi-Res codec support, and an insane 60-hour battery life. In our database, the sound and connectivity scores land in the 98th percentile, making them one of the best-sounding wireless over-ear headphones we've tested in this price range.

The noise cancellation is adaptive and effective, though it's more about preserving music quality than creating complete silence. You get transparency mode, multipoint Bluetooth 5.2, and a solid onboard mic array that handles calls reasonably well. The headband and earcups fold flat for travel, and the whole thing weighs just 293g, so they're fairly light. But don't mistake them for rugged: the build is mostly plastic, and some owners find the earcups a bit snug.

Sennheiser pitches these at studio and music use, and our data backs that up with a 100/100 studio score and 96.3 for music. But the weakest area, calls at 73.7, hints that they're really meant for listening, not conference calls. Whether you're an audiophile upgrading from older wired cans or just someone who wants to hear every detail in TIDAL streams, the MOMENTUM 4 delivers where it counts most.

If you have larger ears or wear glasses for long stretches, you might want to pass on the MOMENTUM 4 because the earcup design and clamping force can get uncomfortable. Frequent fliers who demand true silence and wear headphones for hours should probably go for the Bose QuietComfort Ultra or Sony WH-1000XM6 instead. Likewise, if premium materials and a metal-reinforced build are must-haves, the Bowers & Wilkins Px8 S2 feels a lot more luxurious in hand, though it costs significantly more. And if you need top-notch call quality for work, look elsewhere; the mic is decent but not a standout.

So, should you buy the Sennheiser MOMENTUM 4? If sound quality and battery life are your top priorities, absolutely. These headphones deliver a detailed, natural listening experience that makes heavily produced tracks sparkle and acoustic recordings feel alive. The 60-hour battery means you can basically forget about charging for a couple of weeks. And while the ANC isn't the absolute best on the market, it's more than enough for most environments, especially when you're focused on the music.

Where we hesitate a bit is comfort and build. Our lab tests were stellar, but user sentiment in our database sits at only the 36th percentile. That gap tells a story: the earcups are small, the clamping force is stiff at first, and the plastic chassis doesn't scream premium. If you've got big ears or plan to wear these all day without breaks, you might end up annoyed. For everyone else, the MOMENTUM 4 is a sound-first powerhouse that outclasses its price in musical terms. Just make sure you try them on if possible, or buy from a shop with a good return policy.
