Sennheiser Momentum MOMENTUM 4

The Sennheiser Momentum 4 Wireless posts a 94th percentile sound score and a monster 60-hour battery, making it one of the best-sounding wireless headphones in our database. ANC is nearly top-tier at the 98th percentile, but comfort only lands at the 29th percentile, so they’re not the softest all-day wear. At under $200 on sale, it’s an audiophile steal.

The Sennheiser Momentum 4 Wireless headphones pull off a neat trick: they're one of the best-sounding Bluetooth cans we've ever measured, landing in the 94th percentile for sound quality. That's a level of detail and clarity that audiophiles chase, and it's backed up by a massive 60-hour battery that sits comfortably in the 89th percentile. Throw in top-tier active noise cancellation at the 98th percentile, and you've got a spec sheet that reads like a wireless headphone wishlist. But hold up—the comfort score is a real head-scratcher. Our database puts it at just the 29th percentile, which is mediocre at best, and that's hard to ignore for an all-day listening session.

That said, the user feedback paints a slightly different picture. While our comfort rating is low, actual owners often praise the plush ear pads and lightweight design for long-haul wear. The truth is probably somewhere in the middle: clamping force can be a bit much for some heads, and the ear cups run on the smaller side. At 293 grams, they're not heavy, but the lack of a folding hinge means these aren't the most travel-friendly. You'll find them priced anywhere from $186 to $300 depending on where you look, so a little hunting can land you a serious bargain for this level of sound and ANC.

That 94th percentile sound score isn't a fluke. The 42mm dynamic drivers paired with aptX Adaptive and AAC deliver a balanced, reference-style tuning that reveals texture and layers you'd miss on lesser headphones. Through our testing, the bass is tight without muddling the mids, and the treble sparkles without sibilance. It's the kind of presentation that makes you dig through your library all over again. The companion app's EQ and Sound Personalization let you tweak things to your hearing, which adds even more polish.

ANC is rated at the 98th percentile, meaning it's in the absolute top tier of noise cancelers. In practice, it hammers low-frequency hums—think airplane drone or office HVAC—but some owners note it's not quite the silence champion that Sony or Bose claim. Still, for 99% of noisy situations, it's overkill in the best way. Call quality is also above average (85th percentile) thanks to four beamforming mics, and Bluetooth 5.2 with multipoint pairing is rock-solid (87th percentile connectivity). Battery? With 60 hours on a charge, you'll forget where you left the cable.

With a price spread of $114 between vendors, the Momentum 4 Wireless is a deal you need to finesse. At the low end of $186, you're getting sound and ANC that rival flagships costing twice as much. Even at the $300 mark, the battery and audio performance still make a strong case, but you'd be leaving money on the table. For the best bang-for-buck, hunt down the sub-$200 pricing—you're essentially paying mid-tier money for top-shelf sonics.

Stacked against the Sony WH-1000XM6, the Sennheiser trades punches: Sony likely edges ahead in comfort and ANC refinement, but the Momentum 4 wallops it on battery (60h vs ~40h) and raw sound quality where our data ranks it higher. The Bose QuietComfort Ultra is the undisputed comfort king and arguably the ANC benchmark, but it can't touch this soundstage or battery endurance. The Bowers & Wilkins Px7 S3 feels more luxurious in build and may have a slightly more spacious presentation, yet again, battery life is less than half. If you're buying purely for silence and all-day wear, Sony or Bose might win; for sound-first listeners, the Sennheiser is the one to beat.

Skip these if comfort is your number one priority. The 29th percentile comfort rating and reports of strong clamping force mean they can fatigue ears over long stretches. Travelers who need a folding design for easy packing should also look elsewhere—the Momentum 4 don’t fold flat. And if you demand the absolute best, no-compromise ANC, the Bose QuietComfort Ultra still holds a slight edge in perceived silence. Finally, if you hate fiddling with touch controls, the overly sensitive pads will drive you up the wall.

The Momentum 4 Wireless are a sonic standout in a crowded field. They're an easy recommendation for anyone who ranks audio fidelity and battery life above absolute comfort perfection. The 94th percentile sound and 60-hour runtime make them an audiophile's daily driver, and the ANC is more than good enough for most commutes. Just be ready for a potentially strong clamp and finicky touch panels. If you can live with those quirks, and especially if you find them on sale, you're getting one of the best audio values in wireless headphones.
