Sennheiser Momentum M4AEBT

The Sennheiser Momentum 4 Wireless serve up incredible, top-percentile sound and a 60-hour battery that’s the envy of the class. ANC is excellent, though not quite Sony-level, and call quality is solid. The real crux is comfort—the strong clamp and weight can wear you out fast, so they’re best for shorter, sound-focused sessions.

Sennheiser’s Momentum 4 Wireless (M4AEBT) are the kind of headphones you put on and immediately forget about your phone’s audio dongle drawer. They’re over-ear, closed-back cans that pack 42mm drivers, adaptive ANC, and a huge 60-hour battery into a fold-flat design. If you’ve been searching for premium wireless headphones that lean heavily into sound quality without making major sacrifices, these have been on a lot of shortlists. In our database, they sit at the very top for audio performance and noise cancellation, so it’s clear Sennheiser wasn’t messing around.

In our lab analysis, these hit the 98th percentile for sound quality—meaning they’re in the top 2% of all over-ear headphones we’ve tracked. The 42mm drivers deliver a wide soundstage and tight, textured bass that doesn’t muddy the mids. Treble is crisp without being harsh, and the default tuning feels instantly premium. The ANC also lands in the 98th percentile, so it’s among the absolute best right now. That silence isn’t quite Sony-level at killing human chatter, but it crushes plane rumble and office drone like a champ. Connectivity is another standout; Bluetooth 5.2 and aptX Adaptive kept our audio rock-solid across devices, and multipoint switching was snappy. Battery life comes in at an 89th percentile—60 hours is legitimately ridiculous, and the 5-minute quick charge for 4 hours of playback means you’ll rarely think about the charger. The mic quality is a strong 85th percentile, so calls sound clear even when a breeze picks up.

Pricing is wild. The official MSRP sits around $350, but we’ve seen a spread of nearly $40,000 across vendors. That’s right—someone out there is trying to sell these for the price of a used car. Your best bet is Best Buy, where we spotted them at $152 during recent dips. At that price, you’re getting audiophile sound and a 60-hour battery for less than half the cost of some rivals. Even at $300, the value is strong if sound is your priority. Just avoid the $40,000 listing; we have no idea what that includes, maybe a golden unicorn.

The Momentum 4’s two biggest rivals are the Sony WH-1000XM6 (or XM5, depending on what Sony has actually released) and the Bose QuietComfort Ultra. Sony takes the crown for sheer ANC effectiveness and all-day comfort—their lightweight design and softer clamp win for marathon listening. But the Sennheiser stomps on them for sound quality and battery life; 60 hours versus Sony’s 30 is a no-brainer. The Bose QuietComfort Ultra is similarly comfier and matches Sennheiser’s ANC quality, but again, the Momentum 4 pulls ahead in audio fidelity and battery endurance. Then there’s the Bowers & Wilkins Px7 S3, which feels more premium in the hand and has a similarly lush sound, but its battery is a fraction of the Sennheiser’s and the ANC is weaker. If you want a true all-rounder with top-tier ANC and comfort, the Sony or Bose are the safer picks. If you’re sound-first and can live with a tighter fit, the Momentum 4 is the clear winner.

If all-day comfort or absolute best ANC is your top priority, you’ll be happier with the Bose QuietComfort Ultra or Sony WH-1000XM6. The Sennheiser’s sound is phenomenal, but the tight grip and heavier build make them tough to wear for back-to-back meetings or cross-country flights without breaks. Travelers who need a folding design that compacts into a tiny pouch should also look elsewhere—these only fold flat, not into a tight ball. And if you mostly listen at low volumes, note that the Momentum 4 really shine at higher levels, so you might not get the full experience if you tend to keep things quiet.

Should you buy the Sennheiser Momentum 4 Wireless? If sound quality is your dealbreaker and you want ANC that is nearly class-leading, absolutely yes—especially if you can snag them at the Best Buy price of $152. The combination of sonic excellence, marathon battery life, and strong call performance makes them one of the best-sounding wireless headphones we’ve ever tested. But, and it’s a big but, the comfort issue is real. That clamp force and weight push them into “cannot wear all day” territory for a lot of people, and you should definitely try before you buy if you’re sensitive to pressure.
