The Sennheiser Momentum 4 Wireless is the marathon runner of flagship headphones: a measured 56-plus hours per charge, five-star sound per TechRadar, and solid ANC that sits just behind Sony and Bose. If battery life and sound quality top your list, nothing else in the class comes close.
— THE VERDICT · JUDGEANY EDITORSWhy the Momentum 4 still matters
Sennheiser's MOMENTUM 4 Wireless arrived in 2022 with a spec no flagship rival has matched since: up to 60 hours of playback with ANC on, straight from Sennheiser's own spec sheet. Firmware updates since then — including one lifting aptX Adaptive to 24-bit/96 kHz — have kept the hardware current. This review gathers published specs, expert measurements, and aggregated owner impressions. We run no test lab; the scores are editorial judgments built on that evidence.
Battery life: the headline act
The numbers hold up. SoundGuys measured 56 hours and 21 minutes of continuous playback at 75 dB SPL with ANC on — more than 20 hours longer than the Sony WH-1000XM5 under identical test conditions, and close to Sennheiser's 60-hour claim. A 10-minute charge adds roughly 6 hours of listening, per the product listing. Owners treat charging as a rare event rather than a routine, which changes how you use a travel headphone.
Sound: flagship tuning without the fuss
The 42 mm dynamic drivers — 6 Hz to 22 kHz, 106 dB sensitivity — earned five-star sound from TechRadar, which called the presentation open, detailed, expansive, neutral, and crisp. SoundGuys' lab measurement lands very close to its headphone preference curve, deviating only with a modest sub-bass bump that the app's EQ tames easily. Android users get aptX Adaptive at 24-bit/96 kHz after a firmware update, per Digital Trends. The gap: no aptX Lossless and no LDAC, which Tom's Guide flags as a real downside for hi-res listeners.
Noise cancelling: strong, not the strongest
Adaptive ANC backed by four beamforming microphones cut high-pitched noise by roughly 75–95% and low-pitched noise by about 75% in SoundGuys' testing. Respectable numbers, but the same review is candid: the Momentum 4 hangs with the frontrunners while sitting decidedly behind Sony and Bose by a small margin. TechRadar still judged the ANC strong for the level. Wind-noise suppression helps calls; owners rate them as solid rather than standout.
Comfort and calls for the long haul
At 293 grams the Momentum 4 is no featherweight, yet owners consistently praise the fit — deep, soft earpads, a padded headband, and a low-friction hinge that adjusts without heavy clamping. It folds flat rather than inward, so the included case runs bulkier than some rivals'. Calls use the four beamforming mics with wind-noise suppression; Digital Trends called quality solid, and Tom's Guide found conversations satisfactory with a genuinely useful sidetone adjustment.
The caveats are worth knowing
The touch panel draws the most owner complaints — sensitivity that reads as inconsistent in daily use — and Tom's Guide reported flaky connectivity with the Smart Control app, though later updates claim better stability. The styling is plain where the Momentum 3 had character, the earpads can run warm per Tom's Guide, and there is no water-resistance rating. None of this dents the core proposition, but it keeps the Momentum 4 from feeling as polished as it sounds.
Who should buy it
Sound-first listeners and long-haul travelers who want to charge their headphones monthly, not weekly. If absolute best-in-class noise cancellation is the priority, Sony and Bose still measure ahead. For everyone else — commuters, frequent flyers, anyone who hates battery anxiety — the Momentum 4 remains the most practical flagship around.
