Sennheiser Unveils Momentum 5: More Mics, Stronger ANC, Replaceable Battery

Sennheiser has just dropped its newest flagship over‑ear headphones, the Momentum 5, and the tech‑savvy crowd is already buzzing. At first glance they look almost identical to the Momentum 4 that debuted a year ago, but look closer and you’ll spot a handful of thoughtful upgrades that feel like they were born from real‑world feedback.

First up, the microphone array. Where the previous model relied on a single inward‑facing mic for voice pickup, the Momentum 5 now sports three dedicated microphones – one outward‑facing to catch ambient sound, another positioned near the ear cup for wind‑noise reduction, and a third aimed straight at your mouth. The result? Calls that are noticeably clearer, even when you’re in a noisy café or a bustling office. It’s a small change on paper, but in practice it makes a big difference – you’ll finally hear yourself sound like you do in person.

Then there’s the active noise cancellation (ANC). Sennheiser says the new hybrid ANC system combines feed‑forward and feedback microphones with a refined digital algorithm. In plain English: the headphones do a better job at muting the rumble of a plane engine, the hiss of an air‑conditioner, or the chatter of a commuter train. In side‑by‑side tests, the Momentum 5 cut ambient noise roughly 15‑20 % more effectively than its predecessor, and the soundstage stayed surprisingly spacious – a tricky balance that many competitors still struggle to nail.

One of the most practical upgrades, though, is the replaceable battery. The Momentum 4 required a service centre visit once the internal cell finally gave up the ghost – not exactly convenient for anyone who lives on the go. The Momentum 5 solves that with a user‑replaceable Li‑Ion pack that slides out from the bottom of the right ear cup. It’s a quick swap that takes under a minute, and the battery life is still impressive: about 30 hours of playback with ANC on, or roughly 45 hours with it off.

On the connectivity front, the Momentum 5 sticks with Bluetooth 5.3, supporting SBC, AAC, aptX, and the high‑resolution aptX Adaptive codec. Pairing is still a breeze thanks to Sennheiser’s “Smart Pairing” feature, which remembers your devices and jumps straight into the connection. The headphones also keep the touch‑control panel on the right ear cup, but this time the gestures have been tweaked – a single tap still pauses or plays, a double‑tap skips tracks, and a three‑tap now invokes your voice assistant. A swipe forward or back adjusts the volume in smoother increments.

Audio quality? As expected from Sennheiser, the sound remains rich, detailed, and slightly warm. The 40 mm dynamic drivers have been fine‑tuned to pair nicely with the improved ANC, so you don’t get that hollow “canceled” feeling you sometimes hear with other brands. Bass is punchy without being overpowering, mids are clear and vocal‑friendly, and the highs sparkle without harshness. If you’re into high‑resolution streaming, the aptX Adaptive support will let you squeeze out every last nuance.

Design-wise, the Momentum 5 keeps the sleek, matte‑finished look that made the Momentum 4 such a style statement. The headband and ear‑cup padding still use the plush protein‑based leather, which feels soft yet breathable for long listening sessions. The only visual change is a subtle logo embossing on the inner side of each ear cup – hardly a giveaway, but a nice nod to the upgrade.

Pricing has been announced at €399 (around $429), which slots the Momentum 5 right in the premium segment, competing with the likes of the Sony WH‑1000XM5 and the Bose 700. Considering the extra microphones, the upgraded ANC, and the replaceable battery, many reviewers think the price is justified – especially for those who value call quality and want to avoid a costly service later.

All in all, the Momentum 5 feels like a genuine evolution rather than a gimmicky refresh. Sennheiser listened to what users complained about – call clarity, battery hassle, and occasional ANC quirks – and addressed them without sacrificing the brand’s hallmark sound signature. If you’re already a fan of Sennheiser’s audio philosophy, the Momentum 5 should feel like a natural next step.
