A closed-back wireless noise-canceller with one 37 mm driver per side, a rated 50-hour battery (SoundGuys measured 53 h 15 min, COMPUTER BILD over 49 h) and a full-featured app. Most sources agree on three things. The battery is class-leading. The noise cancelling is good for the price but behind Sony and Bose. And the tuning is broadly Sennheiser-neutral. Two lab rigs show a sub-bass shelf about 6 dB over target, and a third the same shape, with a near-target midrange and treble and less bass than the Momentum 4. How reviewers hear that is the main split. Most call the bass weighty and controlled, but some call it soft or tubby, and two call it light. Most hear clear, detailed treble, but a group hears a sharp or sibilant peak, and one hears it as polite. Comfort also splits. The headphones are light (227 g) and the pads are soft, but the cups are small and the clamp is firm, and several reviewers and owners with larger heads or ears gave up on them. Build is the weakest area. Some reviewers call the plastic well finished, while others call it cheap, and owners report pleather pads tearing, touch controls and wear detection that stop working, and left-earcup faults. At its current price most sources call it good value, unless a discounted Momentum 4 is within reach.
About this product
The ACCENTUM Plus Wireless, launched in February 2024 at $229.95 / £199.99 / €229.99 between the cheaper ACCENTUM Wireless and the MOMENTUM 4. It keeps the base model's 37 mm driver and 50-hour battery and adds adaptive noise cancelling, touch controls, wear detection, aptX Adaptive, a wired input and a carry case. Not the base ACCENTUM Wireless or the ACCENTUM Wireless SE.
Sennheiser's ACCENTUM Plus arrived in February 2024 to fill the gap between the budget ACCENTUM Wireless and the MOMENTUM 4. It uses the cheaper model's 37 mm driver and plain plastic body, adds most of the Momentum's conveniences (adaptive noise cancelling, a touch panel, wear detection, a wired input, a case), and keeps the 50-hour battery that is the family's headline feature.
It launched at $229.95 and now sells for about $130, and the Momentum 4 often sells for not much more. Reviewers mostly rate it as a good, sensible mid-price noise-canceller. What they disagree on is the sound, which some describe as weighty and others as tubby, light, sharp or polite, and the fit, which is light but snug.
