In short
Get the Sennheiser Accentum Wireless if you want 50 hours of noise-cancelled listening and aptX HD for less than the Accentum Plus: $179.95 at launch. It folds flat, weighs 222 g, and its USB-C cable doubles as a wired audio connection. Skip it if you want a case or a 3.5 mm cable in the box; the Accentum Plus includes both, plus aptX Adaptive.
Who it is for
- Travelers who want long battery for less. Sennheiser rates the Accentum Wireless for up to 50 hours with noise cancelling on, the same as the Accentum Plus, at a lower launch price.
- Listeners whose phone supports aptX or aptX HD. The Accentum Wireless handles both, along with SBC and AAC.
- Laptop and desktop listeners. The Accentum Wireless's USB-C cable doubles as a wired USB audio connection for music and calls.
Who should skip it
- Anyone who wants a case or a 3.5 mm cable in the box. The Accentum Plus includes both, along with aptX Adaptive.
- Listeners who want aptX Lossless or a battery they can replace. Those are Momentum 5 features.
What sets it apart
- Up to 50 hours of music with noise cancelling on (Sennheiser's test: iPhone, medium volume); 10 minutes of charging gives up to 5 hours.
- Plays aptX and aptX HD as well as SBC and AAC.
- Folds flat and weighs 222 g, 5 g less than the Accentum Plus.
- The USB-C cable doubles as a class-compliant USB audio connection.
- Hybrid noise cancelling with a Transparency Mode.
Caveats
- Sennheiser doesn't list multipoint for the Accentum Wireless, so don't count on two connections at once.
- Sennheiser lists no water or sweat resistance for it.

Accentum Wireless or Accentum Plus?
The Accentum Plus sits above the Accentum Wireless in Sennheiser’s range, and the two share a 50-hour battery rating, so choosing between them comes down to what’s in the box and a couple of features:
| Spec | Accentum Wireless | Accentum Plus |
|---|---|---|
| Noise cancelling | Hybrid | Adaptive |
| Codecs | SBC, AAC, aptX, aptX HD | Adds aptX Adaptive |
| Battery, noise cancelling on | Up to 50 hours | Up to 50 hours |
| Weight | 222 g | 227 g |
| In the box | USB-C cable, quick guide | Adds a zip case and a 3.5 mm cable |
If you’ll plug into a headphone jack, or you want something to protect the headphones in a bag, the Plus earns its higher price. If you mostly listen over Bluetooth or USB-C, the Accentum Wireless gives you the same battery rating for less.
Battery and charging
| Mode | Accentum Wireless |
|---|---|
| Music, noise cancelling on | Up to 50 hours |
| Quick charge | 10 minutes for up to 5 hours |
| Full charge | About 3 hours |
| Battery | 800 mAh, built in |
Sennheiser measured the 50 hours on an iPhone at medium volume with noise cancelling on.
Noise cancelling and calls
The Accentum Wireless uses hybrid noise cancelling, and Transparency Mode lets you hear your surroundings without taking the headphones off. Two beamforming MEMS microphones pick up your voice on calls.
Codecs and wired listening
Over Bluetooth 5.2 (class 1) it supports SBC, AAC, aptX and aptX HD, and aptX HD needs a phone or player that supports it. There’s no 3.5 mm cable in the box, but the USB-C cable doubles as a class-compliant USB audio connection, so a computer can use the Accentum Wireless as a wired headset for music and calls.
Sound and the app
Sennheiser tuned the 37 mm driver for bass and clarity and optimized the acoustics for broad noise cancelling. The app is Smart Control for iOS and Android, though some of Sennheiser’s US marketing calls it Smart Control Plus and mentions Sound Personalization.
Folding, weight and colors
The Accentum Wireless weighs 222 g (0.222 kg) and folds flat for travel. Black shipped from 4 October 2023, after pre-orders opened on 26 September 2023, and White with sandstone accents followed in late November 2023.
Price
The Accentum Wireless launched at $179.95, and Sennheiser’s US store listed it at $189.95 on 19 September 2026. Compare Sennheiser’s store with other retailers before you buy.
