Audio T Verdict
The Sennheiser ACCENTUM Plus Wireless take the already capable ACCENTUM formula and add the features that make the biggest difference when headphones become part of everyday life. Adaptive Hybrid Active Noise Cancellation automatically responds to changing surroundings, while Sound Personalization, touch controls, Smart Pause and automatic anti-wind mode make them considerably more sophisticated than the standard ACCENTUM Wireless.
The fundamentals are strong too. Sennheiser's angled 37mm dynamic drivers deliver a spacious presentation, Bluetooth includes aptX Adaptive support, and the battery lasts for up to an impressive 50 hours even with ANC operating. A 10-minute charge can provide another five hours of listening.
For commuting, travelling, working from home or simply listening without disturbing anybody else, the ACCENTUM Plus strike an excellent balance between sound quality, useful technology, comfort and battery life.

37mm Dynamic Drivers
Sennheiser uses its own 37mm dynamic transducer system within the ACCENTUM Plus.
The drivers cover a specified frequency range of 10Hz to 22kHz and have been positioned at an angle within the earcups rather than firing directly towards the ears.
This arrangement is intended to create a wider and more enveloping presentation, helping music feel less confined to the physical dimensions of the headphones.
Angled Transducer Design
The angle of a headphone driver affects how sound reaches the outer ear before entering the ear canal.
By angling the ACCENTUM Plus drivers, Sennheiser aims to create a more spacious sense of presentation than simply positioning the transducer directly beside the ear.
Closed-Back Around-Ear Design
The earcups surround the ears rather than sitting directly on them, while their closed-back construction provides useful passive separation from the surrounding environment.
That makes the ACCENTUM Plus particularly suitable for:
- Commuting
- Train journeys
- Air travel
- Office listening
- Working from home
- Listening in shared rooms
- General portable use
Adaptive Hybrid Active Noise Cancellation
The ACCENTUM Plus go beyond fixed-level noise cancellation by using Adaptive Hybrid ANC.
The system responds dynamically to changing background noise, adjusting its operation as the environment around you changes.
This is particularly useful during journeys where the amount and character of background sound can vary considerably between a quiet platform, busy station, moving train or aircraft cabin.
Why Adaptive ANC?
Active Noise Cancellation works by using microphones and processing to reduce unwanted environmental sound reaching the listener.
An adaptive system can continually respond to those conditions rather than relying on one fixed level of cancellation.
The result is a more automatic listening experience where the headphones do more of the work for you.
Transparency Mode
There are times when blocking out the outside world is exactly what you want, and others when it is important to hear it again quickly.
Transparency Mode allows more external sound through without requiring you to remove the headphones.
This can be useful when:
- Listening for station announcements
- Speaking briefly to somebody
- Walking in busy surroundings
- Waiting at an airport gate
- Remaining aware of activity around the office
ANC or Transparency Mode?
Use Adaptive ANC when you want to reduce distractions and concentrate on your music, podcast or film. Switch to Transparency Mode when you need greater awareness of voices, announcements or other sounds around you.
Sound Personalization
The ACCENTUM Plus include Sennheiser's Sound Personalization system, developed with the Fraunhofer Institute.
Rather than simply selecting from a small collection of preset tonal balances, the system guides you through a listening process and uses your preferences to create a personalised sound profile.
This allows the headphones to be adapted more closely to the way you hear and the presentation you prefer.
5-Band Equaliser
If you would rather make your own adjustments, the Sennheiser Smart Control app includes a 5-band equaliser.
This gives more direct control over the tonal balance, while additional sound modes provide convenient alternatives when you do not want to build your own EQ setting from scratch.
Sound Modes
The app provides additional listening options alongside Sound Personalization and the manual equaliser.
This means you can keep things simple with an existing sound mode or spend more time tailoring the presentation to your own taste.
Bluetooth 5.2
Wireless connectivity is handled by Bluetooth 5.2 Class 1.
The ACCENTUM Plus support A2DP, AVRCP, HFP, HSP and GATT Bluetooth profiles, covering music playback, remote control and compatible voice-call functions.
aptX Adaptive
Supported Bluetooth audio codecs include SBC, AAC, aptX and aptX Adaptive.
aptX Adaptive is designed to adjust transmission according to wireless conditions and the content being played when used with a compatible transmitting device.
Codec selection will depend on the capabilities of the connected phone, tablet, computer or Bluetooth transmitter.
SBC and AAC Compatibility
SBC and AAC support helps maintain broad compatibility with common Bluetooth equipment, including smartphones, tablets and computers.
You do not need an aptX-compatible source simply to use the headphones wirelessly.
Touch Controls
The outer earcup incorporates touch-sensitive controls for common music and call functions.
Sennheiser's interface allows you to:
- Tap to play or pause
- Swipe to change tracks
- Adjust volume
- Answer calls
- End calls
- Access everyday headphone functions without reaching for your phone
Smart Pause
Smart Pause automatically responds when the headphones are removed.
Playback can pause when you take them off, helping prevent you from missing part of a track, podcast or programme while the headphones are away from your ears.
Automatic Anti-Wind Mode
Wind can create unwanted low-frequency noise around the microphones used by noise-cancelling headphones.
The ACCENTUM Plus incorporate an automatic anti-wind mode designed to respond when those conditions are detected.
This is particularly useful when using the headphones outdoors.
Beamforming Microphones
The ACCENTUM Plus use MEMS microphones with beamforming for voice pickup and noise reduction.
The microphone system is designed to focus more effectively on your voice during compatible calls while reducing distracting background noise.
The specified microphone frequency response is 50Hz to 8kHz.
Up to 50 Hours Battery Life
One of the ACCENTUM Plus's strongest practical features is battery life.
Sennheiser specifies up to 50 hours of music playback over Bluetooth with ANC operating, based on an iPhone at a medium listening level.
That provides enough capacity for several days of typical listening or multiple long journeys between charges.
10-Minute Fast Charge
If the battery is running low, you do not necessarily need to wait for a complete recharge.
A 10-minute charge can provide up to five hours of additional music playback.
This is particularly useful before leaving for work, catching a train or boarding a flight.
Approximately 3.5-Hour Full Charge
A complete recharge takes approximately 3.5 hours under Sennheiser's specified conditions.
Charging is carried out through the USB-C socket using the supplied cable.
800mAh Rechargeable Battery
The headphones contain a built-in 800mAh lithium-ion rechargeable battery.
The long operating time means regular users should spend considerably less time thinking about battery management than with many smaller wireless headphones.
227g Lightweight Design
Despite their around-ear construction, battery and noise-cancelling electronics, the ACCENTUM Plus weigh approximately 227g.
Keeping weight under control is particularly valuable for headphones designed to be worn during long journeys or extended working sessions.
Soft Cushioned Earcups
Sennheiser combines the lightweight structure with cushioned earcups and a soft-touch headband interior.
The aim is to spread contact around the ears and across the head rather than concentrating pressure in one small area.
Fold-Flat Design
The earcups can rotate so the headphones sit flatter when they are not being worn.
Sennheiser specifies approximate folded-flat dimensions of 165 x 195 x 48mm.
A dedicated carry case is supplied to protect the headphones while travelling or when stored in a bag.
Wired Listening Option
An auxiliary audio cable is included alongside the USB-C charging cable.
This provides a useful alternative when connecting to equipment with a conventional headphone output or where Bluetooth is unavailable.

Useful for Commuting
Adaptive ANC can help reduce the steady background noise associated with trains and other public transport, while Transparency Mode makes it easier to hear announcements when required.
The long battery life also means daily commuters should not need to charge the headphones every evening.
Useful for Long-Distance Travel
Up to 50 hours of listening with ANC makes the ACCENTUM Plus particularly well suited to extended journeys.
The combination of noise cancellation, closed-back earcups, fast charging and a supplied carry case covers many of the practical requirements of travel headphones.
Useful for Working From Home
The closed-back design helps keep distractions under control, while beamforming microphones support compatible voice calls.
Transparency Mode also makes it easier to reconnect with your surroundings without continually removing the headphones.
Useful in the Office
Adaptive ANC can help create a more focused listening environment in a busy workplace.
When somebody needs your attention, Transparency Mode or simply removing the headphones with Smart Pause makes switching between private listening and conversation straightforward.
