Audio T Verdict
The Sennheiser ACCENTUM Wireless get a great deal right without making things unnecessarily complicated. They combine Sennheiser's 37mm dynamic drivers with Hybrid Active Noise Cancellation, Transparency Mode, aptX HD Bluetooth and an exceptional 50-hour battery life.
They are light too, weighing just 222g, and use conventional physical buttons rather than relying on touch controls. Add a 5-band equaliser through Sennheiser's app, Bass Boost and Podcast modes, Bluetooth multipoint and the ability to stream audio digitally over USB-C from a compatible PC or Mac, and there is plenty here for everyday music, travel and working from home.
The ACCENTUM Plus add some worthwhile luxuries, but the standard ACCENTUM Wireless retain the core sound, long battery life and noise cancelling at a lower price. For many listeners, that makes them the sweet spot of the range.
Sennheiser ACCENTUM Wireless Headphones
The Sennheiser ACCENTUM Wireless are closed-back, around-ear Bluetooth headphones designed to combine everyday convenience with the company's established approach to headphone sound.
A pair of 37mm dynamic transducers provides the acoustic foundation, while Hybrid Active Noise Cancellation helps reduce external distractions. Transparency Mode lets surrounding sound back in when needed, and Bluetooth 5.2 includes support for aptX HD alongside AAC and SBC.
Battery life extends to an impressive 50 hours with Bluetooth and ANC operating, while a 10-minute fast charge can provide up to another five hours of music playback.

37mm Sennheiser Dynamic Drivers
The ACCENTUM Wireless use 37mm dynamic transducers designed and tuned by Sennheiser.
The drivers cover a specified frequency response from 10Hz to 22kHz, giving them the bandwidth required to reproduce deep bass, the midrange where much of the musical information sits and the upper frequencies responsible for detail and attack.
Sensitivity is specified at 106dB SPL at 1kHz, while total harmonic distortion is rated below 0.3% at 1kHz and 100dB SPL.
Sennheiser Sound
Sennheiser has designed the ACCENTUM Wireless to provide a full-bodied but balanced presentation suitable for a broad range of music.
The closed-back design reinforces low-frequency isolation while preventing as much sound escaping into the room as an open-backed headphone would.
That makes them suitable for both private listening at home and situations where you are sharing space with other people.
Closed-Back Around-Ear Design
The earcups surround the ears rather than resting directly on them.
This circumaural design helps spread pressure over a larger area and provides useful passive isolation before the electronic Active Noise Cancellation is even switched on.
Closed-back headphones are particularly useful for:
- Commuting
- Train journeys
- Air travel
- Office listening
- Working from home
- Shared living spaces
- Late-night listening
Hybrid Active Noise Cancellation
The ACCENTUM Wireless use Hybrid Active Noise Cancellation to reduce unwanted environmental sound.
Microphones positioned both inside and outside the earcups monitor external noise and allow the electronic system to generate a corresponding correction signal.
ANC is particularly effective with the relatively constant low-frequency noise produced by:
- Aircraft cabins
- Trains
- Road traffic
- Air conditioning
- Office ventilation
- General transport noise
Transparency Mode
Sometimes you need to hear the world rather than block it out.
Transparency Mode uses the headphone microphones to make external sound more audible without requiring you to remove the headphones.
This is useful when listening for an announcement, speaking briefly to somebody or simply wanting greater awareness of activity around you.
ANC or Transparency Mode?
Use Hybrid ANC when you want to reduce background noise and concentrate on your music. Switch to Transparency Mode when you need to hear announcements, conversations or other sounds around you without taking the headphones off.
Up to 50 Hours Battery Life
Battery life is one of the strongest practical features of the ACCENTUM Wireless.
Sennheiser specifies up to 50 hours of Bluetooth music playback with Active Noise Cancellation operating under its stated test conditions.
That gives most listeners enough capacity for several days of normal use or multiple long journeys without needing to find a charger.
Fast Charging
If you do run low, a complete recharge is not always necessary.
A 10-minute charge can provide up to five additional hours of music playback, making a quick top-up useful before leaving for work or heading out on a journey.
Approximately 3-Hour Full Charge
The built-in 800mAh lithium-ion battery takes approximately three hours to charge fully.
Charging is carried out through the USB-C socket using the supplied cable.
Bluetooth 5.2
The ACCENTUM Wireless use Bluetooth 5.2 Class 1 connectivity.
Supported Bluetooth profiles include A2DP, AVRCP, HFP, HSP and GATT, covering stereo music playback, remote control, calls and communication with compatible devices and apps.
aptX HD Bluetooth
For compatible transmitting devices, the ACCENTUM Wireless support Qualcomm aptX HD.
aptX HD provides an additional higher-quality Bluetooth option alongside conventional SBC and AAC transmission.
The codec actually used is determined by the capabilities and settings of the connected smartphone, computer, tablet or transmitter.
AAC and SBC
AAC and SBC provide broad compatibility with common Bluetooth equipment.
This means you do not need an aptX HD source to use the ACCENTUM Wireless; the headphones automatically use a mutually supported codec with the connected device.
Bluetooth Multipoint
The ACCENTUM Wireless can maintain two active Bluetooth connections at the same time.
You might, for example, have them connected to a laptop for music while remaining connected to your smartphone for an incoming call.
Multipoint is particularly useful for:
- Working from home
- Office systems
- Switching between laptop and phone
- Using separate work and personal devices
USB-C Audio From PC or Mac
The USB-C connection is not limited to charging.
Sennheiser also specifies the socket for calling and audio streaming when connected to a compatible PC or Mac.
This provides a useful wired digital alternative to Bluetooth when listening from a computer.
No Conventional 3.5mm Analogue Input
The standard ACCENTUM Wireless do not include the analogue audio socket fitted to the ACCENTUM Plus Wireless. Wired audio is available digitally through USB-C with a compatible PC or Mac, but there is no conventional 3.5mm analogue headphone input.
Physical Button Controls
Unlike the ACCENTUM Plus, which moves to a touch-sensitive control surface, the standard ACCENTUM Wireless use physical buttons.
Controls on the right earcup provide access to:
- Power
- Bluetooth pairing
- Volume
- Music playback
- Voice functions
- Calls
- Noise-control functions
Some listeners actively prefer physical controls because each press provides clear tactile feedback.
Sennheiser Smart Control
Connecting the ACCENTUM Wireless to Sennheiser's compatible control app opens access to additional sound settings and firmware updates.
The headphones can therefore be used perfectly well for straightforward Bluetooth listening while still providing deeper adjustment when you want it.
5-Band Equaliser
The app includes a 5-band equaliser for adjusting the tonal balance.
This allows you to tailor different areas of the frequency response rather than being limited entirely to the factory tuning.
You can use the EQ to adjust characteristics such as:
- Bass weight
- Lower-mid warmth
- Vocal presence
- Upper-mid clarity
- Treble balance
Bass Boost Mode
Bass Boost provides a quick option for listeners wanting a fuller and more prominent low-frequency presentation.
It can be activated without manually creating an equaliser curve.
Podcast Mode
Podcast mode places greater emphasis on speech intelligibility.
It can be useful not only for podcasts but also spoken-word programmes, interviews and other voice-focused content.
Sound Zones
Sennheiser's compatible app also supports Sound Zones, allowing preferred settings to be associated with different locations.
This can make it easier to move between different listening environments without repeatedly changing the same settings manually.
Beamforming Microphones
Two MEMS microphones are used for speech pickup during compatible phone and video calls.
The beamforming system is designed to focus more effectively on your voice while reducing distracting background sound.
The specified speech-microphone frequency response extends from 50Hz to 8kHz.
Lightweight 222g Design
The ACCENTUM Wireless weigh approximately 222g.
That is relatively light for full-sized wireless around-ear headphones containing a rechargeable battery and Active Noise Cancellation system.
Lower weight becomes increasingly important during long listening sessions because there is simply less mass being supported by your head and neck.
Cushioned Earpads
The around-ear cushions are designed to sit around the ears while the padded headband distributes pressure across the top of the head.
The headband is steplessly adjustable so the fit can be adapted to different head sizes.
Fold-Flat Earcups
The earcups rotate flat when the headphones are not in use.
This reduces the amount of depth they occupy in luggage or a bag, with folded-flat dimensions of approximately 165 x 195 x 48mm.
