Highlights & Key Technologies

Experience Sennheiser's Signature Sound
Discover exceptional sound with the 37mm dynamic transducer system that delivers brilliant dynamics, clarity, and musicality. Make the sound perfect for you using the built-in equalizer, presets, sound modes, and Sound Personalization feature available through the Sennheiser Smart Control app. The Sound Check function guides you step by step to create customized equalizer presets for optimal results, allowing you to tune your listening experience to your individual preferences.

Up to 50 Hours of Battery Life
Let nothing stand in the way of your listening pleasure. Keep on listening with up to 50-hour battery life when using Bluetooth with ANC activated. The fast charging capability provides a further 6 hours of listening in just 10 minutes. When you charge the headphones while they are switched off, the charging process is even faster. The Smart Control app displays the battery charge status, and voice prompts inform you of the remaining battery life when needed.

Active Noise Cancellation and Transparency Mode
Go from total immersion to situational awareness with ease. The Active Noise Cancellation automatically reduces ambient noise so you can stay immersed and hear every detail, even in noisy environments. Continuous and low-frequency noise, such as motor or fan noise, is particularly well suppressed. Wind Noise Reduction can be activated to minimize disturbing wind or movement noise. Need to hear an announcement on the train or have a quick conversation? Just activate the versatile Transparency Mode to hear outside sounds without removing your headphones. The Automatic Pause feature can be configured to mute audio playback when Transparency Mode is activated, or you can choose to have audio continue mixed with ambient sounds.

Premium Comfort and Design
Enjoy exceptional comfort with the ACCENTUM's lightweight design weighing approximately 222g. The cushioned earpads ensure long-lasting wearing comfort for extended listening sessions. The steplessly adjustable headband allows you to customize the fit for optimal sound quality and comfort. The ear pads completely surround your ears for optimal passive noise isolation and the best possible active noise cancellation performance.

Crystal-Clear Communication
Two MEMS omni-directional microphones with beamforming technology ensure high-quality voice pick-up for optimized calls and easier voice assistant access. The advanced microphone system ensures you can be heard perfectly during calls even in noisy environments. The Sidetone function allows your own voice to be audible in the headphones during phone calls for more comfortable communication, with adjustable intensity through the Smart Control app. During phone calls, Active Noise Cancellation is always activated to ensure the best possible speech intelligibility.

Intuitive Controls
The headphones feature an intuitive button control system on the right ear cup. Control music playback, adjust volume, manage phone calls, switch between ANC and Transparency Mode, and activate voice assistants all through simple button presses. The main button provides access to power, Bluetooth pairing, voice assistant activation, and ANC mode switching. Separate volume buttons allow precise control of playback levels.

Versatile Connectivity
Connect via Bluetooth 5.2 with support for aptX HD, AAC, and SBC codecs for high-resolution audio. If your audio source supports aptX HD or AAC, music is automatically played in high audio quality. USB-C connectivity allows direct audio streaming from Mac/PC/mobile devices, with the headphones serving as both audio output and input device. The headphones can save connection profiles of up to six Bluetooth devices and maintain active connections to two devices simultaneously. Multipoint connectivity allows you to seamlessly switch between devices for calls, music, and videos. Flight mode can be activated by deactivating Bluetooth while maintaining ANC functionality.

Smart Control App
The Sennheiser Smart Control app provides access to all functions and settings of the headphones. Customize sound using the built-in equalizer with predefined presets, sound modes such as bass boost, or create your own settings. The Sound Personalization feature assesses your listening preferences and adjusts the listening experience according to your taste. Adjust ANC settings including Wind Noise Reduction, configure Transparency Mode behavior including automatic pause, manage Bluetooth connections, customize the headphones' device name, adjust Sidetone intensity, delete the Bluetooth pairing list, reset to factory default settings, and install firmware updates. Voice prompts and sound signals can be activated or deactivated through app settings.
