Sennheiser Signature Sound

ACCENTUM Wireless features Sennheiser's in-house engineered 37mm dynamic transducer system, designed to reproduce music with powerful bass, natural vocals and detailed high frequencies.

With a frequency response extending from 10Hz to 22kHz, the headphones deliver balanced, immersive sound across a wide range of musical genres. Carefully tuned acoustics help preserve clarity and detail, whether enjoying music, podcasts or other entertainment.

Hybrid Active Noise Cancellation

Hybrid Active Noise Cancellation helps reduce distracting environmental sounds, allowing listeners to focus on music, entertainment and conversations.

Whether commuting, travelling or working in a busy environment, the ANC system helps create a more immersive listening experience by reducing unwanted background noise. Its combination of active noise cancellation and passive isolation helps maintain listening comfort in everyday environments.

Transparency Mode

Transparency Mode allows surrounding sounds to be heard without removing the headphones. This makes it convenient to listen for announcements, communicate with others or remain aware of the environment when needed.

Switching between noise cancellation and environmental awareness provides flexibility throughout the day.

Up to 50 Hours of Battery Life

ACCENTUM Wireless provides up to 50 hours of wireless music playback with active noise cancellation enabled. The long-lasting rechargeable battery makes the headphones ideal for extended travel, long workdays and everyday listening without frequent charging.

A full charge takes approximately three hours, while a quick 10-minute charge provides up to five hours of additional playback.

Personalized Sound with Smart Control Plus

The Sennheiser Smart Control Plus app allows users to customize their listening experience through a built-in five-band equalizer, selectable sound modes and Sound Zones.

Bass Boost provides a more powerful low-frequency presentation, while Podcast Mode is designed to improve the clarity of spoken content. Sound Personalization offers additional listening adjustments based on individual preferences, helping tailor audio reproduction to different music and entertainment applications.

Clear Calls with Beamforming Microphones

Two integrated MEMS microphones use beamforming technology to help capture speech while reducing unwanted background noise.

This microphone system supports hands-free calls and voice communication with compatible smartphones, computers and other Bluetooth-enabled devices, making ACCENTUM Wireless suitable for home offices, remote work and everyday communication.

Comfortable Over-Ear Design

ACCENTUM Wireless features a lightweight, ergonomic over-ear design engineered for comfortable extended listening sessions. Its circumaural earcups surround the ears, providing a comfortable fit and passive noise isolation that complements the Hybrid ANC system.

Weighing approximately 222 grams, the headphones are designed for everyday portability without sacrificing comfort or acoustic performance.

Bluetooth 5.2 Connectivity

Bluetooth 5.2 provides wireless connectivity with compatible smartphones, tablets, computers and other audio devices. Support for SBC, AAC, aptX and aptX HD codecs allows the headphones to adapt to different source devices and audio requirements.

Bluetooth Class 1 operation provides dependable wireless performance, while integrated controls make it convenient to manage music, calls and listening functions.
