The combination of the over-ear design with the built-in Adaptive Hybrid Active Noise Canceling (ANC) ensures a noise-free listening experience regardless of your surroundings, and Transparency mode lets you stay aware of your environment without having to remove your headphones.

Dual noise-canceling microphones with beamforming support keep your calls crystal clear even in busy surroundings. Intuitive mechanical buttons allow you to control functions easily. You can engage a built-in 5-band EQ as well as several listening modes (Bass Boost, Podcast Mode, etc.) to cater your audio to your preferences. For even further customization, these Bluetooth 5.2 headphones can connect to the Sennheiser Smart Control app to adjust sound settings, zones, connections, and much more. These headphones include a USB-C charging cable.

Hear Every Detail

Angled TrueResponse transducers create a wider soundstage for a more immersive listening experience. Tailor your sound with Bass Boost and Podcast sound modes, or use the built-in 5-band equalizer and the Sennheiser Smart Control app. The ACCENTUM headphones support SBC, AAC, aptX, and aptX HD/Adaptive, ensuring the highest quality option is automatically selected for your device.

Make Long Listening Sessions Comfortable

ACCENTUM sports ultralong listening time with a whopping 50-hour battery life. When it's time to power them, recharging your headphones takes as much time as ordering a coffee to go. Just plug them in for 10 minutes and you get 5 hours of playtime.

The lightweight ergonomic design with an over-ear fit and soft-touch headband helps avoid listening fatigue. When you need to take your headphones to the next location, they fold flat for easy portability.

Listen Anywhere Without Distractions

Adaptive Hybrid ANC adjusts dynamically to changing noise levels to ensure a completely noise-free listening experience in difficult or busy environments. With Transparency mode, you can hear your surroundings at a touch without removing your headphones.
