Sennheiser ACCENTUM Over-Ear Wireless Headphones (Black)

When you need all-day comfort and top-notch sound, look to the black ACCENTUM Wireless Headphones from Sennheiser, which feature plush silicone earcups, custom TrueResponse transducers, and an incredibly long 50-hour operation on a single charge, letting you enjoy your music for the longest listening sessions without strain. 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.

Sennheiser ACCENTUM Wireless Reviews

Amazing!!!

Love my new headphone.

Bluetooth is a bad fit for my LG TV

Sennheiser headphones are terrific, but the bluetooth connection of the Accentum headphones paired with my LG TV is a C- fit. Just order the Sennheiser RS175RF headphones that connect to my TV with an optical cable, and I suspect they're going to work great.
