Sennheiser Accentum Wireless Headphones

The Sennheiser Accentum Wireless ACAEBT Black headphones are on-ear models built for wireless listening. They use a 37 mm dynamic driver and hybrid active noise cancellation to reduce ambient sound. A 3.5 mm connector is also provided for wired use when needed.

Commuter and office listeners

The 50 hour battery life suits long journeys or full work days without recharging. A ten minute charge adds roughly five hours of playback for quick top-ups. Buyers who need over-ear cups or a lighter clamp force should consider a different design.

Hybrid ANC with 50 hour runtime

Hybrid active noise cancellation combines feed-forward and feedback microphones to suppress low and mid-range noise. Transparency mode lets outside sound pass through when awareness is required. The 50 hour figure applies to Bluetooth playback with ANC active.
