Versatile wearing modes

The COSMUSIS BH654A over-ear headset switches between single-ear and dual-ear operation. Single-ear mode keeps drivers aware of traffic while taking calls, and dual-ear mode seals in stereo sound for music or focused work. Weighing 0.39 kilograms with an adjustable headband and memory-foam pads, it stays comfortable through long shifts.

Wireless freedom and quick power

Bluetooth connects to phones, tablets or laptops up to 10 meters away with no cable required. The battery delivers 50 hours of music playback or over 30 hours of talk time, and 200 hours of standby. A 15-minute charge adds useful runtime, while a full charge takes 50 minutes via the included USB cable.

Replaceable parts and call controls

Detachable ear pads let you swap sides for single or dual wear and replace worn cushions without tools. A multifunction button mutes the microphone instantly during calls, and the noise-cancelling boom mic reduces background sound to 117 decibels signal-to-noise ratio for clear voice pickup in cabins or offices.
