XBT Heavy-Duty Bluetooth Headset with SENS Situational Awareness

The Motorola RLN6491B XBT Heavy-Duty Wireless Headset combines Bluetooth radio communication, hearing protection, and situational awareness in a rugged over-the-head design. Its dual-ear configuration provides a 25 dB Noise Reduction Rating to help protect users working around harmful industrial noise.

Motorola’s patented SENS technology combines speech enhancement with advanced noise suppression. It reduces damaging equipment noise while allowing users to remain aware of important surrounding sounds such as nearby speech, alarms, alerts, and approaching vehicles.

An integrated boom microphone supports clear voice transmission, while controls located on the ear cup provide convenient push-to-talk and audio operation. Wireless connectivity eliminates the cable between the headset and compatible radio, providing greater freedom of movement in demanding work environments.

The rechargeable lithium-polymer battery provides up to 22 hours of typical operation and requires approximately seven hours for a complete charge. The headset carries an IP54 rating for protection against dust and splashing water.
