XBT Behind-the-Neck Bluetooth Headset with SENS Situational Awareness

The Motorola RLN6490B XBT Heavy-Duty Wireless Headset combines Bluetooth radio communication, hearing protection, and situational awareness in a rugged behind-the-neck design. Its dual-ear configuration provides a 23 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.

The behind-the-neck wearing style leaves the top of the wearer’s head unobstructed, making the headset suitable for use with many hard hats, helmets, and other head-worn protective equipment. An integrated boom microphone and ear-cup PTT provide convenient two-way radio operation without a cable connecting the headset to the radio.

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.
