The Listen Technologies LK-1 is a transceiver designed for two-way mobile communications. It utilizes Listen Technologies’ proprietary encryption technology to ensure security, and provides easy-to-use, push-to-talk implementation in the field for simple coordination and communication among two or more collaborators in any scenario.

User controls such as volume up, volume down, talk, power/status, and pairing help you in tailoring the unit to your particular, moment-to-moment needs. Though the unit can be used with a Listen Technologies headset—or standard smartphone earbuds—the LK-1 comes with an LA-401 Universal Ear Speaker, as well as a lanyard (useful for on-the-go scenarios), and an LA-365 rechargeable lithium-ion battery. The LK-1 is fully compliant with ADA standards for assistive listening.
