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 Listen Technologies LA-452 is an over-the-head, on-ear headset with a single-eared construction. It’s designed to be used with two-way communications devices such as the ListenTALK LK-1 Transceiver. The over-the-head construction provides both comfort and a secure fit, while its built-in boom mic facilitates hands-free communication. With a unidirectional polar pattern and noise-reduction technology, the on-board microphone offers clear amplification of your voice—and your voice alone. A 3.5mm TRRS connection point is compatible with many two-way systems. Lightweight at 2.2 oz, the LA-452's single-eared construction promotes audio clarity in its signal path without blocking outside sounds, thus allowing you to hear both your surroundings and the headphones.

The Listen Technologies LA-481 Docking Station Case 16 provides all the charging possibilities of the LA-480, but also offers a portable, secure carrying case. The docking station itself boasts charging slots for up to 16 ListenTALK transceivers and headsets. Each slot utilizes a tension lock to facilitate a secure connection while your devices are charging. Furthermore, each empty slot can double as a placeholder for an ID card, ticket, or whatever stand-in you choose when lending out a transceiver/headset; this helps keep your array of ListenTALK technologies organized.

In addition to its 16 individuated charging slots, the case also sports two large pockets for storing earphones in a tangle-free fashion, as well as other apposite items. Durable latches secure the case, while an included shoulder strap allows you to transport it in a convenient manner.
