Designed to facilitate two-way communications for four people, the LKS-1 Base-4 System from Listen Technologies bundles together six useful pieces of gear into one useful starter system. Included are four LK-1 Transceivers (with leader clips), one LA-452 headset, and one four-port USB charger for powering the units when they're not in use.

With this system, you'll have everything you need to enable communications between one team leader and up to three team members at any one time. This system is expandable, should you need to add more elements to it.

  • LK-1 ListenTALK Transceiver with Lanyard, Ear Speaker, and Battery

    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.

  • LA-452 On-Ear Headset with Boom Mic (Single-Ear)

    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.

  • 4-Port USB Wall Charger

    The 4-Port USB Wall Charger from LISTEN Technologies turns your wall outlet into a charging station, keeping your LISTEN iDSP products ready to go. It is a suitable accessory for personal use of iDSP products or for smaller venues. The charger's compact design makes it easy to store and does not block extra outlets on the wall. This charger is compatible with LISTEN iDSP receivers and supports input voltages of 100 to 240 VAC, 50 to 60 Hz. This model features four USB ports, and a small LED on the front of the charger illuminates when the charger is plugged into a live power socket. It comes with four USB-to-micro-USB cables.
