The Listen Technologies LA-453 is an over-the-head, on-ear headset with a dual-eared construction. It’s designed to be used with two-way communications devices such as the Listen
TALK 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 3.2 oz, the LA-453's dual-eared construction promotes audio clarity even in loud scenarios,
allowing you to focus on the voices coming through the headset.
