LA451 Headset with earspeaker and boom microphone for LK-1

The LA-451 is a single-earpiece headset with boom microphone, designed specifically for use with the ListenTALK LK-1 transceiver. The single-ear design keeps one ear open to the surrounding environment — important on a factory floor, during a guided tour, or in any setting where situational awareness matters.

At just 27 g, it’s light enough to wear for a full shift or a long tour without discomfort. The boom microphone picks up voice clearly without needing to raise your voice, and the 104 cm cable gives comfortable reach from the LK-1 unit worn on a lanyard or belt clip.
