Product Overview

The Williams AV MIC 158 is a dual-muff headset microphone with a single 3.5 mm TRRS plug, designed for the Digi-Wave DLT 400 transceiver. It pairs a unidirectional electret boom microphone with 50 mm dynamic headphone drivers, giving interpreters, tour guides, and intercom users clear two-way audio in one comfortable headset. With both ears covered, it suits Digi-Wave deployments where users need to focus on program or interpretation audio while speaking.

Product Description

The MIC 158 is the standard dual-muff talker headset for Digi-Wave 400 Series systems. Its single TRRS connection carries microphone and headphone signals through the DLT 400’s headset jack, eliminating the adapters legacy dual-plug headsets require. That makes it a clean specification choice for interpretation kits, guided tour packages, and staff intercom systems built on the Digi-Wave platform.

The unidirectional electret element delivers a 100 Hz 12 kHz response with better than 50 dB signal-to-noise ratio, keeping the transmitted voice clear while rejecting off-axis room noise. On the listening side, 50 mm dynamic drivers reproduce 10 Hz 20 kHz at 32 impedance with up to 96 dB maximum SPL, comfortable headroom for monitoring floor feeds or interpretation channels in active venues. The 42-inch cord reaches belt-worn or tabletop transceivers, and field-replaceable consumables the WND 058 windscreen and EAR 058 earpads keep rental and institutional inventories serviceable over time.

Where only one ear should be covered, such as docent tours where guides must stay aware of their group, specify the single-muff MIC 157. For high-noise industrial routes, step up to the MIC 168 or hard-hat MIC 188. Browse Digi-Wave transceivers and accessories in our Williams AV collection.
