Mic-Lock 3.5mm Single Ended Microphone Blocker Gray - TSC Trusted Supply Chain - gray

Mic-Lock 3.5 mm TCS Microphone Blocker

The Mic-Lock 3.5 mm TCS is a hardware-based microphone blocker designed for government agencies, critical infrastructure operators and other organizations that require stronger protection against covert audio surveillance. Compatible with devices that feature a 3.5 mm audio port, it provides a simple physical control for environments where privacy and operational security matter most.

Why choose Mic-Lock?

When inserted, Mic-Lock becomes the device’s primary audio source and transmits the sound of an empty room instead of live conversations. This helps reduce the risk of unauthorized listening through compromised apps, malware or other attempts to access the microphone.

Built for high-security environments

Unlike standard dummy plugs, Mic-Lock uses patented technology with an integrated semiconductor inside the housing to take over the microphone function. This makes it a practical option for meeting rooms, secure offices, remote work locations and other sensitive environments where organizations want an additional layer of audio privacy.
