Mic-Lock USB-C Mini Single Ended Microphone Blocker Black - TSC Trusted Supply Chain

The Mic-Lock USB-C Mini TCS (Trusted Supply Chain) is a tiny, discreet adapter that helps you keep conversations private, wherever you work.
Because of its small size, it is easy to carry in your bag, pocket or case, so you can protect your audio on the go.

This USB-C Single-Ended Microphone Blocker works with devices that have a USB-C audio port, such as many modern laptops, tablets and phones.

How Mic-Lock protects your audio

Mic-Lock works by becoming your device's primary audio source. When plugged in, Mic-Lock will transmit the sound of an empty room to any government, app or individual who is listening in through your device's microphone.

Wat makes this Mic-Lock TCS unique

Inside the Mic-Lock is a real semiconductor that takes over the microphone function and actively sends silence. Many look-alike products are just dummy plugs that do not truly block the microphone. Mic-Lock is the only microphone blocker with a US patent for this approach, and is designed and made in the USA (Trusted Supply Chain). If you want a hardware-based solution you can rely on, this is the one to choos

The Mic-Lock is the only mic-blocker on the market that has a semiconductor inside the housing that actually takes over the microphone and transmits the sound of silence. All imitators are merely dummy plugs. Mic-Lock is the only microphone blocker that holds a US patent, and is the only one you can trust.
