Mic-Lock TAA on a project basis: for organisations that make no compromises on audio privacy

Available only on special request

The Mic-Lock TAA versions are designed for organizations that need more than a standard privacy accessory. This version is only available on special request and on a project basis for three models: Mic-Lock 3.5 mm Gray TAA, Mic-Lock USB-C Mini Black TAA and Mic-Lock Lightning Mini TAA. The 3.5 mm Gray TAA is explicitly positioned by Hart 4 Technology as TAA-compliant, Made in the USA, and approved for government use; Hart4Technology also offers Mic-Lock product lines for 3.5 mm, USB-C, and Lightning.

Why this matters to you

If you work in defense, government, critical infrastructure, or an organization with strict supply chain requirements, you do not want a generic accessory with an unverified origin. You want a solution that aligns with your procurement policy, your compliance requirements, and your need for demonstrable audio privacy at the device level.

Mic-Lock is positioned by Hart 4 Technology and Mic-Lock as a plug-and-play microphone blocker that takes over the microphone function via a patented circuit, thereby blocking digital audio recordings. This makes it relevant for environments where even a single open audio channel poses too great a risk.

Why delivery is only on request

These TAA versions are not mass-produced items. They are handcrafted on a project basis, meaning availability and delivery times depend on capacity and planning.

This is exactly why you should not expect “next-day delivery.” Expect delivery on request, with a lead time of several weeks, precisely because these adapters are produced with care and in limited quantities. The advantage for you is clear: you receive not a bulk product, but a specialized solution for environments where reliability matters more than speed.

Why the Lightning Mini TAA takes longer

For the Mic-Lock Lightning Mini TAA , a longer lead time applies compared to the other TAA models. This version requires additional soldering work, making the production process more intensive and also explaining why the Lightning version is more expensive than the 3.5 mm Gray TAA and the USB-C Mini Black TAA.

For you, this mainly means clarity upfront. You understand why the delivery time is longer, why the price is higher, and why this version is particularly relevant if you want to include Lightning devices in a controlled TAA approach.

Protect confidential conversations with a Mic-Lock TAA solution tailored to your project. The Mic-Lock TAA series is intended for organizations that take audio privacy, supply chain integrity, and controlled origin seriously. That is why the TAA versions are only available on special request and on a project basis for the Mic-Lock 3.5 mm Gray TAA, Mic-Lock USB-C Mini Black TAA, and Mic-Lock Lightning Mini TAA.

Why you choose this:

• You want TAA-focused hardware for sensitive environments.
• You want a plug-and-play microphone blocker positioned as a patented solution.
• You prefer a lead time of several weeks over compromising on origin or project quality.

Important to know: Production is done manually and in limited quantities. As a result, delivery times are only available on request and may take several weeks. For the Lightning Mini TAA, this takes longer due to additional soldering work, which also explains the higher price.
