Mic-Lock TAA on a project basis: for organizations that make no concessions on audio privacy

Available by special request only

The Mic-Lock TAA versions are designed for organizations that need more than a standard privacy accessory. This version is only available by 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 Hart4Technology as TAA-compliant, Made in the USA and approved for government use; in addition, Hart4Technology supplies 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 without controlled origin. You want a solution that fits your procurement policy, your compliance requirements and your need for demonstrable audio privacy at device level.

Mic-Lock is positioned by Hart4Technology and Mic-Lock as a plug-and-play microphone blocker that takes over the microphone function via a patented circuit, so that digital audio recordings are blocked. This makes it relevant in environments where a single open audio channel is already too great a risk.

Why delivery is by request only

These TAA versions are not mass-produced items. They are hand-built on a project basis, which means availability and lead time depend on capacity and planning.

That is precisely why you should not count on “next-day delivery” here. Instead, expect delivery on request with a lead time of several weeks, exactly because these adapters are manufactured with care and in limited quantities. Your advantage is clear: you do not receive a bulk product, but a specialist solution for environments where reliability is more important than speed.

Why the Lightning Mini TAA takes longer

For the Mic-Lock Lightning Mini TAA there is a longer lead time than for the other TAA models. This version requires additional soldering work, which makes the production process more intensive and also explains 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 know why the lead time is longer, why the price is higher and why this version is especially interesting when you specifically want to include Lightning devices in a controlled TAA approach.

Protect confidential conversations with a Mic-Lock TAA solution that fits your project. The Mic-Lock TAA series is designed for organizations that take audio privacy, supply chain integrity and controlled origin seriously. That is why the TAA versions are only available by 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 microphone blocker that works plug-and-play and is positioned as a patented solution.
• You would rather accept a lead time of several weeks than make concessions on origin or project quality.

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