Mic-Lock acts as your device’s primary audio source, feeding it an empty sound signal so that no real-world conversations can be recorded.

Mic-Lock is an audio blocker that prevents your device’s microphone from picking up sound by replacing it with silence. A Faraday bag is a signal blocker that shields your device from wireless signals (Wi-Fi, Bluetooth, GPS, RFID, etc.), preventing tracking, hacking and remote access.

If you are looking for a complete privacy solution, then yes. If you are worried about audio surveillance, Mic-Lock is essential. If you want to block EMF signals to prevent tracking, hacking or remote data extraction, a Faraday bag is the right choice.

No, many apps and spyware can secretly activate your mic without your knowledge. Mic-Lock physically blocks any microphone input, making unauthorized recordings impossible.

A Faraday bag blocks signals like WiFi, Bluetooth, GPS, and cell signals because it creates a shield that stops electromagnetic waves from passing through. However, it does not block sound because sound travels in a completely different way.

Electromagnetic waves (like radio signals) travel by means of alternating electric and magnetic fields, which Faraday bags block by redirecting them. Sound waves, on the other hand, are mechanical vibrations that move through the air and other materials. Since a Faraday bag is designed to block electromagnetic energy, not physical vibrations, it will not prevent sound from passing through.

Sound waves and electromagnetic waves (EMF) are completely different types of energy.

Sound waves are mechanical vibrations that travel through air, water or solid materials. Electromagnetic waves travel as electric and magnetic fields that do not need a physical medium.

A Faraday bag blocks electromagnetic waves by creating a conductive shield that reflects most of the energy away, while absorbing a small fraction that quickly dissipates as a miniscule amount heat.
