Why don’t Microphone Blockers work?
To clarify why a microphone blocker doesn’t work, it is first necessary to understand the logic behind so-called “mic blockers” (also called “mic locks”).
Microphone blockers are inserted into your device’s audio jack. Once plugged in, your device is tricked into thinking that there is an incoming audio signal (i.e. sounds or noises). Because the microphone blocker is not actually sending a signal, there should be silence on the receiving side of things (in this case a hacker). Your privacy is now secured and locked up, right?
Unfortunately, your laptop, smartphone, iPhone or Macbook has other hidden microphones than can be compromised. A hacker has software control and can choose which microphone they want to use. If one is blocked, they can use another. This is why mic blockers do not work. Using a mic blocker to secure your audio privacy is like locking your front door but leaving open a window. We don’t want to sell a solution that is ineffective against hackers eavesdropping on your device.
Instead, provide your employees, clients and professional connections with real digital privacy solutions. Check out our custom privacy products that can be fully printed with your logo.
