Ultrasonic Audio Jammer App

An ultrasonic audio jammer app may sound like an easy way to reduce unwanted voice recording, but there’s a catch: iPhones and Android phones cannot reliably replace dedicated ultrasonic hardware.

If you want to protect private conversations, a standalone microphone recording blocker is worth considering before spending time testing apps that may not work as expected. We offer affordably priced products, allowing you to try out this type of hardware without a significant financial investment.

Our ultrasonic anti-recording blocker range offers a practical alternative to app-based tools, with product details that help you check the specifications, operating method, and intended coverage before buying.

Important things

1.Please install the antenna before using the signal jammers

2.Most Portable cell phone jammers have dip switches on the side. After turning on the main power switch, activate the dip switch—the red or green light will indicate it's on. Each switch controls a specific signal (Refer to the frequency table on the packaging for details).

3.Avoid using the jammer while charging.
