X21 Recording Jammer – 21 Ultrasonic Emitters with Remote & Voice Control

The X27 Audio Jammer is a compact, portable device that uses ultrasonic waves from 21 emitters to disrupt audio recording and eavesdropping devices. It effectively neutralizes smartphones, voice recorders, and hidden audio surveillance tools, ensuring private conversations remain confidential. Operating within a range of 2-6 meters, it provides reliable protection against unauthorized recordings.

The sound bugging device can be operated directly via onboard buttons, or remotely using a dedicated remote control or voice commands. This flexibility allows users to activate and adjust the jamming equipment effortlessly, ensuring smooth operation in various settings.

Additional Features & Applications：

Beyond audio jamming, the anti listening device emits ultrasonic waves that can act as a repellent for unwanted animals and insects, making it useful in both security and outdoor environments.

The voice jammer is completely safe for humans, producing no harmful effects on the body. When active, a faint noise may be audible within half a meter in very quiet rooms, but this does not interfere with normal conversation.

Adjustable Power for Different Environments

Ultrasonic recording blocker offers two power modes:

• Low-power mode – Ideal for small spaces like a car interior.
• High-power mode – Suitable for larger rooms, such as offices. By default, the second power level is activated after power is turned on.

Battery & Charging Requirements

• The built-in battery indicator automatically shuts down the device when power drops below 20%, ensuring optimal performance.
• The remote control only functions after manually activating the jamming device for at least 2 seconds. Once powered on, pressing the power button switches the device between standby and active modes.
• Charging Requirements: Always use the original 9V charger. Other voltages (5V or 12V) are incompatible and may damage the device. The X27 can function while charging, ensuring uninterrupted protection.
