Ultrasonic Recording Jammer with 270° Coverage and Adjustable Power Control 66W

At first glance, the AUP-3 looks like an ordinary desktop speaker. There are no obvious antennas or unusual structures, which makes it easy to blend into everyday environments.

The interesting part is hidden inside: this speaker-style recording jammer uses high-power ultrasonic output to create a protective area while maintaining a simple and familiar appearance.

The biggest difference comes from its 270-degree ultrasonic coverage. Instead of focusing sound protection in only one direction, the ultrasonic anti recording jammer creates a wider protection field with an effective range of 2 to 12 meters, making it suitable for desks, meeting areas, offices, and other indoor spaces where voice privacy matters.

Another practical feature is the continuously adjustable power control. Unlike devices with fixed step levels, the anti listening device allows users to fine-tune the output through a smooth adjustment knob. Given the varying acoustic conditions of different venues, this control method can greatly simplify daily operations.

Power flexibility is another highlight. The built-in 12V rechargeable lithium battery provides around 4–6 hours of operation after a full charge, with a charging time of approximately 3.5 hours. The 60W ultrasonic output system is housed inside a durable high-strength polymer shell, balancing portability with long-term reliability.

For added convenience, the speech blocker comes with a wireless remote control and dual switching options. The remote control works within a range of 1–30 meters, allowing users to operate the device without needing to approach it directly.
