X37 Ultrasonic Recording Jammer with 37 Emitters and 5m Range

A conversation can disappear in seconds — but a recording can remain forever. The difficult part is that modern recording devices no longer need to look like traditional recorders. A small accessory, a hidden microphone, or an ordinary-looking electronic device may become a silent listener without attracting attention.

The ultrasonic recording jammer employs a distinct design approach. Equipped with 37 ultrasonic emitters and offering a 360° suppression angle, it ensures consistent coverage and creates a more balanced jamming field.

With an effective range of up to 5 meters, it generates a powerful ultrasonic interference environment that effectively compromises the performance of unauthorized recording devices.

For larger conference rooms or spaces requiring private recording, an ultrasonic audio jammer with 66 emitters —offering an interference range of up to 8 meters—is required; alternatively, you could purchase two X37 units.

Three switches are located on the back of the microphone jamming device, each controlling a specific group of ultrasonic emitters. When a group is activated, the corresponding indicator light illuminates immediately, enabling users to easily monitor the operational status of each section. The combination of multiple emitters and independent control switches offers operational flexibility.
