The Case Ultra-06 emits ultrasonic interference that disrupts how microphones capture sound. It targets a wide range of devices, including smartphones, professional recorders, and hidden listening tools—even those inside metal casings. The result is distorted or unusable recordings, helping protect confidential information.

Use it in boardrooms, hotel rooms, vehicles, or temporary workspaces. Place it on a table or in the center of the area, activate it, and continue your conversation naturally. With silent operation and a professional briefcase design, it blends into business environments without drawing attention.

The built-in battery supports up to 8–9 hours of operation, with the option to connect to a 110–230V power source for extended use. Indicators show battery and charging status at a glance, while the included remote control lets you manage operation discreetly from a distance.

Unlike bulky or complex setups, this all-in-one system combines portability, controlled coverage, and simple operation. No noise, no visible signals, and no disruption to your meeting—just reliable privacy where it matters most.

Protect every critical conversation with reliable, discreet audio privacy.
