SHIELD: Portable Speech Protector for Complete Eavesdropping Defense

The SHIELD Portable Speech Protector is a compact and powerful device engineered to safeguard your conversations from all types of wiretapping and eavesdropping.

Equipped with a built-in rechargeable battery that delivers up to 4 hours of continuous protection, it is the ideal companion for professionals who attend confidential meetings while on the move.

By generating ultrasonic noise to disrupt microphones — along with optional acoustic noise for added security — the SHIELD ensures that no unauthorized recordings can capture clear speech. This dual-layer protection provides a comprehensive defense against both traditional and advanced eavesdropping techniques.

Simple, Intuitive Operation

No complex setup required — just switch it on or off as needed.
Adjustable noise intensity allows you to fine-tune the protection level.
A blue backlight indicator confirms when the device is active.

Compact, reliable, and easy to use, the SHIELD Portable Speech Protector is your trusted solution for maintaining privacy wherever your work takes you.
