MQ-79: The Professional Covert Voice Recording Pen

The Esonic MQ-79 is a professional-grade surveillance asset disguised as a high-end executive writing instrument. Designed for high-stakes environments where carrying a dedicated recording device is a security risk, it offers the ultimate “plain sight” camouflage for legal, corporate, and investigative professionals.

Tactical Performance & Design

• Invisible Interface: The recording mechanism is activated by a subtle slide of the pen clip, a natural gesture that draws zero suspicion during a meeting.

• Dual-Mode Operation: Features both continuous recording and Voice Activation (VOS), allowing the device to remain dormant until it detects human speech.

• High-Fidelity Capture: Equipped with an ultra-sensitive microphone tuned for human frequencies, ensuring every word is captured with forensic clarity even from several meters away.

• Functional Camouflage: It is a fully functional ballpoint pen with replaceable ink, ensuring it passes even a close physical inspection or request to sign a document.

Its slim, balanced design ensures it looks identical to a luxury office tool, providing a silent, reliable witness that stays with you in every sensitive conversation.
