Endoacustica Unveils the Micro GSM Quad-Band Spy Bug — Small Size, Big Performance

SANTERAMO IN COLLE, Italy - Aug. 13, 2025 - PRLog -- Endoacustica, a leading innovator in professional surveillance and intelligence equipment, proudly announces the launch of the Micro GSM quad-band spy bug. This cutting-edge micro listening device blends advanced engineering with user-friendly operation, bringing professionals and enthusiasts a truly powerful tool in a remarkably small package.

Designed for discreet use, crystal-clear audio capture, and global connectivity, the Micro GSM quad-band spy bug represents the next level in portable surveillance technology.

In the fast-moving world of surveillance, size matters — and smaller is better. But shrinking a device shouldn't mean sacrificing performance. That's where the Micro GSM quad-band spy bug comes in.

This palm-sized powerhouse packs in an internal rechargeable lithium battery, a high-sensitivity miniaturized Knowles microphone, motion sensor technology, and an integrated dynamic DSP processor for noise reduction. It's built to be small enough to hide almost anywhere, but strong enough to capture audio with precision.

From investigative journalists needing a reliable audio tool, to private security professionals working on sensitive operations, the Micro GSM is designed to give you quality, range, and flexibility — all without attracting attention.

The Micro GSM quad-band spy bug supports 850/900/1800/1900 MHz multiband frequencies, ensuring it works across the globe. With GSM/GPRS sensitivity better than -106 dBm, it can transmit audio from nearly anywhere a phone signal reaches.

One of the standout features of the Micro GSM spy bug is its selection of numbers for listening. You can pre-set numbers, giving you instant control over who can call the device and listen in. The motion sensor setting ensures the device is only active when needed, preserving battery life while keeping it mission-ready.

The internal DSP processor actively filters out noise, making sure you hear what matters. Whether you're monitoring a vehicle, a room, or an outdoor space, the Micro GSM delivers consistent performance.

Many surveillance devices work well in one environment but fail in another. Endoacustica built the Micro GSM to adapt. Thanks to its wide power range (5V DC or 6–30V DC) and optional tension reducer for vehicular use, it can run from a variety of power sources — making it equally useful for static and mobile monitoring.
