MBG line® Q85 discreet spy voice recorder – maximum performance and total invisibility
The MBG line® Q85 is an advanced mini spy voice recorder designed for users who require long recording time, high audio quality and complete discretion. Its compact size allows it to be easily hidden, while the absence of LEDs or sounds during operation ensures that nothing reveals its true function.
Up to 300 hours of recording on a single charge
Thanks to the built-in 1750 mAh battery, the MBG line® Q85 can record for up to 300 hours continuously. The internal 32 GB memory allows storage of up to approximately 384 hours of recordings, making it ideal for long-term monitoring and evidence collection.
Intelligent sound detection – record only what matters
The device supports both continuous recording and sound detection mode. When sound detection is enabled, the recorder automatically starts recording only when ambient noise exceeds a certain level. This saves memory space and makes reviewing recordings faster and more efficient.
High audio quality and ultra-sensitive microphone
Recordings are saved in WAV format at 192 kbps, ensuring clear and detailed sound. The highly sensitive microphone can capture audio from distances of up to 10 meters, without the need to place the device close to the sound source.


Built-in strong magnet – flexible and discreet placement
An integrated strong magnet allows the recorder to be securely attached to metal surfaces such as furniture frames, shelves, vehicle interiors or metal structures. This enables stable positioning while keeping the device completely hidden.
Easy operation and instant playback
Operation is extremely simple – just slide the switch to select the desired recording mode. Included headphones allow direct playback from the device without connecting it to a computer. Fast-forward functionality makes navigating through recordings quick and convenient.
USB flash drive function and OTG support
The MBG line® Q85 also works as a USB flash drive. When connected to a computer, recordings appear as standard files that can be easily copied and archived. The device supports OTG functionality, allowing connection to selected smartphones that support this feature.
