MQ350 Voice recorder with a huge recording stand by time.

The MQ350 Voice recorder looks and operates, just like an ordinary USB flash drive but conceals an ultra-sensitive microphone and powerful amplifier that captures voice conversations up to 12 meters away.

The recorder has a colossal recording capability.

The spy recording device records up to 16 hours of audio sounds and conversations. The spy device starts recording automatically as soon as it hears sounds. The standby will range up to 25-day standby on one charge.

This small but mighty voice recorder stores a whopping 288 hours of crystal clear audio, and records automatically so you won’t miss any crucial bits of the conversations.

The voice recorder has automatic sound recording as standard.

This Spy recorder has just one switch, disguised as a functional lanyard loop. To start recording in continuous mode, rotate the control towards the marker. For voice-activated recording, turn the switch towards the three small dots. Plug the MQ350 into any Mac or Windows computer for instant access to the audio.

Instant recording activation will ensure you don’t get discovered pressing start buttons. There are many devices on the market that record sound and audio but the MQ350 will outperform them all, it truly is a professional spy device.
