    256 MB memory

MQ-77 spy pen is very simple in operation - to start or stop recording just move the pens clip. Additionally, the device is capable of operating in sound activated mode. This function conserves memory of the device and also helps to analyse the recordings - the microphone collects only sounds of a sufficiently high intensity, so moments of silence are not recorded. MQ-77 comes with a 256 MB memory. Three levels of audio quality allow you to record from 8 up to 33 hours. A built-in battery lasts for 12 hours of continuous operation. An included remote control and headset allow you to easily control the device and listen to recordings directly from the spy pen's memory.

Strengths of MQ-77 spy pen

  • Discreet


    The pen can be comfortably used in any situation due to its inconspicuous shape. It doesn't arouse any suspicion, and is discreet and easy to use in any conditions.

  • Sensitive microphone


    Features a very high quality microphone, allowing you to capture sounds from the surroundings from up to 10 metres away.

  • Intuitive operation


    Operating the voice recorder poses no problems – stopping and starting recording is done by simply moving the clip of the spy pen.

  • Memory


    256 MB of built-in memory allows you to store from 8 to 33 hours of recordings depending on the selected quality.

  • Intuitive operation of a spy pen


    The spy pen allows for 12 hours of continuous recording, which gives you very convenient possibilities such as leaving the MQ-77 at home or in the office all day, and then reviewing what happened during your absence.

  • Intuitive operation


    An extremely convenient feature that conserves memory. When sound at the appropriate volume is detected, the voice recorder starts recording, automatically compressing any periods of silence.

  • Earphones


    The spy pen comes with a headphone jack, so that you can listen to recordings at any time.

  • Remote control


    It has a convenient remote for easy operation from a distance.

Comment : Very clever camouflage but the device itself is rather basic, not much memory and operation time could be longer

Comment : can be operated from a distance so no need to manipulate with it what may aroise suspicions. Simply put it on your desk or next to you at a meeting and use the remote when needed

Comment : I hesitated for a while if to go for the MQ-77 pen or VR-CA02 calculator (best solutions for an office environment I think) but eventually I got the pen. Quite straight forward and well camouflaged

Comment : At the beginning I was a bit reluctant to use this recorder during any meetings, because I thought everybody will notice that something is wrong but the pen is so discreet that it is impossible to spot the recording function. Now I use it at every business meeting I go to because you never know what and when may be said.

Comment : Best £100 spent in my life I suppose, just a shame about the circumstances I had to use this pen…

Comment : It's an interesting idea, a voice recorder hidden in a pen. It doesn't arouse any suspicion. MQ-77 is very simple to use from distance - remote control is small and discreet.
