All of our pens can be used to record meeting or lectures, however the PCM007 Ultimate Lecture Pen is the best in terms of audio quality and microphone sensitivity. The PCM007 pen is not considered a "spy" pen, but it is still a discreet audio recording device and will provide the best recording quality in a large room or a meeting where voices are further away. Check out our MQ77 and MQ9X models for a lecture/meeting recording device that is 100% discreet!
