Digital Voice Recorder
This compact microphone is small enough to easy fit in a pocket or bag for taking with you to a conference or musical performance, but it doesn't stop there. It is actually multiple microphones in one, meaning that you can record stunningly clear stereo sound from this one compact device. For more information, check out the manual (pdf), or email mlab.
If you plan on doing some recording in your office, the mLab, or other stationary location we have a studio-quality condenser microphone (PDF) that plugs into your computer (or ours) via USB.
