Continuing the discussion from Field recording:
@lijnenspel, would love to hear your experiences when you get around trying the EM172.
Also, like @widdly, I’ve used class-compliant USB recorders together with my Android phone. It’s a great solution to capture a jam session, works in conjunction with video too (Open Camera app allows you to choose your audio source). But I’d love to have something more compact, a small electret mic (or a pair) that I could always carry around to capture an interesting sound.
The EM172-based Clippy would be great, provided that the 2v plugin power from smartphones is enough for it: http://micbooster.com/primo-microphone-capsules/98-mono-clippy-em172-microphone.html
