Posted in the DIY project thread here. The stereo effect obtained with these is great, I was surprised at the quality. Used the Panasonic 61a microphone capsules soldered onto the headphone cable that came with the cheapo headphones. AK_Dinosaur_Ride.mp3 The above is a recording I made with these. Made the battery box in the DIY thread too, attached these to that and then into a Sony RH1 recording in Hi-SP mode. The ONLY problem I had with these is wind noise, which actually caused an edit at the end of this file. It's tough to hear I think, but the last part I needed to replace the audio with a second ride through that didn't have the wind noise. I will be altering these to include a windscreen of some sort. Overall though, I can't complain. I figured I save myself over $100 by making my own stuff, and the quality really is tops.
