This is really OT. I'm thinking of doing some experimentation with audio beamforming[1]. For this I need to construct my own headset microphones, with multiple microphone capsules per headset. Getting the capsules, the microphone wire and doing the soldering should be dead simple. But I have no idea as to what material to use for the frame. A very thick metal wire surrounded in some kind of foam, maybe? Wire is good because it's easy to form during construction of the headset, but bad because it's also easy to deform when using the headset. The ideal material would be some kind of plastic that behaves like thick metal wire until you bake. Then after you've baked it, it should behave more like the plastic used in ordinary headsets and headphones.
