Planar Magnetic Headphones

I built a pair of planar magnetic headphones - basically just because I though the operating principle was interesting.  After several catastrophically bad-sounding attempts, I eventually built a version that sounded decent and looks pretty good:



The drivers are meticulously hand-etched from the thinnest flex-pcb material I could find.  The driver membrane is sandwiched between an arrangement of magnets embedded in the aluminum grill that makes up most of the structure of the headphones.

See the build-log here for details
