Has anyone done that successfully? If they are truly DIN this may not apply, but I adapted Tandberg (TLH-74) headsets for Digidesign Audiomedia 1 cards with mono mic and dual mono outputs, anyway here are my notes: Wiring (Nexus plug) - Tip = headphone white = +. - 1 = headphone grey = ground. - 2 = microphone +. - Sleeve = mic ground. For sturdiness you might want to use heat shrink tubing over your dressings. Bob Majors
