PilotUSA GoPro HERO3, 3+ and 4 Recorder for David Clark Headset PA-80D/HERO3
Most digital recorders have a 3.5mm AUX In for recording, however with the GoPro HERO3, 3+ and 4 they use a Mini USB port for recording. This adapter connects directly to the GoPro HERO3, 3+ or 4 Mini USB port instead of a 3.5mm port.
