The FX-03's 30-ohm impedance matches the audio output specifications that XP designed for the Deus, Deus II, and ORX headphone jacks, so the headphones deliver clear target tones without distortion or volume loss. Impedance mismatch between headphones and detector can cause weak audio, clipped peaks, or frequency response imbalance, but the FX-03's 30-ohm rating ensures proper electrical loading of the detector's amplifier circuit. Detectorists running high-gain programs or hunting in high-trash environments get consistent audio response across the full volume range without the muddiness or harshness that mismatched impedance introduces.
