A wearable audio device with an electro-acoustic transducer for creating audio output, the electro-acoustic transducer comprising a transducer magnet that produces a transducer magnetic field, a magnetic field sensor spaced from the electro-acoustic transducer and constructed and arranged to sense the Earth's magnetic field, and a magnetic shield comprising a material with high magnetic permeability. The shield is configured to intercept at least some of the transducer magnetic field before it reaches the magnetic field sensor.
