Abstract:
A headphone includes an electro-acoustic transducer for creating audio output, the electro-acoustic transducer comprising a transducer magnet that produces a transducer magnetic field having a magnetic field strength, a housing constructed and arranged to be positioned at an ear of a wearer so as to direct the audio output at the ear canal of the ear, a magnetic field sensor positioned in the housing and constructed and arranged to sense the Earth's magnetic field, and a nulling magnet positioned in the housing and constructed and arranged to produce a nulling magnetic field that reduces the strength of the transducer magnetic field at the magnetic field sensor.

Claim (Index 10):
The earphone of  claim 1 , wherein the magnetic field sensor has a sensed magnetic field range where it operates linearly, and wherein the second magnetic field reduces the strength of the first magnetic field at the magnetic field sensor such that the sensed magnetic field strength is in the sensed magnetic field range where the magnetic field sensor operates linearly.
