In another more specific example, the second hall sensor 7 is located in the second earpiece 2 at a position corresponding to the position of the first magnet 4 in the first earpiece 1. The position of the second magnet 8 in the second earpiece 2 corresponds to the position of the first hall sensor 3 in the first earpiece 1, so as to ensure that when the first earpiece 1 approaches the second earpiece 2, the magnetic field of the first magnet 4 acts on the second hall sensor 7 and the magnetic field of the second magnet 8 acts on the first hall sensor 3.
