1. A system comprising:
a hearing device; and
a charging device configured to provide a power signal to the hearing device while the hearing device is within a charging range of the charging device;
wherein the hearing device and the charging device are configured to:
establish a primary communication channel between the hearing device and the charging device, and
participate in an authenticated pairing procedure for the primary communication channel by:
the charging device transmitting authentication information to the hearing device by way of a secondary communication channel that allows for communication only over distances that are below a threshold distance, and
the hearing device using the authentication information to complete the authenticated pairing procedure;
wherein the charging device is configured to transmit the authentication information to the hearing device by way of the secondary communication channel by modulating the power signal.
