Abstract: The disclosure relates to a hearing implant, an external hearing device and a hearing system wherein the hearing implant is implantable in a user. The hearing implant comprises an electrode array for stimulating a cochlea nerve of the user and a rechargeable battery assembly comprising a rechargeable battery. The rechargeable battery is chargeable by power or energy supplied by an external charging device via a wireless magnetic induction link.

Abstract: A monaural hearing device includes: a first housing accommodating a first near-field magnetic induction communication unit and a first magnetic field antenna connected to the first near-field magnetic induction communication unit, wherein the first housing is configured for placement behind an ear of a user of the monaural hearing device; and a second housing accommodating a second near-field magnetic induction communication unit and a second magnetic field antenna connected to the second near-field magnetic induction communication unit; wherein the first and second near-field magnetic induction communication units connected to the first and second magnetic field antennas, respectively, are configured to perform near-field wireless data communication with each other.

Abstract: The present disclosure relates in one aspect to methods of adjusting a second system clock frequency of a slave or second device to a first system clock frequency of a first device connectable thereto via a unidirectional or bidirectional wireless data communication link so to reduce clock skew between the first and second system clock frequencies.

Abstract: A hearing device system includes at least three devices configured to communicate wirelessly via near field magnetic induction wireless link(s) based on a predetermined communication protocol; wherein the predetermined communication protocol defines a frame comprising at least a first time slot and a second time slot; wherein at least a first pair of devices of the at least three devices is configured to communicate in the first time slot, and at least a second pair of devices of the at least three devices is configured to communicate in the second time slot; and wherein the first pair of devices is configured to transmit in the first time slot with a first transmit power level, and the second pair of devices is configured to transmit in the second time slot with a second transmit power level that is different from the first transmit power level.
