    Abstract: A hearing device includes first, second, and third antennas oriented respectively along first, second, and third axes that are different from one another. The device includes first channel circuitry coupled to transceive and process antenna signals of each of the antennas. The antennas and the first channel circuitry communicate with another hearing device via a near field magnetic induction (NFMI) signal through a first near field magnetic induction (NFMI) communication channel. Second channel circuitry is coupled to transceive and process the antenna signals of each of the antennas. The antennas and the second channel circuitry communicate with the other device via the NFMI signal through a second NFMI communication channel. Third channel circuitry is coupled to transceive and process the antenna signals of each of the antennas. The antennas and the third channel circuitry communicate with the other device via the NFMI signal through a third NFMI communication channel.

    Abstract: An ear-worn electronic device includes a housing comprising a first end and an opposing second end, a first side and an opposing second side, and the first and second sides extending between the first and second ends. The first side is configured to contact the wearer's head. A battery is disposed within the housing proximate the first end. An acoustic receiver or an acoustic receiver connector is disposed within the housing proximate the second end. Electronics including a near-field magnetic induction (NFMI) radio are disposed in the housing. A directional magnetic antenna is situated in or on the housing and coupled to the NFMI radio. The antenna comprises a core having a complex shape and a coil wound around a portion of the core. The core comprises a closed end oriented toward a source of magnetic noise and an open end oriented away from the source of magnetic noise.

    Abstract: Disclosed in some examples are methods, systems, apparatus, and machine readable mediums which mitigate multipath fading and extend the robustness and the useable range of the wireless link between a streaming device and a hearing assistance device. In some examples, this may be accomplished by utilizing redundant wireless sources of the streaming data—that is, multiple copies of the streaming information may be sent to the hearing assistance devices. To prevent interference, at least one transmission parameter may be varied between the transmissions (e.g., frequency, channel, time, coding, or the like).
