Abstract
This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer-readable media, for near ultra-low energy field (NULEF) headset communications. In some aspects, a source device, located in a seat headrest, can generate a modulated magnetic field capable of transferring data via a magnetic communication link, such as a NULEF communication link. The source device can establish a wireless data transfer session with one or more sink devices, and at least one of the sink devices can be implemented to receive data via the NULEF communication link.
