In a binaural hearing aid system audio signals are transmitted between an antenna facility of a left ITE hearing aid and an antenna facility of a right ITE hearing aid. Binaural beam forming is based on a natural directivity of the pinna and/or based on a head shadowing effect. Each antenna facility has an antenna arrangement with a coil core made of magnetically permeable material, and extending along a longitudinal axis, a further electric hearing aid component, which emits electromagnetic interference radiation, and an at least partially planar shield made of magnetically permeable material. The shield is arranged between the antenna arrangement and the further hearing aid component transversely to the longitudinal axis of the coil core and the shield is arranged at a distance of 50 to 150 micrometers from the coil core, preferably 75 to 100 micrometers.
