By its intra-canal position, ORISON uses the ear, which is an anatomical amplifier. Thus, the benefits are numerous : three-dimensional localization of speech1 thanks to the pinna, which captures and spatializes sounds ; no amplification of parasitic noises, such as wind noise, since the microphone is sheltered in the auditory canal2 ; instantaneous sound reproduction, thanks to the proximity of the tympanic membrane ; natural hearing and excellent user feedback.
