The Oticon Opn hearing aid features innovative BrainHearing technology, designed to support the brain’s natural way of perceiving and processing sounds, even in complex acoustic situations. The placement of the slim push-button on the device allows for easy and discreet adjustment of volume and change of programme. The extra-large battery compartment is especially well accessible. All essential components are nano-coated on the inside and outside, thus protecting the hearing aid from water and dirt.
