Oticon Opn S boosts the open sound experience

The upgraded OpenSound Navigator™ makes it easier for your patients to take part in the world. OpenSound Navigator helps people with hearing loss enjoy a full, balanced soundscape across all listening environments. Now, in a split second, the brain can decide who and what to listen to, and how to best switch attention when needed.

The new Opn S Very High setting offers even more help in everyday situations to the patients who need it most. And, Opn S gives patients the option to select extra support from OpenSound Navigator, regardless of their pre-defined setting. Whenever a patient feels they need an extra boost, they can activate the OpenSound Booster, available in the Oticon ON App.
