Important notice

Use a specialist for repairs and servicing. Never attempt to repair your hearing aids yourself. You may cause more damage, which may be irreparable. Check the instructions for use that came with your hearing aids for more details.

Always contact your hearing care professional if you are having problems with your hearing aids.

Taking good care

Oticon hearing aids are manufactured with tiny components and intricate circuitry. When used correctly, they will improve speech understanding in noisy surroundings and the ability to localise sounds. To take good care of them, avoid exposing your hearing aids to heat, humidity and chemicals.
