Are Resound hearing aids waterproof?

Whilst you may see waterproof hearing aids advertised, in reality, while some models are slightly more resistant to water than others, there is currently no model that is truly waterproof. However, as a general rule, rechargeable hearing aids can be considered water-resistant, due to the absence of an opening battery drawer and some models such as the Phonak Paradise Life have extra coatings to protect against more water than standard models.
