All Widex hearing aids are water resistant which means that they can resist water from sources such as rain, showering, etc.
But the water resistant doesn't mean they can be penetrated in water so the Widex hearing aids are not waterproof but they are water resistant.
So you can wear the water resistant Widex hearing aids out in the rain, shower or anywhere else that the hearing aids may get wet.
Just don't submerge the Widex hearing aids in water or go swimming with the Widex hearing aids otherwise they will be damaged.
But going out in the rain or showering with the Widex hearing aids on is perfectly safe and will do no harm to the hearing aids.
