In fact, most of the hearing aids now have waterproof features.
But you have to be clear that this waterproofing is not absolute. The prevention of water vapor and the complete immersion in water are completely different concepts. Most of the hearing aids are now available.IP67-68The high-grade dustproof and waterproof grade means that it is not afraid of soaking water for a short period of time. However, if you want to use it normally, you should dry it in time and soak it in order to ensure normal work without sequelae.
At the same time, there is a kind of moisture that is easy to reach everyday, which is our sweat.
Sweat is not ordinary water. In addition to moisture, there is urea, salt, fatty acids and other ingredients in the sweat. These ingredients are undoubtedly a kind of corrosion for hearing aids. When we are sweating, we must take the hearing aid off and dry it, and then put it in the hearing aid drying box to absorb moisture at night.
Remember, there is no absolute waterproof hearing aid, and the moisture protection on weekdays is even more important.
