What does an IP67 rating for hearing aids mean with rain/snow and walking?
 
Hi guys. IP67 is an international standard for dust and waterproofness. So The first digit, in this case 6 means its dust tight and the second digit 7 means it immersable in water to 6 inches. My old phonaks were IP 54 so a good sweat and they needed drying.
