My HA’s are IP57 rated:
"IP57 indicates that the hearing aid is water resistant and dust protected. It survived immersion in 1m of water for
30 minutes and 8 hours in a dust chamber as per the IEC60529 standard"
The real world is that I got caught in a hard rain for about 30 seconds in July 2014 before I could get under cover. The left one was not working when I got inside. After two days in my dryer it started working again and then two weeks ago it died completely. It was replaced under warranty.
Remember that the sales rep only cares that his samples are working immediately after the demo is over. In real world it is our money that we are risking. I view water resistance as a plus, but I’m not going to intentionally tease the gorilla by putting them in water.
