I spent about 6 months a couple of years ago trying to solve an itchy reaction to hearing aids. I had worn them 20 years ago, and quit because of the itchy reaction, even with hypoalergenic materials. I needed them now, so started trying again. I tried a number of different alternatives to the regular plastic and ear mold materials, and reacted to them all. In the end I went to a Siemens dealer who ordered a pair of ear molds and Siemens gold plated them. They are expensive, but have worked for me. I wipe them down with an alochol wipe in the evening when I take them out and let them air dry over night. Then in the morning I wipe the inside of my ear canal where the mold seats with a light coating of Hydracordizone cream 1% and put in the aids. With this routine I can ware them all day with only an occasional itching reaction, which I eliviate by removing the aid and rubbing the canal. Don’t know if this will help, but was my solution to a very painful reaction to 4 different mold materials. It is true, that they are bright in the ear being gold plated, but I can hear now, so they are worth it. I ware a behind the ear aid, and do not react to the tubing that goes to the aid.
