My hearing aids came with a 60 day trial period. Thank goodness for that because very soon after getting them I did the stupidest thing. I wore them while blowdrying my wet hair. Stupid, stupid, stupid. The instruction booklet warned to keep the hearing aids away from 2 things: water and heat. Of course I learned this afterwards. Have you ever heard of a librarian who didn't carefully read an instruction booklet? Yikes.
Well, needless to say, soon afterwards the aids failed. I took them in to the audiologist and she sent them off for replacement. Fortunately it was during the 60 day period and they were replaced with no questions asked. Of course I had to live without them for about two weeks while they were getting fixed but I got by.
Then about a month later, one hearing aid failed and then a few days later the other stopped working. I knew I had done nothing wrong this time. I tried replacing the batteries with no improvement. What could be the problem?
I returned to the audiologist again this time in a little bit of a snit. If these things were going to be breaking down so often, what was the point of wearing them? Never mind that it was all my fault the first time.
If you wear hearing aids, then you probably know what the problem was. But for everyone else I'll reveal the culprit: ear wax. The audiologist unscrewed one earpiece from its hearing aid and placed a thin plastic wire inside the tube. She pushed out a clump of ear wax just visible to the eye. It was the same problem in the other one. "Stupid, stupid ear wax," she said. To myself, I thought, "Hooray, all is not lost. Ear wax I can deal with." In fact, the audiologist gave me a few of the plastic wires to take home so I could handle the problem on my own next time.
