I do not think that the water will be the problem, more the stuff that is disolved in the water and will be left when the water is evaporated, just a thought..

That is a problem also, but water can wick into small tubes and essentially never evaporate due to surface tension, blocking the tube.
I have experienced improvements in sound after using the dryer with some of my more well used CIEMs, and especially those with smaller diameter sound tubes.
Hi KimChee, I use the dryer regularly with various CIEMs, usually before I put them away after reviewing them. I need to buy desiccant packs for my storage as my use is just different than most other people. I can say that if I think something doesn't sound right I stick it in the dryer and things go back to normal.
And as far as the cable I was going to report back on, it did continue to green, so I am not sure if the water molecules bond with the copper and will oxidize no matter what.
Thanks Joe I didn't get the hearing aid dryer, but I got a dri-eze dehumidifier. I must have had driver degradation because after storing them it's like a veil was lifted. My highs sparkle again and clarity is back. Thanks for making us aware of this.
This is known in the pro and hearing aid markets, but I hadn't heard it mentioned on head-fi before (although it may have been). Glad you got positive results, can you link to what you bought?
