I have a drier, but have not used it with my K10s. A few years back I had all sorts of problems with silicone customs. One or more of the drivers would repeatedly fail and I was told it was due to moisture, so I was given a complete new set and a drier, but they still failed. I have had no issue with any other IEMs. The Lear manual say not to expose their IEMs to UV. They have acrylic shells, so maybe not a good idea to put your Noble customs in a drier with UV light.
