You are probably referring to the white little piece that is in the earhook that is getting clogged with moisture right?
You can take them out, but it does boost some of the frequencies just a little, which is usually not noticeable to most. In fact, I have done real ear testing with and without them (using speech mapping/VSM) and I could not measure a difference.
Yet, if that bothers you, you may want to dry out the hearing aid daily, using a product like the Dry and Store Global. You can also use other methods with mild heat to also dry them out, but you do need to proceed with caution there and, of course, any steps there are at your own risk.
You can also have your audio order more earhooks, which come with the white damper and change them out occasionally.
This is a common issue with this and other hearing aids that use a traditional receiver (speaker) built into the hearing aid and routing sound through a tube. This is not an issue with the receiver in the ear designs.
Yet, since Micro Power was discontinued, Phonak no longer offers a receiver in the ear hearing aid with telecoil anymore.
Thus Naida is the only option for severe losses that require telecoil for severe/profound hearing losses.
