I don’t really know much about ear hooks @anon99509572, except to say, they can be problematic, the white damper inside the ear hook, will occasionally swell up, with moisture, and completely seal the ear hook, so much so, the first time it happens, you assume the aid is malfunctioning, this happened on several occasions, with Naida Paradise & Naida Lumity’s, probably due to sweating, I have a box of spare ear hooks, so changing them, is a simple process, but it always happened at an extremely inconvenient time, so I just completely removed the damper, about 6 months ago, and the problem was resolved…I only use twin walled or extra thick tubing, this will give you approximately an extra 5db of gain on any , my A.uD orders it for me, usually in packets of 10, tubing should be changed every 4 to 6 months, or it will become too stiff, and quite hard, which usually results in the tubing, parting company with the mould, because of lack of flexibility, you do not want to be losing an expensive aid, so please change your tubing on a regular basis… Cheers Kev
