Ah but I assume the earwax makes people deaf (sorry I do not have experience) while this is actually making your life worse (walking in the rain etc).

Never tried it so can't say about it. Regarding ear wax, I have a friend who is a musician. Since he was frequenting loud rehearsals his hearing begun to deteriorate but it was so gradual that it took him a while to realize he was loosing his hearing somewhat so he decided to got to an ENT. The ENT removed a large ball of wax from each one of his ears and his hearing went back to normal after that. It is possible that the ear wax was building up to protect his hearing from the loud environment he was in.

"Loud noises do not cause the ear to produce earwax as a protection mechanism. Instead, earwax secretion is triggered by physical contact. This means that people who wear in-ear headphones, earplugs or hearing aids are more likely to find an increase in earwax. For loud noises to stimulate earwax production, it has to produce significant sound waves that trick the ear into thinking there is physical contact. However, for this to occur, the noise would have to be so loud it would cause permanent damage to the eardrum as well as excruciating pain."

I personally get quite waxy when I listen to loud music. I never let it build up but immediate notice more wax than usual. Oh, and I use over-ear headphones. I tend to believe that frequent lound sound could produce waxy buildup, whether it is for protection or not I have no knowlede of but I am open to the possibility

Interesting. I religiously wear earplugs every night for sleep and haven't found an increase in earwax. I also tend to have pretty clean ears, not much comes out that is visible. I clean my ears with q-tips, every day after my shower so maybe that is part of it.

So neat how everyone is different in this relatively small regard.
