One of the causes of hear loss
As reported in an article about the middle ear infections by the Mayo Clinic (Arizona, USA): “Persistent infection or persistent fluids in the middle ear may result in more significant hearing loss”. Therefore excessive sweating with consequent increase in the secretion of wax will help the proliferation of bacteria or viruses in the middle ear canal. As we can read in the same article: “If there is some permanent damage to the eardrum or other middle ear structures, permanent hearing loss may occur”. This is why it is extremely advised to use in-ears made of a material that adapts to your body temperature thus reducing sweating.

Contact dermatitis and allergies
Referring to a publication issued by WebMDMedical Reference and reviewed by William Blahd, MD on September 24, 2017: “The skin inside your ears can itch because of an allergic reaction. […] Plastic, rubber, or metal you put inside your ears, like earbuds or a hearing aid, can also cause a rash called contact dermatitis.”. Allergies may cause swelling of the Eustachian tubes blocking proper drainage from the middle ear and cause dermatitis.
For the reasons above avoiding plastic and rubber materials while choosing in-ear monitors or in-ear earphones will also help preventing allergies.
