How does one distinguish between earphones? There are headphones that sit on your ears, over your ears and those that are called earbuds and then there are insert earphones (slightly different to earbuds). How does one call these different types of earphones?
casque for headphones (we also use casque for helmet)
casque à conduction osseuse for bone conduction headphones
casque circum aural for Circum
casque on-ear for Supra
we do use the English to make distinction between these types, but it's to be specific, in normal life you will use casque
écouteurs for earbuds
I don't see what insert earphones are, maybe écouteurs intra-auriculaires if insert earphones = earbubs that go deep into the ear
