An ear protection device (10) to fit in a user's ear comprises an inner core (20) of non-compressible rigid material which is a metal or ceramic, and a compressible and resilient suspension layer (40), covering at least part of the inner core (20), for suspending and cushioning said device in a user's ear. The suspension layer (40) may comprise memory foam. The materials of the inner core (20), and of the suspension layer (40) differ very significantly in their characteristic impedances, so sound transmission from one material to the other is inhibited, and sound propagation through the ear canal is very largely prevented.
