These ear pads can be used with any of Focal's high-end headphone line-up (Clear, Elear, Elex, Elegia, Utopia.)
I changed my elegia earpad with this pad(stellia)
though it is not a bellilum plate, elegia plate is also very suitable with this stellia pad (sounds like stellia)
this is much much much muuuuuch better than dekoni custom pads.
if you have money, but don’t want spend many money for stellia.
this pad + elegia will be good choice.
