These are filters for kz ed9. You get only one pair so choose carefully. The gold is the one with bassier sound while the bronze (actually it's mat gold) is more neutral sounding.
The sound of these earphones is great but the replacements I received had a big issue.
One of the filters was missing the mesh grill on the filter. Since I had only lost one, it didn't matter but generally these things should be checked before dispatch.
