These pads fit the following models from Audio-Technica: ATH-AD500X, ATH-AD700X, ATH-AD900X, ATH-AD1000X, and ATH-AD2000X. By using a tighter velour, Dekoni made the ear pad react more like a traditional leather or protein leather ear pad in that you don’t lose the bass frequencies or the isolation as seen with most velour ear pads, all while retaining the comfort and coolness of velour.
