Replacement Ear Pads Compatible BTH240 BTH220, G330, Audio 478, Evolve 64, K420 K430 K450 K451 Headphone Memory Foam Earpads

My 3 year old .Audio 478 USB headset works great but one of the ea rpads was torn and falling off. The ear pieces on the headset are slightly larger (60 mm or 2 1/4" - 2 3/8" diam) than most other models so "typical" 2 inch cushion replacements did not fit. This product fits snugly and feels comfortable against my ear. Also I can wipe it clean. See photo of comparison of this product (left) to old foam cushion (right).

Nice and soft
