Old decrepit earpads came off easily; have done it a few times previously to clean them.Instruction included are clear if you need them. Used the supplied tool for one side and didn't need it for the other. Helpful.Replacement pair look and feel identical to the original. They lined up and snapped on with relatively little effort. Tricky to snap on the 2nd half of each without applying too much pressure, but the originals are the same way. Final install feels solid and well-aligned.Haven't yet worn for an extended session, but the fit is seemingly the same, with glasses. Firmly grips when worn and the headset stays in place.Would buy again if they hold up as long or better than originals over time.Suggest having some painters tape handy to pick away old debris and clean the headset while the earpads are off.
