I ordered two sets of these ear pads, not for Grado headphones, but for Radio Shack Pro-60s. They were glued to the Pro-60 pad mounting rings and then auditioned. The sound - very good (!) with my Sony receivers after pulling the bass back to an 11:00 setting with a touch more highs-and-detail than I remember from box-stock Grado 125 and 225 headphones in the same receivers. A quite positive result for these old Radio/Shack Frankenphones. TurntableNeedles' quick-shipping wizards had the earpads in my mailbox much quicker than I expected from today's sad mail delivery standards. Very happy with the all the results from this purchase.
