My first set of headphones, beyond those that came included with my walkman radio/cassette and cd players back in the 80s/90s or the earbuds that came with my iphones, were something I'd researched and held out for for quite a while - Grado RS1, and by the time I could get them, it was the 'e' version that was out. Took a while to finally commit to the purchase having never actually heard them before - I was going on reputation and online reviews alone. Grado direct couldn't ship here, but Crutchfield had them hand delivered by UPS in three days and didn't even charge for shipping.
Crazy thing was, after a few hours of use, I hated them! LOL Man did they hurt. Those hard foam on-ear 'pads' totally ruined what was otherwise great sound because they were digging in enough to leave indentations at the tops of my ears.
And so they sat in their box; virtually unused because I'd never give them more than 20-30 minutes before refusing to wear them any longer and deal with that pain - a month'd go by and I'd try them again, always coming to the same conclusion. So they sat for over a year and a half barely touched...
Then one day while looking on amazon for replacement earpads for a set of Yamaha orthos I picked up, I saw a shopping suggestion about replacement aftermarket Grado earpads and followed the link, and man I'm glad I did. It was for a set of larger bowl style over-the-ear earpads, the G-Cushion like what Grado uses on their high end models (never even dawned on me that was an option prior to that moment). Figured it was worth a shot since the physics of moving the clamping force off of my ears with these larger pads made sense for better comfort - maybe they'd finally be comfortable enough to enjoy them. Short story even shorter -
those pads made all the difference and totally rescued these RS1e from their box. They're a real treat to listen to now. Looks like amazon's out of the pads I ordered from earzonk, but I did see other aftermarket bowls offered in their suggestions - if you have a set of Grados and hate the smaller L-Cushion that came stock on them, I would absolutely recommend trying this G-Cushion style pads instead.
