I was bored at night having a listening session so just to experiment I placed the yaxi pads from my koss porta pro in my grados not expecting much but danm now I get dankpods If you have grado headphones....go ahead and get some yaxi pads for them just like with koss headphones the foam is just perfect for them dont get the yaxi pads for grado get the ones for the regular portapros/ksc75 etc they sound awesome and feel way more comfortable at least to my ears the smaller footprint just makes then more comfortable to me with the yaxi pads being the same size as the driver they sound perfect to my liking and they look cleaner with the yaxipadi
