UPS just dropped off the ear zonk pads, a set of G's, and a set of L's. VERY much initial impressions:
the G's very comfortable, didn't sound good at all to me with the 225, very little bass, lost the "up front" feel
the ear zonk L's on the 225 sound much better , i could live with it i think, but the stock grado may the way to go,
haven't gotten around to trying the zonk L's on the 60 or ms1 yet , here's some pics:
the ear zonks are a little harder to get on the cups
Sorry, I just can't endorse or encourage buying knock off pads, but maybe that's just me.
I do encourage folk to try the L-Cush and the TTVJ Flats for all their Grados except PS/GS1000
