Headphoneus Supremus
I called Grado's number as listed on the website (somewhere in NY, IIRC). The headband costs $50 and it's quite easy to install - it's actually the entire assembly (leather part, metal gimbals, horseshoe holders, etc). Here is a picture of the stock headband:
To remove it, just pull apart the horseshoe and the entire driver cup will be detached:
Enjoy your more comfortable and classier SR225!
EDIT: Regarding the RS-1 vs. RS-2 headbands: the RS-1's gimbals (the metal rods) are of a higher quality and it uses circular metal holders rather than the plastic horseshoes of the RS-2 headband. However, the leather part is exactly the same - both the RS-1 and the RS-2 use the same exact leather part in the headband (which is more present and supple than the SR325's leather). The other RS-2 headband assembly is of the same weak build quality of the SR60/80/125/225/325; the RS-2 headband is basically an SR60 headband with RS-1 leather instead of cheap plastic.
