These are BRAND NEW NEVER USED NYCCAJ SLIM GIMBALS AND RODBLOCKS SET FOR GRADO ( currently on sale $110.00 + $11.00 for shipping) + PREMIUM SHEEPSKIN HEADBAND CUSHION($27.99) from AMAZON.

I was planning to install them on my PS500e, but sold it because i prefer my RS2 vintage button. The kits will make your headphones much more comfortable than the stock one, save you a little bit of money and shipping time from Poland.

Price included PayPal and shipping fees, if you have any questions please PM me and thank you for checking out.
