Any of the Superlux range from THOMANN would suit you and your i pod. 668b/330/440/660 cant remember which one is the closed design. his site does akg240 replacement felt pads which really aid comfort.

Senn hd202S work really well with an i pod-closed design tough and cheap and sound really good for the price. I find senn really nail cable isolation and comfort. I own all of the above and 650s/700s so put my money where my ears are....
