Compatible headphone for Asus xonar dg 5.1 sound card

Any that use a standard 3.5mm TRS output and have an impedance less then 150 Ohms.

At the $50 range, I'd take a serious look at some of Grado's offerings. The SR40 might be the way to go. [Havn't used Grado's personally, but I've heard really good things about them]. Also might want to look into the Audio Technica ATH-m30.

Have a look at cans like the JVC RX700, Superlux HD668B and Samson SR850?

thanks guys for your replies.. I have increased my budget..now the budget is $120..please suggest some great headphone for this sound card for gaming purpose mainly and movie also.

More or less the same brands that we've recommended. They each of their pros and cons, but all offer quality.
