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.
