At that price level I also second a Grado Prestige or an Audio Technica.If you listen exclusively to Jazz and Pop, Grado will take you to (relative) heaven, but it's abysmal for classical (to my ears). Has rich but muddy midbase that adds a lot of meat, but also adds a lot of mess.
Audio Technicas are much better for classical music, but might be too lean for many pop and some jazz. ATs have a leaner midbase, but very clear spectrum otherwise.
