Well, I HIGHLY suggest these. Sony MDR-XD100. I have had a pair of these for about a year and when I plug them into my amp and play for the same reasons as you, it sounds fantastic. Also, if you plug them into your computer they sound great.

Also, they are fairly cheap. For sure in your price range.

Here is a page I found with some information on them. and you can also do some research on your own. http://www.abtelectronics.com/product/17762.html

If you got google "todd the vinyl junkie" and buy off of them you get a 10% new member discount on your first purchase. He also had a massive selection of great audiophile gear. I recommend buying from him.
It's really hard to go wrong with Sony MDR-7506s. For $99.00, they're a steal. They sound great, have a 1/4" and 1/8" connector, and fold down for storage.

I have about 10 sets in the studio and use them for monitoring and mixing.
