If you're talking about the Little Dot Mkiii, then look for a clean pair of
Sennheiser hd600's or 650's. If you want strong bass and highs, look
at the Beyer 990, 600 ohm. Another isssue is if you want closed or open
back cans. For closed, the Denon 2000, the Phillips Fidelio line and the
Audio Technica line have phones in your price range.
