I'm so crazy about Classical music that I want to do it professionally and so naturally I want some really excellent headphones. I'm looking for headphones under $90 that are clear and crisp treble, effective strongs mids, colorful, and punchy tight (not boomy) bass. I listen to all types orchestra, solo, chamber. I've had the Klipsch S4, but sadly after 2 or 3 years I lost them now, but they were AWESOME! I also want headphones that sound so full and strong and also feel like they're playing right in front of me, but with a big enough soundstage to really feel like the music surrounds you when it's suppose to be epic like Stravinsky's Firebird.
