I love my DT-250's, but I'm getting a bit bored of them. I thought I might try out something a bit more lively. I've tried Sennheiser and I find their sound like somebody switched on the Rock equaliser. Quite hollow in the mids. I've tried ATH-M50 and they sound amazing but on poor recordings they sound god awful. Also I imagine they get quite uncomfortable after a while. I have a big head. The ATH-AD700's look of interest, but I can't find anywhere in Sydney I could try them out. Has anyone got any suggestions on places or headphones? I currently use an ASUS Essence STX and iTunes. Mostly listen to rock, trance, metal, hip-hop. Biggest concerning factors are comfort, sound and price. Also, does anybody else find that switching back and forth from different headphones/speakers really make you overly aware to each device's shortfalls? I'm sure if I listened to nothing but my DT-250's for a month I wouldn't be so bothered.
