So I'm looking for an upgrading and I've been reading threads all over this forum. Basically, I want better mids, detail, and soundstage, while retaining SOME bass. 1) Ultrasone Pro 900 - way out of my budget range. I'm trying to go $220 max. 2) Denon D2000 - People say this thing breaks...

I have $80 XB700s, and while I would be doing a disservice to Sony by calling them anything less than great, I want to do better. In particular, I want to tame the bass JUST A BIT, or alternatively raise the mids so I can hear vocals and instruments a bit better. I could go into the $100-$200...

I'm poor as hell, and I want to buy like ten of these.   All I am looking for is the best sound quality of any type of earbuds, headphones, whatever, anything you can put on your head that isn't a speaker, for $10, or $20 max.    The one I've most recently tried is a KOSS KEB-24 in ear...
