First of all, i would like to say I'm totally happy to join your forum and it's my 1st post
 
So here's the situation:
 
I'm very addicted to listen to music (min. 8 hours a day). My current setup is iPod Classic 120GB with Sennheiser CX400-II. I used CX300-II about 2 years later, and happily invested to the 400's. But now, i wanna give the last shot of investment with buying a hi-end earphones. My choices that completely confused my brain are:
 
Turbine Pro Gold
Turbine Pro (Copper)
Miles Davis Tribute
 
Note: I'm listening all kinds of music (Jazz, lounge, metal, classical music etc.). The only thing i want is clear mids and highs without distorting it with bass. I'm not a basshead actually, but i'd like to hear accurate bass too. So, which one do i have to prefer? (By the way, sorry for my bad english)...

Awwww sorry, i posted it to wrong section. I didn't see the in-ear headphones section
