Dear experts!!
Hi, I am in dilemma to choose which headphone or IEM.
bass headphone? studio headphone?

If i wish to able to listen clearly of how the background instruments are playing the flow.
My priority concern is can be listened clearly for differentiate of the flow of various background instruments? or great instruments separation (to listen to the arrangement of the songs)
I will buy a sansa clip+ or colorfly C3 or iphone for my music playback. (u can kindly recommend me on this too, thanks

)
which headphone or IEM do u recommend?
If you want separation and clarity go for BA type IEMs, if you want soundstage and bass go for dynamic type IEMs or headphones.
C3 is better than clip+ in terms of SQ.
For BA earphones you can look at TDK BA200, Final Audio Heaven C or S, Hippo ProOne, SE425, UE900, XBA-3, UM3x, etc
For Dynamic there's RE400/600, Klipsch X1, GR07, IE8, etc
