Skullcandy? Are you freaking kidding me? They sound **** as compared to its competitors!
If you want iem (in ear ones) then go for Brainwavz M2 at 2.5k from pristinenote/lynx
No competition to that.
In case of headphones,
Get one of these
Audio-Technica Headphones- T200, T500 , M20,M35 , AD300, AD500, AD700, A900
