I know, I know...
 
M50s are full size cans and Turbines are in-ear, but I have a hard time deciding which one to buy since they are close to price.
 
I plan on using it for my iPod touch/iPhone 4s 
 
I already have Astro A40s for my laptop so I won't be using the turbines or M50s unless I want to listen to music/watch movie instead of using the A40s since its made for gaming.
 
Or if anyone have any other earphones/headphones they want to suggest please do so.
 
I listen to dubstep/pop/electronic mostly, and watching movies/youtube

I'd say go for the Turbines since they are more bassy, and since they are IEMs, more portable. You might be effected by you laptop's probably-crappy internal amp though, since most of them are no where near as good as the iPod when it comes to driving IEMs
