If you are under a limited budget I'd go with some AKG240 I have them and they are quite nice and quite unbias they are pretty good on the low end, I don't know if they are 100% Neutral but for the price they are pretty damn close. You can get them on amazon for 90$. The AKG240MKII,
On a down side if you really crank them things can get a little muddy, but for recording it is completely foolish to crank the volume all the way anyways.
**** those beats by dre I mean seriously they have trendsetter written all over them. My seinheisser cx-500s would destroy those pos HAHA.
