dude. .in this budget. dont even start talking about neutral sounds, natural sounds etc etc.. your only decent option i believe will be to go for Creative. whatevers available from this brand in your budget.. creative will give VFM along with build quality of the components..dont go looking for brands like iBall, intex etc.. the wooden speaker series from these are very heavily marketed and really are very shitty speakers.. in this budget, you cannot have preferences like speakers having a neutral sound.. whatevers there is there. you really dont have options.. only thing you can do is adjust the bass and treble knobs which will be the only setting available in all these speakers..
