Need a pair of IEM for 2k or less bucks

Hi,
I have Sony Xperia Mini ST15i. I listen to music only on it on the move. Now, the stock earphones are pretty good. But I want something better than that for less than Rs. 2000. (Can't increase it)

I don't understand many of the terms audiophiles used to describe the quality of audio equipment so I will try to state my requirements by telling you guys what kind of music I like to listen to.

I like Metal. My favourite genres are thrash and symphonic metal. I want everything in metal music to stand out. They shouldn't just focus on Bass. I want everything balanced. Metal doesn't sound so good on my stock Sony earphones. One of the primary reasons I am choosing to replace them.

Next, I listen to a lot of classical. Indian and western both. The classical music should sound clear and clean. They are quite good on my stock Sony earphones. So I guess I shouldn't expect much better performance from what I am going to buy.

I hardly listen to Pop music of these days. Also very little Hindi music.

I will buy the earphones from flipkart. This very week if I get good recommendations.

EDIT: Will also buy PowerAMP. (Do voodoo patches work on Xperia Mini?)
