I put a lot of thought into buying decent headphones but someone ended up buying me a Sony MDR ZX 100 instead. http://www.sony.co.in/product/mdr-zx100    It has negligible bass according to some review I read (I'm an avid dubstep listener so I can't compromise with bass). Any idea on how good...

I was thinking on the lines of Vmoda bass freq or the ME M31, but I read mixed reviews for them. I owned a PL11 until yesterday (when it got ran over by a taxi). I'm an avid Drum n bass and Dubstep fan, so I can't compromise with bass :)
