The albums I am most concerned about are 10/39 and Kerplunk from Green Day and Cheshire Cat and Dude ranch from Blink 182, but the software I use for playing my music (winamp) has an EQ slider. Does that fix the problem?

I am considering getting a new pair of headphones and as I am new to audio I'm not sure what to get. I listen to a lot of rock/metal. I like tight, heavy bass, good guitar with a lot of instrument separation. If I get the sennheisers I will be pairing them with a fiio e07k and the beyerdynamics...
