hmm this is always a hard topic mate, headphones are very important, a shit pair can even hinder your mixing, but in saying that as a beginner with im guessing beginner gear you dont want to be forking out $300 on headphones hd25's can be bought pretty cheap and are a great starting point and you wont really need to upgrade, most of us on hear love the xd53's and im pretty sure 8/10 regular members on here use them i started with cheap Sony mdr700's i think they were called, they were decent for cheap phones, i think i payed $60 for them...much better then say "Skull Candy's" which would cost you more (i dont recommend that brand)
