Thanks for ur reply, but i can´t buy those headphones from amazon, and i dont know any other global shipping web page that sells them.   Thanks for ur reply! So u think the k545 will be better than the ath a2000x or the Beyerdynamic T70P? 

Thanks, now i can rule out the dt990 and the m100s.   Anyone else have some opinion on the headphones i wrote there? gonna be waiting for other replys.
