Warning Warning... Do not buy these HD599. They are not better then the 58x. The 58x beats them at every level richer bass, better detail more punchy. While the HD599 is more flat alot more flat. And on fit the 58x clamps on your head and 599 is more loose thats the only part i guess 599 is better at. But here is the warning. After aprox 14 months the leather part will crumble of the headband and guess what you can't replace it yeap it sux and Sennheiser in Eu offers 2 years warranty they say but won't cover it says they say its cosmetic which is bullshit it affects comfort yes not massivley but you feel it.
