^^ the beauty of any opinion based discussion! Out of all the headphones i have i find the K612's to be the best all around. The K7XX and K340 do jazz better but the K612 is close, the HE500 does vocals and classical better but these are no slouch. The DT770's (imho)only have marginally better bass impact and that's if im splitting hairs. Also i like tube amps specifically for the way it aftects the sound.Best bet is for Benjitb to try it himself.
