The HD600, although quen production for over a decade, is probably the best value on the headset market. It represents one of those rare cases where the performance level is so high for the price that we can use it as a yardstick against other headsets on the market. The bass, midrange and treble are beautiful, the tone is very close to neutral, with a pinch of heat and body. Of course there are better today, STAX SR-009, Sennheiser HD800, AUDEZE LCD-3 but in his category, I know of no other helmet that deserves such praise when you consider that the models I just mentioned cost between 5 even 15 times its price!
To me for 250 euros it seemed impossible to do better and then suddenly a miracle happened, a orthodynamique 400 euros or less, the 400 HE Hifiman
