I use this headphone for a year and a half on my first listen I have not really felt much but as time collapsing these headphones become more and more of impressed.
The listening quality is really perfect crystal of acute, severe, not sloppy and not "disco" there are clearly defined and such a medium. This headphone is made of quality for quality, the music on low quality (120 kbit / s) means default is really all we feel that the sound is "compress" but that one passes the 190 (CD quality ) or 320 it becomes sheer madness! means all is when I told her all the slightest sound in the back!.
I shoot with a Denon AVR 3803 (800 euro) an equalizer Red / on (vintage) and a mixer BST (vintage) to double equalization. Sound combine to become the true vintage sound delirium is the end and pure.
The headphones are extremely durable, many other headphone is released with much "Equalizer" but not the HD 600 is still alive aprer 1 ½ years of use and the Equalizer is perfect you imprassion of be pregnant with very high quality headphones.
Only problem in the short time become less present at low sulfide and as it ages but nothing very serious.
I also use it in a mixing Synq SMX 3 and plate 20 is that CFX is of pure happiness <img class="smiley" src="/images/audiofanzine/interface/smileys/icon_wink.gif" alt="" />
If you say was an audiophile who demands the best quality sound without limit and with incomparable strength the HD 600 will be a nugget of gold!
The 280 euro price for me to deliver nine in a box with a port jack plate "or"
If I had the choice again I would without hesitation .... The HD 600 is an all new musical air!
