HI all,
 
  First post here !  However  I've been doing quite a bit of reading, thanks.
 
  I've just bought myself a set of HD600's.  On first listen I was very dissapointed, so much so that I thought my amp or something must be innapropriate.
 
  Three days later I'm thinking I may have a faulty set of cans.
 
 
  The sound I am getting is very bass heavy and lacking in high mids and highs.
 
  I have driven the HD600's with the headphone amp in my Sound Devices Usbpre 2, and also from my Sony PCM D-50. Both provide me with plenty of level and the exact same bass heavy sound. I'm aware that neither is a dedicated HP amp however they are also both very good units, especially the Sound Devices.
  The source has been both mastered music and self recorded files at 24/48 as well as Mp3's. The result always the same.
  I have switched in my trusty set of HD280 pro's and they sound fine (for what they are.)
 
  Is there something I'm missing here?   I've not experienced it yet but I read here about the sound changing over the first few hundred hours of use...  could this be the cause?  I mean, at the moment they sound terrible.
 
  Has anyone else encountered a dud set?    Are there fakes?
 
 
  Thanks for your time,  
 
  cheers,  Mikey

SUURE. I bought HD598 and when I listened to it out of the box, bass was somewhat ipod stock earphone-ish and everything was harsh. I even thought of returning them. Well, after 70 hours of burn in it sounded great. Start playing some flac files with wide frequency and you should hear differences.

I had some initial disappointment before initial burn in too. Maybe let them play a little before you come back to them.

Otherwise the 600s should be pretty neutral and have a mid emphasis if any.

Thanks guys,   I'll persist.  
 
  I'm listening to them now, although I've got the highs boosted to make them sound half ok.

It seems like a source issue. My set don't feel like they are anemic in the treble even when comparing to my more treble happy cans. They certainly don't feel bass heavy either.
