Tried removing the grills, it seemed to open up the soundstage and remove a little grain from the highs. Not sure if others have had similar experiences but if I weren't worried about damaging the drivers I would keep this mod in place.
Don't ask me how, but this gives you almost the same results, but even better. I couldn't figure out why. When I removed the grill I was surprised how much clearer the sound was.
Then if you REMOVE the foam behind the driver the sound clarity goes out the window. What the heck?
Maybe the area directly behind the round circle part of the back of the driver has some sort of effect on the sound?
I've been bugging people to try this mod, but I think only one person has tried it. Trust me, the results are impressive. In older posts someone measured it.
Go to Michael's craft store and buy adhesive backed Creatology foam. It's the same kind in the Anax. HD-800 mod (I believe).
It's not that sticky and you can make it less sticky with your fingers.
Place a small square like so. Actually
much smaller than shown.
It takes 2 seconds. DO NOT remove any foam already in place.
The driver still "breaths" since the sides are still open.
It's possible you can use tape, but I never tried.
Ohh obviously this foam is with the grill installed.
I prefer the HD-580 to the HD-600, but with this mod the HD-600 is far better.
I still am baffled why this sounds even better than with the grill being open. I thought with the grills off the sound would be HORRIBLE. Not so..
Result:
Very slightly less mid and upper bass (I think). Slightly more than neutral bass to my ears. The mids are VERY slightly less thick/full sounding.
This leads to more detail, a clearer sound and even an impression of a larger soundstage. No kidding!
The thing is though that the HD-600 is now not quite as forgiving with bad tracks. It will only be as good as the recording.
Any really harsh tracks are not smoothed over as much. It may be a shock at first.
Basically to me this is the cause of the old Veil. When I added this foam it seems to remove what I dislike about the HD-600.
To determine the difference super fast, use these with a game such as Fallout 3 or Skyrim.
DISCLAIMER: I used this mod in place for a month. No my driver didn't blow up. The HD-600 seems built more like a closed headphone (just an opinion, sorry).
