i bought them from drew at moon audio.
i'll probably try to mess with the eq in foobar just to see if i can come up with a something...

That is strange. I recently had the 880/600 and they were smooth as butter from top to bottom. I HATE Beyer highs, very unnatural, but the 880/660 out of my Entech DAC and SOHA Tube amp were nothing but delicious. I returned them in favor of my HD580, but there was no signs of sibilance. Even Diana Krall had no issues and she has the most sibilant recordings I have heard.

Also factor in factors such as the inherit sibilance in the recording that other headphones masked over.
A great test for sibilance is the song True Faith by New Order. There's alot of sibilance in that recording.

Let me try to help you...
 
The most easy thing to do is install some foam/fleece/felt or whatever on the driver. You can do so by taking off the pads, the plastic ring and the Beyer foam. You simply put your desired dampening stuff on there and put everything back together. Super easy and might be the sound you're looking for.
 
Another option is Jmoney pads; they tame the highs. I personally wouldn't bother with them though. They make the sound very artificial and too hollow.
 
The best option that I have come across is Noxter's closeback mod. What he does is close the entire cups by means of tape and dampens it with felt. You'll need a small breathing hole however if you like your bass. Here the front of the drivers also need some dampening as well. The mod needs DT770 pads to work.
I currently have mine modded this way. It definitely kills the hot treble. The amount of bass/mids can be tuned to your liking via the breathing hole. The closeback is just overall a more balanced can than stock. Check it out I'd say.

thanks, apatN.
is removing the beyer foam reversible?  in case i wanna sell these?

 

[apatN]

Yeah absolutely. It is only held in place by the plastic ring which I must admit can be a little tricky to remove for the first time. Don't pull it out with your fingers but rather use a small screw driver or a knife (be careful with the drivers!!) to pop the rings out.

 

[TheWuss]

HOLY SMOKES!!!!  IT WORKED!!!!!!
 
WOOOOO-HOOOOOO!!!!
 
okay.  i need to calm down. 

 
i went to the local wal-mart, bought some craft felt.  popped out the beyer disc/foam, and laid in some craft felt.  i heard a little difference.
so i popped in an additional layer... and, voila!  highs are nicely attenuated.
 
and, guess what, the sibilance is greatly reduced as well.
 
yeeeeee ha!!!!

 

[plonter]

nice to hear you fixed the problem

  now you can really enjoy your beyers!

Great to hear that it worked and I am glad that I could help you out.

Should you want to mod them a little bit more, make sure to check out the closeback mod. Make sure to post your findings.
 

 

[TheWuss]

thanks, apatN.
yeah.  i will check out the mod thread.
some time when i'm feeling more adventurous, i might give that a go. 

 

[happyxix]

I just received my DT880 250ohms (because I didn't want to pay the $60+ premium for the 600ohms) And straight out of the box OMG HARSH TREBLES!!!
 
Yea same as you feeling somewhat. These however are not as sibilant as the HD800 which made me hate listening to some music. But I eqed and its better somewhat. How well does that felt mod work? I know it sounds like you are super pleased with them but after a few days to calm down are they still as good as you initially thought?
 
These are interesting phones. I still haven't made up my mind if I like them yet. All I know right now is that they really don't give you enough clicks on the headband... Damn you massive head.

 

[TheWuss]

yeah.  i'm really, really content with how they sound now.  i listened to them yesterday for about 3 hours.  which i wasn't able to do before.
 
the trade-offs with the felt mod are very favorable to my ears.  it rolls off the highs, bringing the treble more in line with the mids and bass, to my ears.
 
i think you can actually make them a "bordering on warm" set of headphones if you wished.
 
i think what i'm hearing in terms of unwanted effects is a very, very slight smearing of the lower mid and upper bass details.  but, i'm not sure if that's the result of the felt, or that it's always been there, but masked somehow.
either way, it is very minor, and the overall sound now is nice...
 
also, i've noticed that the "focus" of the headphones have changed somewhat.  the sound is now more centered around the mids rather than the treble, to my ears.  and this helps also with impact sounds such as snare and toms, and upper bass notes.  it's really nice.
 
i'd say that the imaging is the same, but perhaps the final bit of air and detail is lost up high, and the sound stage, i'm having a hard time figuring out how much it's effected.  not too much.  it certainly doesn't suffer to any degree that i can gripe about, considering how good they sound.
 
so...
what i did was bought some craft felt from wal-mart.
then, i removed the ear pads, and cut the felt into several circles the size of the beyer foam inserts.
next i popped out the beyer foam with a flat head screw driver.
then i placed the new felt in its place, and replaced the ear pads.
i wound up using two layers of felt.
 
the only trick is, you'll be challenged to not scuff the headphones a little bit when you remove the beyer foam/disc.
if you're concerned about that, it is also possible to lay the felt on top of the beyer foam.  but, this makes the resulting layer of stuff pretty thick, and will encroach on your ear's room a bit.
 
laying it on top of the beyer foam pushes the "effective" layer (the felt) further away from the drivers.  so it's marginally less effective than applied directly over the driver. 
 
but, i listened to it both ways, and had a hard time figuring out which i liked better...
 
the nice thing about the mod is it's reversible.  and, you can do one layer over beyer foam, or 1 layer instead, or 2 layers instead, etc.
 
you can also try different materials.  heck, even ordering acoustic material made just for this purpose.
 
you can get colored felt, for a blinged out inner ear cup color.  i bought black, and now i wish i had gotten red or something exotic.  hahahahahaa.
 
i know ZombieX used Viva paper towels in his beyers, and was pleased with that.  hahahaha.
i'd imagine those would get dingy after a while, but oh well.
 
i also didn't try popping the beyer foam back in after applying felt.  i don't think it would snap back in, as there's something there in the way now....
 
so, try the mod out.  it worked super well for me!

Try cutting the felt slightly smaller than the Beyer foam pieces. It sounds like you cut the felt the exact same size as the foam and when you layer that all up there won't be room enough for the plastic rings to "fall into place". If you cut the felt slightly smaller the plastic ring should have room enough. On top of that felt you place the original foam layer (to mask up all the ugliness) to hold the felt into place and the plastic ring should still have enough room.
 
I second the use of different materials. It's all about finding the right stuff for your ears.

ah ha! 
see, i was concerned of treble escaping around the edges.  hahahaha. 

i'll have to go back and do some trimming and see if i can get the beyer discs back in there....
cool.  thanks again as usual, apatN!
 

 

[apatN]

Treble escaping around the edges. Hahaha, you made my day.
