Some helpful links for you:

Here's the adhesive felt I used for the HE500 fuzzor. It comes on and off easily with very little residue:

Here's the link to the adhesive foam that I mentioned (often used to tame the treble in the HD800 & Beyer T1):

I haven't tested the foam yet, but with all that plastic in the he400 cup, I have a feeling it might work.

For anyone outside of the US
Try this: http://www.ebay.com.au/itm/390871040382?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
They come in many colours but I dig the red felt. 1mm thickness too.
When it arrives and I've installed it, I'll give impressions

I'm gonna jump on this too. I am liking the Beyer sound so I figued these could be up my alley after reading so many reviews.....again- the HE-400. So I opted to part with my HD650s over these after comparing the two for quite a few hours over different genres. I never used these much due to their weight and fit but remembered there was something I liked about them so I kept them to work on later. Alot of it is they seem a better build quality than the HD650s. The Hifimans seem a lot more durable but certainly not as light. I don't deel like I have to be as careful moving them or putting them on my head. Grills are very stiff and durable. Fast forward to a few days ago. So far after pulling these out, I am finding they are irritating me after a bit. I think I could like these with the fuzzor mod... as the sound balance really isn't that far off from my preference as of lately. I've gravitated toward slightly bright phones recently with less bottom end quantity, not quality. I am liking the flatter sounding cans over the smiley face and mid heavy stuff. To me the HE-400 is more capable than the HD650, which to me is veiled sounding. I am trying to get as neutral a sound as possible without being veiled in either end of the spectrum or the middle for that matter. Or an irritating high frequency ring as is present in stock HE-400. It hurts! But if it wasn't there, these would be sweet! The Hifiman HE-400 are not really as bright as the Beyers and certianly not overdone in bass either. Actually a good balance the more hours I put on them.... other than that damn standing "hollow sounding" high pitched ring. Almost can describe it as a closed can phenomena. I can see why people change the grills out for more breatheable ones- it lessons the "ocean" effect. It seems my limit on the HE-400 is about an hour and I'm fatigued. I'm gonna wander over to the crafts store to get the thinnest adhesive felt I can find. My question on the HE-400. Is it best to make big felt disks and cut out the inner square. Then fill in the strips? I notice there is open space under and around the plastic frame on the sides. Is this open space needed or would it be better to cover them with a big round felt disc with the square precisely cut to fit the center square?  Understand?


I added this photo from another Headfier's ad as it had the only pic I could find of a fuzzored HE-400 :^). Notice all the plastic in a circle that isn't covered around the center square. That's what I'm thinking of covering, including over the gaps betwwen the plastic that isn't over the planar ribbon.. Or is that just too much? Of course I'd leave it back a fuzz (no pun intended) so the pads fit in easily still. Anyone tried this? I'm wondering if it would lose some body on the mids or have the opposite effect and focus them with out the added color of the open space. Am I looking at this correctly?

Not perfect by any stretch, but I did ok, I guess. Lol.

Something about the baffles and stuff on these reminds of when I did mods on a couple of pairs of AKG K340's in the past.

Looks pretty good.  I know we talked about the sound.  Hopefully your brain will adapt.  If not, it's always reversible/re-doable/reversible/re-doable/... Going through that cycle might almost make one believe in reincarnation, if one didn't already hold that belief ;)  But I think you know what I mean.  Eventually you'll figure out which sounds best to you.

 

Will you try it on the HE-6 when you get them?  I think some people have, but not being an owner, that info slipped through the mental cracks.

Thanks Thurston X!
Yes, I will probably do the HE-6 when I get them, if I get enough patience.
Lol.
Where is your description of how you attached the knock off AKG pads to the rings?
Maybe I didnt search the right post or far enough back.

To other folks out there who have tried it, is the fuzzor mod worthwhile on the HE-6?

What about the grill mod?

Or do they benefit the HE-500 more?

Start with this one and read on down the page

 

http://www.head-fi.org/t/551345/hifiman-he-500-he-as-in-high-end-proving-to-be-an-enjoyable-experience-in-listening/15810#post_11418098

 

After that you'll see one that's pretty detailed, mostly about what I did to mine specifically, and maybe why I did it.  As noted in a post or two after that, my elaborate mods are not necessary, just something I wanted to try, and the only thing you need to make those pads work for HFM cans is a way to attach them to the HFM mounting rings.  Further modding is left up to you and your imagination, with some generous contributions from jerg, a Master Modder ;)

I did the "fuzzor" mod on my HE-6 and I can safely say that I will never undo it. It's the perfect mod for HE-6 IMO. It tames the excess treble and enhances resolution, transparency and depth at the same time.

Please note that you most likely will prefer to remove the fibres and foam (and grill) on the outside too - after the fuzzor mod. This will open up the sound.
