hi Jerg

Firstly, thanks for your posts! I'm almost following your recipe to the tee

I'm looking to seal those puppies because there's a lot of leakage between the cups and the pad!

The rings on the HE-6 (and my wood HE-560) are plastic, so there's a little warping when screwed back on the cups. I hope the aluminum rings will give any seal mod a better fit.

I'll probably deviate a bit and experiment with modeling clay first instead of silicon. Got this idea from you with using putty. I wish I can get a hold of that stuff that sticks new credit cards to cards (fugitive glue?) for a less permanent tweak.

For the HE-560, I'm still hearing a bit "shrill" up top but with shelf liner covering the entire driver, it's too dampened. I'll have to experiment a bit with the hole size. Or maybe add some fiberglass. Or maybe ask Bill P what he did...but of course, what sounds right to some might be fingers against a blackboard for others.

More experiments to do...

I am getting aluminum rings for this reason, the plastic ones suck and they warp. The aluminum ones are thinner (you can check on your HE-560) so you need to use something to make up for the difference, like a ring of felt or foam or whatever. But it would be an improvement to the plastic rings.

As for glue, look for "glue dots" brand, they also carry strips of adhesive (not just dots) that is like the credit card adhesive. 3m I think.

I probably need to address the HE-560 mod elsewhere, but I've managed to tone down the highs a bit with the excess stuffing (silk?) from the back of the HE-6. I'm loving the 560 almost as much as the 6.

Anyway, still waiting for the aluminum rings to arrive before any further mods to either.

I tried the temporary electrical tape (external) seal of the ear pads to the cups for the HE-6. See HF post on the technique on the 560: http://www.head-fi.org/t/738912/he-560-enhancement-mod-v1-5/240#post_11363521

Slightly more bass to the already excellent bass of the HE-6 (with the mods). However, I DON'T recommend the electrical tape even for a temporary try at sealing the ear pads because when I removed the tape to install the aluminum rings, some of the paint finish came off with the tape. Don't go there, unless your cups are already a bit abused.

So far I had the Al rings installed in the HE-6, and the rings as mentioned by knerian are a bit sunk into the cups. I put the ear pads back into the rings for now as I don't have time to do the seal mod. But I found the sunken rings actually create a much more tight fit between the cups and the pads, even though it took a lot more fussing to get them connected. And the rigidness of the Al rings are much much better in keeping the pads against the cups.

Suggestion: don't have the Al rings flushed to the edge of the cups--the difference in height creates a better seal with the ear pads (barring going jerg's silicon method)

Oh that is indeed very interesting, I may steal the rings from my abused 560 to try that. I thought you would want it flush, that's a great observation.

That's a poor paint job if electrical tape pulled it off

...or very good electrical tape.

Yeah, very disappointed as I got the HE-6 recently (although as a demo unit from a local vendor). It's just one small fleck of paint (like electroplating) that got stuck to the tape. Really like the piano black finish, so it's a shame.

I also find that the cups are not sturdy enough to resist small dinks (not visible from afar).

I'm hoping that HFM avails replacement cups for owners, well, if I ever need to repair them.

Has there been anyone who changed the color of the original piano black? or change the cup to, say, wood?

LFF would be the guy to ask.

Has anyone successfully replaced the headband on the HE-6? I'm particularly interested in the one posted in Page 1 (from Taobao). I've reached out to the seller (got a friend who can write Mandarin) but they haven't gotten back to us. My friend did say the TaoBao page explicitly mention the screws can be matched to whatever headphone the buyers might need.

You can try Hifiman Customer Service to see if you can buy a replacement (if out of warranty). They're actually quite responsive and pleasant to deal with.

If you want something entirely different for comfort reasons, can't help you there. Although there are mods (e.g., suspension straps, headband warmers).

Happy new HE-6 owner here. No mods yet, just pad rolling (velour, pleather, focus pad, and Shure 1540). I immediately swapped pleather for velour before listening (remembering velour>pleather for nearly every other Hifiman), then tried the others before coming back to pleather and thinking "why not?" I'm surprised to say I like the pleathers the most. Not as airy, a little more bass presence, but the treble is more controlled. Mods will change this, I presume.

What's all this talk about the Al mounting rings? I see them on the site, don't understand the purpose.
