I don't listen to any music files lower than 24bit/88.2 Khz so maybe that's why I don't find Tyll's version to be invasive, but having heard a few times that the liner version is better I'll give that a try. (I don't know who voiced the stock HD800s & to be truthful I think they were voiced to work with much lower priced equipment)

After listening to the HD800s for a while the "midrange" suckout on the HE 6 is really noticible, comparatively. I'll have to remember not to do that too often

Oh yeah, thanks for mentioning the liner goes in by itself

For more midrange presence, I recommend to use perforated felt disc inserted underneath pads on each side.

Give me a piece of Mahogany, several different templates & jigs, )access to different shop tools (stationary power & hand) & I can make a guitar neck . (It's been many years since I've made
anything this "ambitious" & I'm sure it would take me longer then it should, but it's "doable")

Working with "shelf liner" on the other hand is a much greater PITA. ( I know it's simply a matter
of a "piss poor" attitude & not getting "properly jigged up" to work with the stuff ; I need a stationary tool w/ a pull down lever & a perfectly shaped sharp cutter that will cut out the perfectly shaped pieces of liner on 1 pull of the lever; I told you a had a bad attitude)

My hand cut pieces on the other hand actually do work , but "they ain't pretty" & for no logical reason knowing they could be more visually correct will bother me enough to rip them out & start over ! Maybe not on second thought ! (Sorry if I bored anyone)

(This is on the pieces for the HD800/ which I'm starting to prefer over the HE 6) (No forget that;
the HE 6 just took a pretty nice step up the performance ladder w/ my adding small liner discs underneath the openings of the AKG K702 Earpads I'm using on the HE 6; so for "me" the HD800
go back to a subjective 2nd place)

Hi all, my first post here.

Good mod but seems to kill low bass of the HD800. Is there a way to fix the mod to keep bass performance of stock HD800?

I'm sorry, what?

Not sure what you did, but the mod should not affect bass response of the HD800 by any large margin.

Get rid of the foam ring underneath. A few of us don't use it anymore.
