The two don't conflict. The regrilling mod (without any fabric especially) basically expands the openness of the sound outwards ad infinitum, it's very beneficial toward realistic rendering of live recordings (concerts / orchestral / ensembles). It gives HE500s a truly black background.

 

The jergpad modifications are on the other hand, modifications that carry out changes on more concrete things (tonal balance, extension, and removing cupped-ness to some degree).

Since I normally listen to EDM, I'm not sure I want any more openness than they already have, I could be wrong though. I guess the only way to know is to try... though I like how their current state is probably the most protective for the driver.

It's not openness as in more upper treble, but rather more openness from elimination of the greyness in the background from the minute reverberations off the stock grills (metal/fabric and all). Truly black background = real airiness and clean treble.

 

Words don't mean much when describing these things though. You won't know until you try.. take the grills off and try some live concert/orchestral music with or without the grills being held across with your hands.

Yeah, I'll have to try this. Just as long as removing them doesn't make them airy in a not-so-punchy-bass kind of a way... if that makes sense.

In fact bass gets lighter as you obstruct the backs of the drivers more, so no worries. HFM HE series of planars are more or less air-damped.

Damn you, jerg! How your mods smite me... I guess I have a weekend project.

I agree!! The grill mod gives more air and blacker background... It complements the jerg modded pads perfectly! But..on,y way to find out is to do it..like i did..and since then i didnt look back... tongue.gif

To those who have pulled the pads apart in doing this mod and know how they are constructed, would it be feasible to entirely remove the the velour top including the plastic underside part and transplant it onto the inner core foam of the pleathers? With all the pleather material completely removed as well. So you have the velour pads with the inner foam core of the pleathers. The cutout holes wouldn't be needed because the velour top would allow for the damping. Would this in effect achieve the same results as the jergpads?

I'm afraid not. 

 

I've gotten my hands on quite a few pairs of Hifiman velour pads thus far (for personal modding attempts, as well as a few other cases) and have actually seen 2 cases where the velour pads actually have the same memory foam as what's always been used in pleather pads.

 

However, upon listening to those pads, it became apparent that although some aspects were improved with these "mutant" velour pads - namely they sound more forward with a less etched treble due to the different foams - other unfavourable attributes are still retained (lack of weighty lower end, missing lushness in midrange).

 

My guess is that the velour pads are just too over-damped, too much is being lost via free leakage through the velour material.

Jerg, Ryan

 

first of all a million thanks. The Jergpads by Modulor arrived after visiting some continents todaybiggrin.gif. Went straight to Youtube to figure out how to fix the earpads on the 500 (yes there is a one-minute video on this) and straight into music heaven. 

 

First impressions, that bass extension wow ! it hits deeper and hard but always in control. Much better than the regular velours and my J$ pads. It is much airier now and the treble has been softened a tad. The mids are more forward now and on my Mjolnir, I am actually listening to the music at the same volume levels as the LCD 3 (previously I had to turn the knob at 10-11 for 500 as against 9 for the LCD-3). Man, who would have thought Kokomo by the Beach Boys would hit so deep. I can feel Ringo's drumming on Come Together in startling clarity and on and on ........

 

To both of you, for conception and production, thanks again.

Yeah, I had a few pairs of velours that had slightly different foam, but it was mostly just shaped different...same density and feel otherwise.

So has anyone tried cutting the damping holes on the velour instead of the pleathers? If so what are the impressions? I dont want to completely mangle them if it sounds bad.

post #823 of 1702
I think the velours are well damped as-is.

They're only $20 a pair.  Hacking up the Sennheiser HD-600 / 650 ear pads @ $58.00 a pair is a bit more crushing.
