= Hifiman HE500 & HE400 Jergpad Mod v2.0 = - Page 3

Alright so after rereading the tutorial a few times and better analyzing the pads themselves, I have a much better understanding of how to do this.

 

I have a couple of questions though. After you cut the holes on the pad, doesn't covering them with the plastic mounting sort of negate that? Since you're covering the holes you cut anyway? Same thing if you decide to glue the dust screen back.

 

And lastly I see no sign of the plastic stopper which sits between the pad and the dust screen. Did you remove that too?

Really cool mod Jerg.  Thanks for the write-up.  I can't wait to give this a try myself.  Just one question though, it seems like you feel the more holes the better, am I right?  If that's the case, couldn't you just enlarge the preexisting holes to allow even more of the inner foam to be exposed?  Maybe it would be a bit easier/allow for more damping. Kind of like this crappy drawing...

Great job, Jerg.. appreciate the detailed guide/pics, too.  I'll try the mod this weekend.  I've got a handy Dremel drill which should make drilling the holes easy and clean.  I'll add pics here, of course.

 

I've got the J$ pads coming too, so I can provide sonic comparisons with them (and the stock velours I'm using now).

I'm going to give this a shot, but I don't like the idea of naked drivers (well, maybe on the road).  Does anyone have any suggestions what material I could use instead that would serve as an effective dust shield but be acoustically transparent?
 

Oh, a question for Jerg .... didn't you say you have a grill mod on your HE500s?  Doesn't this mean my results may not be the same (or even desirable) on my non-grill modded phones?

Is it really necessary to take the dust protection off the pads? Does it really improve the sound? 

 

Does the same apply to the velour pads?

 

 

I've already, very reluctantly, done the grill mod. I don't want to take off another dust protection if i don't need to.

I am very interested in your comparisons. I have some J$ pads installed right now and I think they sound better than the velours. Unfortunately I don't have a second set of pleathers to try this mod but I'm also not willing at least right now to give up the comfort of the J$ pads lol

Just use regular nylon stocking that women wear to fashion a filter. It will be very transparent, like its not even there. Even more transparent than the velour nylon.

Apparently the filters shape the sound considerably. The pleather filter is thicker which bring down the harshness of the highs while the velour nylon is more transparent helps increase the treble energy. Part of the reason the velours give you better detail. After doing the J$ pad mod I think just a regular nylon stocking is best. It's the most transparent..... but different strokes for different folks.

Well, i just did the mod.

 

Had a hard time cutting the pad. It didn't look very pretty.

 

Is it really neccessary to cut all the holes spaced evenly? Because i'm not sure i did that right. Probably screwed it up.

A song that shows off the airiness and syrupy-loungeness simultaneously with Jergpag:

 

 

(I promise I won't post any more links in Jergpad thread)

 

Ever so slight sibilance at one singing portion but I think it's the recording, BUT MORE IMPORTANTLY female vocals have never sounded more directly 'injected' into my ears than now.

 

My modded pleathers are SUPER fragile since my ring-to-pad solution aint great but I find that keeping it in the clamp position when not using them (smushing earpad against earpad instead of just open and apart) is helping.

 

I did a sloppy job (but the best I could with what I had at 2 am) cutting the holes but as long as every section looks relatively abundant with mid, outer, and lower holes in between the 4 ones that are already on there, the sound should be about the same.

I'm  somewhere in between, but the diffs are def there. But I don't think we are talking about more than 2dB anyway between pleather and velour? Anywayz, Jerg get a new amp! I bet the difference will be at least as big as with the mod :P And it is only some 500$

 

Anything to see (cosmetics) when all is assempled?

 

EDIT: Sell your HE-400 and buy an amp :P

ALERT 240p = Very bad audio

 

EDIT: @Jerg What do you think about the stock pleather upper midrange. I seem to be annoyed by too much upper midrange in some recordings. Some kind of 'glare' as you might have mentioned already

I hope more people give this mod a shot, it's quite nice.

I will some time :P
