I've done backvent mod and the core mod (cutting holes)

And I've put some foam wrapped in cut leather from an old headphone bag to make the headband nicer to wear.

 

Impressions: (better comfort ofc) and sound-wise I like the more airy sound and a bit more bass.

Will do the other steps later for sure!

Great mod Jerg. I used it for the HE-400 and it just sounds like it's a whole different league.

 

A few tips to someone doing this:

- If you're using double sided tape for the velour top, It's easier if you put the double sided tape onto the pleather and work on the velour.

- If you bought the "Scotch Permanent double sided tape", for the "pad-cup adhesion 'sub-bass mod' use two layers. The cups don't stick onto the headphones with one layer.

 

Take your time, and have fun.

Hi Jerg,

 

If you use the Beyer J$ pad so as pleather pad so that you can skip cutting the pleather pad, and still do other steps, will this work as well?

Thank you.

No, 100% no. The point of using the pleather pads is because it has a very specific shape and materials that give a great tonal balance, all the steps of this mod are just to enhance the pleathers and eliminate issues that they have, with a central goal of preserving its voicing.

got my gf doing this for me and it's looking goood.

 

I have one question though. For the velour top part, wouldn't the tape underneath affect the sound in some ways? I mean, it's like paper between your ears and the headphones...

The tape I used is a very thin adhesive film, so its pretty much equivalent to smearing some glue on the pleather. Shouldn't have any discernible effect on the sound; the main effect is the velours which actually break the seal of the pleathers.

Right okay. By the way, just did the part 1 and my impression of the sound difference is that the sound comming out sounds definitely thicker, most likely because of flattened frequency graph. Interesting thing is that when I EQed the sound to flat, I did reach flatness (I think so anyways haha) but the sound was much thinner. I appreciate that difference.

 

Will give more impressions when I've finished the mod in few days.

 

EDIT: Percieved detail level has increased in the flattened area as well.

 

EDIT 2: Part 2 definitely improves the imaging ability as well. A lot of improvements are suttle but enough to make the HE-400s much more enjoyable imo.

Hey Jerg, I've almost finished part 1 of the mod but just wondering if you can skip parts 2 & 3 and do part 4 with the same subbass extension result?

Oh yeah definitely.

 

IMO Part II synergizes very well with Part VI (the added openness and central focus due to Part II complements the added bass extension of Part VI), but sure you can opt to just do Part VI.

 

Part III is definitely the most jarring part of the whole procedure so I don't blame you for wanting to skip it, however I have to say Part III is on par in terms of imaging improvement as the core mod itself, it's a huge deal.

I may go the whole way - first I'll just see how part 1 sounds. I figure if there is a definite improvement then that'll be enough to motivate me to attempt the other parts of the mod. Thanks for your input.

Jerg, I've got an interesting question for you. can you blind test differentiate jerg pad HE400 and HE500 velour?

Well blind test would be out of the question since HE400 is significantly lighter than HE500 lol.

 

But if you are asking if the two are close to identical-sounding, I'd probably say no. Jergpad HE400 has a relatively tamed treble and lifted upper midrange relative to before, but it's still quite different from HE500 with any pads. The claim I made really meant that Jergpad HE400 got close to the level of fidelity and enjoyment to the velour HE500s at least to my ears.

Thanks for the reply.

 

So, technically, what is the difference between a HE400 w jergpads VS HE500 w velours then in your opinion? I'm asking this as a person who was once interested in upgrading to the HE500s but after trying out the jergpad mod, not so interested anymore.

Jergpad HE400's are still a bit leaner and meaner in the upper end compared to velour HE500s.

How about detail level, soundstage, imaging, treble, bass extention?
