Maybe one day I'll get to have a listen... No doubt that the HE-400 measurements do not speak for the HE-500.

I thought you guys were adding another step by cutting more holes into the pleather.

Jerg, have you experimented with using socks to go over the pleather pads instead of the velour (got the idea from Kotaku's Grado mod)? I've been experimenting with it a bit using black dress socks and believe I'm getting good results from it. I have not yet figured out how to keep them on more permanently without sewing them.

post #964 of 1671

Socks turned out to be too much of a PITA to work with in the end, and I had no way to attach them permanently (I can't sew). Other than that, the bit of experimenting I did with them had good results. Socks offered a lot of the same changes the velour layer did but with less of an edge to it...more relaxed. I liked it. I'm using the velour layer right now, adhered with some "permanent" (not really) glue stick thing. Works well enough for now.

 

I've done every part of the mod except the sub-bass adhesion mod. Really liking what I'm hearing! I also replaced the grill with something more transparent.

Hmm, dress sock material could be good but they may be too tight and I can imagine it being a PITA.  Did you use thicker or thinner style?  I do suspect it works best on the smaller style foam pads like on Grados as I've seen it before.  I was thinking another alternative material could be some sort of microfiber like what appears to be on the new style Beyer pads, but I have yet to sample anything like that.

post #966 of 1671

I tried both. The thinner material worked best overall. I bet you could sew it on and use it that way, but it has a tendency to slip off easily when rolled on.

I updated the first post to the newest Jergpad tutorial that Modulor has been slaving over for the past several weeks.

 

The core modding concepts are same or similar to v2.0, just more optimized, plus there is one additional easy modding step for those making the pads for HE500s. Hence I think calling it v2.5 is appropriate.

 

Thanks Modulor!

Nice. Ordered some last week. Can't wait to try them out. I would love to see the frequency measurements for the HE-400 when they come out.

Is the outer mod (for "quelling the resonance in the mids") now approved? Or are you still considering this?

 
And was there an earlier post regarding back and front vent mods? So those rectangular foam tabs in both the front and rear of the pads in line with the direction of your face?

The foam pieces should only be on one corner of the pad and they should be facing backward as to angle the pad. Hence the "rear vent".

It's approved for HE500 owners. HE400s don't have the issue so it's useless for those guys to mod it in.

I believe there was some talk of using the vents facing forward with some interesting results, perhaps jerg can elaborate.  Primarily they are to go in the back for better fitment.

Had already performed some mods on my pads but after seeing the extra holes in 2.5 I had to take out my pads as I had to add some more holes!

 

 

 

Did some improv by using some double sided post tape to raise the pads and make them stay.

 

Now for a listen...

Did you get your Hifimans painted Netforce?
