PAD FELT MOD:

 

Introduction

 

I have already talked a bit about using different materials inserted inside Hifiman pleather (or velour) pads to further smoothen HE-4's treble response... And I really enjoyed the way rug pad worked with Sennheiser HD800 - it lessened resonances inside cup chamber without decreasing airiness and imaging too much. See the physical difference between it and typical 2mm felt:

 

 

Rug pad was nice with HD800... But HE-4 may need something more dense. Therefore I decided to try this approach with the felt itself... I wanted to achieve smoothening without decreasing imaging, sense of openness and level of airiness too much (which may be the case with a non-perforated felt).

 

 

How to do it?

 

Here is an image how it can look like (above is a non-perforated, below is a perforated version):

 

 

Insert one circle inside OR underneath each pad. Inside means INSIDE the pads - it will hold there by friction. Underneath means in between pad and driver - it will hold there because it won't have a chance to move at all.

 

 

How does it effect sound?

 

I must say that it works as expected... Slightly decreased air as well as smoother treble response but the quality of imaging remained the same - or even very slightly improved due to less airy/more black background. Slightly cavernous timbre of the pleather pads is fixed. Sense of openness is a bit decreased, perceived soundstage width also slightly (but you cannot have everything). This mod works best IMHO when inserted underneath the pads (not inside the pads as I was using the felt before) but you could always try to insert it inside as well for slightly different effect on the overall sound. Description of slight tonal improvements follows...

 

"Especially focusing on both male and female vocals, I found that while both pleather and velour pads gives similarly nice male vocals (a bit different but similarly fine), female vocals are significantly less natural with velours (more sibilance, less natural tonality). With pleather pads, I would say that both male and female vocals were sufficiently natural but the felt (insterted inside/underneath the pads) improved on that appreciably - it basically made both male and female vocals a bit more full and somewhat "shifted" sibilance in a way that it's pronounced in a more natural way (there is still some slight sibilance but now more authentic/natural-sounding)."

 

I would like to encourage anyone to experiment a bit with the mod - try to use perforated or non-perforated felt, insert it inside or underneath the pleather pads - to find the best configuration. And, in the end, it may happen you would rather prefer to use the pads alone, with no felt.

Just wrote them. hoping to do a balanced mod on my shure 840s, since i have 2 balanced hifiman cables, figured id just try and use those connections. Not that i am a huge fan of them, but theyre a solid sturdy connection.

And they are very easy to work with! Much much much much much easier than HD800 connectors for example... Even I could do the soldering job with them! :-)

good because i am not a very good solder tech...

FYI my fellow he4 enthusiasts, just received an email back from Hifiman regarding trying to get the female smcs. theyre not getting that i want the cup side...but anyways..i also asked about the new pads, And they said, no release date decided as of yet, but VERY soon. So lets cross our fingers. I am ordering alcantara pads for mine for now though since theyll work on my 840s anyways

hmm I have some interesting news you guyz... I think my HE 4 and Beyer Pads have fully broken in. In about the last week or so, I'm noticeing a touch more sub bass than before... might be the wood cups breaking in as well, as the wood should add a touch more bass due to the resonace... either way... it's sounds a smidge better than before... at least bass wise, I play a lot A LOT of pvp mmos and I have about 15 tracks I listen to while doing that... and I have noticed more sub bass recently than previously

Nice!!! And I do know that the 400i and 560 pads will be different. The 400i, from all the pics, have an angled all-velour pads where as the 560 has the Hifiman Jerg.

so whos trying em on their HE 4 

post #2368 of 3124

im waiting on my alcantara pads to get here, which im keeping either way for my shure 840s. Then if the new hifimans work, ill consider them, but honestly, i may go back to the alpha pads and try to figure out a way for them to work. I miss the hell out of those ear pillows.

awesome, i cant wait to try the alcantaras on my shures and the he4, to bad my hifiman male connectors are scheduled to deliver within the month, but itll be cool to have my headphones have matching connectors, and ill have extra in case my he4s go bad for whatever reason.
