I know you were trying to eliminate biases and expectancies, but you might have eliminated a lot of actual useful information along the way.


Maybe if you listen to your music in mono then maybe you can use this method for a very raw and broad impression.

Nope, mono is no-go, I have tried. You can't compare anything while only listening with one ear.

Listening with both pads, I can say that I am pleasently surprised by the sound stage, and the cupped in feeling seem to be gone or almost gone. I think I hear it with vocals of osme artists, but it might as well be the recording.

As of now, I cannot really comment on the sound signature.

Hey jerg, i read on a different thread someone is modding the velours pads for the he500..Ru going to try that too?biggrin.gif

Well I am going to mod the velours by covering them in leather. I already have the leather in the right pieces.

 

Now my so needs to stitch these together :p

 

Not sure about damping, should i add extra holes? Again what was the benefit of the extra holes exactly?

The benefit is appropriate dampening :P

I don't know how you are going to do it, but some dampening would be good.

What is the benefit to the sound exactly? I noticed that the mids became more apparent, when I added the holes.

But too much holes makes the sound too bright.

 

Jerg?

I'm pretty sure he meant playing a mono signal to both ears.

No no, i actually meant with one ear. What I tried to say was, if you're going to compare stuff with just one ear, atleast turn the sound to mono.

 

Comparing pads with on ear is possible, just to get the basic idea. But that's about it.

 

EDIT: And ofcourse pan between the left and right ear!

Ah, well I'd still recommend playing a mono signal just to remove the stereo differences in the recording.

Mono and 2 different pairs just doesn't work. I found it to work, when I focused on specific sounds/instruments coming solely from 1 of the stereo channels, then switching the channels in foobar and play the same over again. I don't really know if it was a good idea to do so, but it seemed I could hear differences, even though I could not judge whether it sounded better.

I cannot do for now, as I don't the velours at the moment. Sure I can make a comparison in a week or two. But you must know, that I was a pleather lover from the beginning, despite the cupped in sound.

 

 

 

Know I have spent some time comparing the stock pleathers and jergs with venting mod. The jergs win hands down when it comes to sound stage. Seemingly a bit more focused but still natural.

The HE-500 seems to be more refined now, even though I found it very refined beforehand. 50% because of the sound stage and 50% because of the sound sig.

 

Just heard a couple of older recordings which is kinda fading in nature. The sound stage sounded unnaturally enlarged with the pleathers, like if they were trying to sound intimate with a record that wasn't supposed to sound intimate. The same songs sounded totally natural with the Jergs. I might go more in details in a couple of days when I have had some more time comparing. Maybe I'll also make a comparison with the velours and the J$

Jerg?

I described the need of proper earpad damping in the first post of the thread. (For those of you who keep calling it dampening, that's the wrong word biggrin.gif)

 

 

Stock pleathers are severely underdamped.

 

Think of the soundwaves produced by the driver going to your ears, then a lot of it naturally gets bounced back because it did not project and enter the ear canal, after that you NEED proper damping somewhere in the earpad opening to take that excess soundwave energy away in order for the maximum clarity in the music.

 

With underdamping, that excess energy just bounces around in the earpad opening and muddles up the sound, causing you to perceive less resolution, less "openness", less clear imaging / staging, and overall less transparency.

 

If that excess energy finds a way to turn into ringing (which it often does) then you'd also get undesirable changes in sound signature, e.g. wonky midrange / cupped feeling etc.

 

 

I never bothered with velour pads because tonally it sounded too bright and thin (due to a combination of the fabric, the foam cushions, and the depth), and modding it won't get it that much better either. IMO it is overdamped, and also its shape and types of materials make it unfit for giving Hifimans a good balanced sound. Modding can't help with that.

Thanks Jerg :)

 

Well when I cover up all the velour with leather it will have close to zero damping.

I was going to use the modded velour pads for my closed headphones, but they offer no isolation at all.

 

The velours are deeper than the pleathers, and a bit stiffer. When I cover it with leather, and cut some extra damping holes, the sound should come pretty close to the jergs.

The leather has been cut, now i just need my girlfriend to do the sewing!

 

So this is just a fun experiment :)
