I most say, it seems unprofessional that hifiman has done nothing to proper dampen their 'phones with their pleathers. 

I see what you mean by ringing even though I could not identify it myself, but after all I am not as experienced yet biggrin.gif. I especially find it to be present with acustic guitars with the metal strings. It seems kinda sharp and uncontrolled. In some songs it seems to cause listening fatigue.

 

Also, Jerg, what did you do with the foam ring inside the pads?

Yep, midrange ringing is easily identified with intimately recorded guitar or piano, where there is a heart-wrenching "glare" at the fortissimo segments of the tracks. Unmodded pleathers have that issue, simply due to lack of damping (the only damping are the four tiny holes, which is not even close to enough).

 

The foam insert? I cursed at it, stomped it, and threw it into a burning pile of trash. Seriously they offer nothing but badness to the comfort and sound quality of the pleathers, modded or unmodded.

But how did you get them out?

Just grab it and pull it out. You can even do it while the pleathers are attached to the headphones.

A pair of pliers and a blowtorch, of course.

Funny how the bass suddenly loosened a bit and the sound became more fluid and perhaps even more effortless. Almost a bit more laid back. And that is only from removing that foam thingies. A small improvement.

The mod will tighten the bass, right? I'm not sure if I like the slightly more boomyness without the foam rings. It does seem more natural, though.

The foam ring is a hack so that Hifiman doesnt get as many complaints about users having their ears touch the hard driver.

 

IMO the increased clamp and hardening of the pad due to the foam ring propping everything up is much worse for comfort than without the rings though. The pleathers actually use a pretty amazing memory foam that seems to be heat-activated and become REALLY soft and nice after a few minutes of use, and the foam ring nullifies all the acoustic and comfort aspects of that foam by compressing it up.

 

Yes, the bass tightens drastically with my mod. HE500 bass quality goes from a 7/10 with the stock pleathers, to a 9.5/10 with the jergpad mod. On that arbitrary scale, I would rate velour bass to be 7.5/10 (a bit too thin and lacking in weight, is quite tight and punchy though), J$ beyer bass to be 9.75/10 (marginally better than jergpad, but it's negligible, especially as jergpad improves every other aspect of sound much more), and vintage HFM velours a 5/10 (confused and way too anemic + lacking impact).

I'd actually say that the bass, isolated from the rest of the freq response, is a BIT better with the foam ring, but still there is something less natural about it.

Going to try the mod when I get some extra pleathers... My mom won't let me cut my pads because she has payed half of the 'phone :S

I can just get the mental imagery of you and your mom tug-of-warring the pleather pads lol.

I wouldn't call it mutilation. Sure there is a lot of cutting involved but it is all for the betterment of the pads, kinda like life-saving surgeries.

I will by some pads for sure. They cost almost the double (35$) for me to get, and it better be worth it :O

Better go to bed after this album - since its 3:30 am here. Maybe after this album rolleyes.gif

True. When you're jabbing the back of the earpad and not sure what the end result is gonna be sonically, it can feel a bit like mutilation. But agree.

I thoughtfully snipped out all the holes with swift, fine strokes of my sharp scissors, a schematic blueprint right beside me. It did not feel like mutilation at any point. But I suppose not everyone tries to maximize precision and control with modding.
