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).
