It is a very reversible mod.  The only thing that's tricky is retaping the pads back on.

I'll probably be running focus-a when I get it back so don't worry if you mess it up too much.

OK best evidence so far and the most proper test.

Top: Stockish - Jerg mods removed except for holes poked into pads
Bottom: Full Jerg mods

The timescales are not normalized  ;D

Anyhow, there are 3 (4 if you took the grills out) components to what I did to this HE560 unit, the shelf liner material is only 1 of those components. Full reversal would mean removing all the adhesive double-sided tape between the baffles and the underside of the pads, swapping the pads back to stock Focus pads, and keeping the stock grills on.

Hey Marv, how long usually is the duration for a measurement of a channel? I'm wondering if you could do a measurement on yours or TMR's HE560, but with pressure on the cup so that the earpads are significantly depressed, and the drivers are closer to the measurement aperture. Would that be possible?

I just feel as though the 4k hump might be due to something very simple.


The thing is there are only two real differences between Focus and Focus-A pads: your ears are closer to the drivers with Focus-A pads, and the shape/covering of the undersides are different (angular pleather, vs sloped mesh). The internal foam is the same, the outer shell as well. One of those two aforementioned factors has to be the determinant for the 4k hump.
