Uncompensated response with various holes sizes for the mod shows same trend as on solderdude's report.

I think that you are mixing up mods.

- 1 mod is about cutting out a hole in the front protective foam (or so i ve read for hd650), i dont believe in it, it seems to measure the same.
...
Thats sad.

Thanks - I'm beside myself, I just don't get it w.. is wrong with this guy, and is he talking about. The HD650 quarter mod is been around for over a decade, however I would not do it. Easier to use ladies stockings instead of foam to lower attenuation of upper mids and high frequencies, but not might be enough if one finds them too dark (vailed). As for the removal of the rear foam on 58X, I didn't notice enough of difference to remove it. The SolderDude mod is super effective and I'm very happy how they turned out. If I be able to get AKG K240 foam pads, I will try the other mod version, but I'm afraid they might be too bass light with it. My DT880-600 spend most of the time on the shelf for over a year ever since I got 58Xs.

HD650 'foam in front of driver mod' is also included in this pdf. (page 23 to 26)
The KISS mod (removal of the rear damping foam on the driver) is not included in the old pdf but does the exact opposite of what has been achieved with the HD58X mod. the KISS mod increases the warmth/midbass hump and increases the chance of dust getting into the airgap of the driver.
it's a silly mod.

"10OFF discount code isn’t valid for the items in your cart"
Probably because they are already discounted.
