I have my mods specifically set to minimize treble. Im assuming its reflections on the ear side from the pad itself. I went from the drivers pressed up directly to my ears, to small caverns lol.... Im getting my alphas tomorrow, Im assuming silverstone foam on the ear side will help hugely.
I tried that, but what actually goes around the cup was too small out of the box, luckily real leather can stretch rather nicely, with not much worry of tearing like pleather. I stopped at my mom's house and picked up some leather shoe stretch as well which helped. Just a long slow process of pulling on the leather until it was just big enough to yank over the cup. I was careful not to over stretch just in case the Alphas are slightly smaller
Brought them on my roadtrip Im on now (over my MDR-10s or Momentum over-ears), hoping to get a feel for how the pads sound so I can better judge the Open alphas. Buuuut, I forgot my 1/4" to 3.5mm adapter at home. So now Im stuck with no cans at all. The horror.
