StPAD

HM5
Thickness: 3cm
Inner size: 7cm, 5cm
impression about StPAD:
Because the thickness only 1.5cm, I'm afraid this earpads is not comfortable as stock, but I will add foam or toilet tissue if not comfortable.
From the website (
http://www.yaxi.jp/product-gallery/stpad-for-studio-headphone-dx/), they said the earpads are made from protein leather and high density urethane foam. StPAD really denser than stock pads, have better quality than M50x pads, sorry can't remember precisely of M50x limited edition pads (but it's better than standard M50x).
My earpads broken 1 month ago, so I can't directly comparing with StPAD.
HM5: bigger soundstage, reduced midbass impact and have sibilance. And must increasing volume from your source (I can't recommended it for MSR7). Try to add few layers of very thin clothes to reduce sibilance. Big plus of HM5 pads is really comfortable.
StPAD: I think almost everything is sounds same (
I really like it). but I feel something different
After 3 hours:
I wonder why with only 1.5cm thickness, compared to stock pads 2cm, but I'm prefer StPAD than original earpads. Maybe my ears pressed properly. Because with stock earpads, sometimes my antihelix is hurt
