Yes, please post back after testing.I have been quite pleased with the Dekoni platinum series earpads (link) for the last few years, providing better bass definition (not 'volume' of) and comfort / isolation. Those are the only from Dekoni that fit the HP-100 & 150's aside from their other hybrids with dimples and velour ones which are all worse and brighter absorbing more bass. Alas they are wearing out, so actually yesterday I ordered some sheepskin leather earpads from Brainwavz (link). Unless you're in a hurry (?), I'd wait for me to test these out and give a shout back on the result.
Looking like those Sheepskin leather ear pads are on sale
