Their sound is clearly the open, airy, transparent sound of Grados. Yet on one song that has strong bass, they give a palpable vibration to my ear that I have not heard on other Grados. I was surprised that their pads are the S flats as used on the SR60, SR80, and SR125. Headband is brown leather, of quality similar to that of my GS1000e.
I will evetually get around to a more formal comparison to the GH-1 (which I have ordered but don't have) and one of the RS1i, RS1, RS2i, RS2e) choices.
They sound Beautiful!!
Congratulations on the Bushmills, they look great...
I vote for a GH-1 to RS1i comparison, if you're taking votes.
