So far I have found the yellow foam sleeves to provide the best sound and comfort for me, but I am curious about the Comply ones referred to in a prior post above as well as the new black foam sleeves which come from Shure I assume.

Would also like to hear some more comments concerning how/why/whether the Complys are better than the yellow foam sleeves.

Also, so far I haven't been able to find a source for the black foam sleeves, which sound good just for the color alone, but I wonder if they are improved in some other way beyond merely the color. I looked for them but did not see them for sale on Shure's site.
