I have both the EX-70's and the HP-vx100's.
Speaking about sound quality, the 70's have way too much bass emphasis, and are lacking in the highs. They almost sound muffled. This is without the mods that are described in detail here on Head-Fi and evidently result in a better overall sound quality. The vx100's have good bass and good highs. The detail is better over the whole sound range.
Fit: the 70's come with 3 sets of "ear fittings," S, M, L -- I had trouble getting a good fit with any of them, although the Large works best, and the buds stay put. The vx100's come with only one size fitting,of which you get two pair. They are a little larger than the 70 large. The 100's fit me much better than the 70's, and are more comfortable.
Isolation: both are fair, and are similar. I prefer the vx100's, and use them when I'm out and want some isolation from ambient noise, but not total isolation like my Ety 4S provides.
The Plug by Koss is a similar type of earphone--goes into the ear canal, deeper actually than the Sony or Aiwa.

--They are different types of earphones. I do agree, though, that they sound better.
