I have a set of s-Jays but I'm not voting as I've not heard the others and don't have a lot of experience with IEMS.
The S-Jays have a good soundstage for IEMS and do very well given a good source. Bass is tight and punchy. Isolation is very good with the foam pads supplied. They don't sound quite as natural as my full sized Goldring NS1000s but they're more detailed than my Creative Aurvana Lives! They do seem to benefit a lot from a good source and a portable amp (I use a Fiio e5). Was pleasantly about how good they sounded with my Xonar D2 and Sony receiver - it actually prompted me to have a clear out of some of my low to mid-end full sized phones (that and the effect the e5 had on my NS1000s). Overall very pleased with them.
