Thanks Pianist, for you excellent comparison...

Anyway, I've gotten chance to listen both to the Klipsch S4is and D-Jays, and so far I really like S4is, they've got great bass, the high does not disappoint, definitely a keeper. I like a more than my ADDIEMs, even though, there not so bad either. My first reaction really was "WOW" when I put these thing in my ears... so Thanks Sanctoman, good advice, and for the price I paid for them with black friday, of € 74 euro including shipping from the Apple Store, I cannot complain.

Because of the all the bad comments and reviews about ear piercing sibilance and other stuff about the S4's, I also ordered a pair of d-jays from eBay, which I payed about €65 euros for including shipping. Well, I put these things my I was a bit disappointed... I expected more from jays. They're quite well balanced, have a wider soundstage then the ADDIEMS, has good mids, decent highs and bass, but I kind of feels like it's cut off somehow. Thus, I regret buying em, and thank god, the shipper has a return policy so I can my cash back... btw, I'm not saying all jays suck, I just don't like this pair. If I paid maybe 30 euros for them I wouldn't really care, but for €65 I think I can be a bit more picky..

I can better spend that money on a pair of new cans, my Akg's need replacement
