Shure SE530 review

I am in process of upgrading my existing shure e4c headphone and looking for advice on which on to choose, I read a lot of good reviews about SE530 but can't remember if WHHS&V had published any review in the past, also how does these compare to Klipsch headphones and does the extra 50 euro over Klipsch worth the investment.

I will be using these with my iphone 3G and on PC which has got Creative X-Fi xtreme music card, most of my music is either 320 bit mp3 or FLAC & Apple Lossless. I like all kind of music specially with heavy beats and vocals, so good bass is  must.
