Yes I got the S2. And yes I got the fxt90. While I do like the fxt, the fact is that it is a fun phone, and can never make it to the top. Not the same with the s2.
Now they had about 20 hrs of run-in, and a summary of it's sound is like: very detailed (not monstrously so), very balanced with a very linear bass lift, maybe a very slight dip in the mid bass (so no veil whatsoever even with its impactful bass) and a tiny lift in the presence range, bringing the vocals a tiny bit more forward than the clinical sounding monitors, and well extended and controlled highs. Pretty quick and snappy in response, not overly so. Soundstage is above average, not spectacular but still very creditable.
What made me think it's so perfect (new toy bias beware) is that besides it's pretty much all fulfilling sound, it also comes with wonderful craftsmanship (very classy finish, copper alloy enclosure, stylish dual color cable and nice and strong looking plug) top rate comfort and wearing stability, great style (the gold accents are subtle yet noticeable i.e. Just the right amount of bling. Glossy finish very well done), the perfect accessories (a simple yet beautiful and very practical case, and the right amount of nicely crafted tips), and a fit-all button for everyone who'd accept that handiness means something more than the last bit of SQ, if any, and a very friendly price. Isolation is not the best but I get no problem using them in the subway. And the price o the price.......it certainly made the ie800 price tag looks laughable.
YMMV, but it is the first time I feel like I've found the final piece to my ultraportable rig.
