the UE's are amazing, I look like a bit of a tool, but I did the flipsy swap cable earpiece thing and i look like a less of a tool, but the sound is great.
They do have some comfort issues, but they sound much better than the UM1s and ER6is IMHO. The ER6is I use at work, wrapped around the ear to combat its horrible microphonics. The UM1s are really comfortable and light as well.
but yeah, the super fis i bought off a head-fier for the same price as radioshack (just under), so its def worth it, even if you buy it for $50 i think is what radioshack have it as.
and it looks sexy! i wish they had a red 160gb ipod, then my phone, earphones and ipod would match. in the process of looking for a cheap red mp3 player jus so i can be all red lol!
