Can't help you on price, but maybe I can keep you on track
I bought a pair of S4i recently (essentially the same set as the S4 but with iPhone controls) and really do think they are quality. I also own a pair of Sennheiser CX-95 which I tested back to back against a pair of Shure (can't remember the model number but they were similarly priced before discounts) prior to choosing them.
I can quite honestly say the Klipsch are better than the Sennheisers. They fit my ears more comfortably with the oval tips and need less readjusting over extended listening. The treble seems better resolved and they give out a little more bass too. Midrange punch and definition is about the same. They are however quite revealing compared to the CX-95 so will show up any poorly encoded mp3s.
I can't think of any other earphone I'd look at for the price.
