I have a pair of the Klipsch s4i's but I hate it how tangled they get.
They fixed that with the newer version.
I've used Klipsch s4's, TF10s, davis tributes, etymotic hf5 and some others, my favorite, by far are still my Yamaha EPH-100. I'm in the market for something that sounds as good but with audio controls and a mic. I might go back to etymotics, but I'm not sure how the controls work with Android.
Anyway, I can't recommend the Yamaha's enough!
