Using Klipsch image S4(i) with mic, and love them.
As a previous poster said, normal (as in thin) wires but i have had mine for a while without problem.
even got the normal S4.

Planning to buy the klipsch image X5 (no mic) but incredible sound.

Little low treble but thats from the total lack of EQ in the phone.
Never experienced the background noise some posters mentioned on my phone.
but the sound is lightyears away from when you plug in a portable amp but thats probably overkill for most users

budget for around 100 usd and above and you probably wont be unhappy.

Have a look at www.head-fi.org
You will find more info in that place then anywhere else.

Good luck and happy new year!
