I just had Samsung's AARM040EBECSTD headphones for 7 US$ and as you can see in picture it has mic + button + volume. So you can use for Play/Pause, Next track (double click with newest SGS fws) and volume. PowerAMP supports Previous track with triple click too.
The good side is I have tested and it works with any standard headphone with 3.5 mm plug. Mine is Koss Porta Pro and works perfectly. It is great when you go out during winter. One controller and most of the features are delivered.
Hi all! I just bought 2 of these these earphones on ebay, and they don't seem to be working properly on my (and another) i9001. The sound is really low, but when I press the answer button, sound seems to be ok. I really just wanted some earphones with volume control...maybe I bought some cheep chines knockoff, I mean i9001 is not so different from i9000 and I doubt that is a problem
Mine look like this http://i40.tinypic.com/142d3d1.jpg
Samsung changed the pinout of their TRRS from Nokia to Apple layout. Consequently, the ground and mic pins got swapped. The answer button shorts the mic pin with the ground pin, which is why the earphone audio level is normal when you do so. I think if you swap the M+ and M- conductors around on the right hand side of the PCB in the photo, it'll work. To be safe, you probably ought to swap the red and black conductors of the condenser mic around on the left hand side of the PCB too.
I've not tried this, so do so at your own risk.
