HF2 = Play, pause, next, previous (with the random clicks you do to the single button).
HF3 = Play, pause, next, previous (with the random clicks you do to the center button) along with volume control (up and down buttons).
If your iPod/iPhone has voice control (shuffle, Touch, etc) you can press and hold the center (or single) button to activate it.
Hope this helps :)
