Default Three buttons headset?

Hi all!
I tried a three buttons headset (from my HTC Desire Z) with Player Pro, but only the play button works, while the back and forward buttons to skip tracks don't work, or, better, they work as the play button.
I also tried a setting to skip tracks long pressing the play button or pressing it 2-3 times, but neither this worked.
I tried both in the stock rom and in CyanogenMod 11, and the behaviour is the same.

Actually, I'm inclined to think that three buttons headsets are not compatible with Droid 4.

Anyone can confirm this or suggest me a working three buttons headest?

Thanks in advance!
