I'm hoping to find a wired headset with more than one button. I realize that I'll probably need to use an app such as headset button controller to make this work. So far i tried an HTC branded headset - without a headset control app running, every button pulls up the voice command app with a short press or re-dials with a long press. With Headset Button Controller installed, HBC detects all three buttons as the center button but if i hold down + or - the volume goes up or down. Very strange. Anyone have any suggestions?
