    I bought these MonoPrice headphones: http://www.monoprice.com/product?p_id=13191

    They work fine, except I didn't realize that they don't come with a cable to split the stereo output and microphone input, which I need for my PC in order for the microphone to work. Currently, I've plugged it into my PC's headphone jack, and just can't use the microphone until I get a splitter.

    However, I noticed that the in-line control button isn't adjusting the volume, so they're set at their 100% internal value and just 20% volume on my PC is extremely loud. When I plug them into my Android phone which has a combined headphone/microphone port, the in-line control works and acts as a play/pause button.

    So my question is: Do I need the splitter for the in-line volume control to work as well on my PC? If it would, I'll definitely get a splitter so that I can use it and the microphone, but if not I'll probably return the headphones.

    I don't believe the inline control will work unless the source can understand the control signal that is generated by you pressing the button, and then respond to that signal. A smartphone knows, but most PCs probably don't.

    So how do the volume control buttons on my keyboard work?

    You just push the one labelled (-) for quieter and (+) for louder :D

    Obviously. ;) But I don't understand why headphones can't control the volume on a PC, if a keyboard can?

    The PC is designed to work with the keyboard. It is not designed to work with your headphones.

    The ball on the end of the chain is the earth ground.

    I knew I've seen that picture before, my metaphorical wife on her cell phone.
