This is something you probably won't fully appreciate until you've had one for a while and then lose it. You may not need a headphone extension cord with an inline volume control. But once you get used to having one, you'll find the convenience and functionality are habit forming. The one I lost was in daily use for 3 or 4 years and continued to work well.
This is a surprisingly useful gadget, as it serves as an extension cord and volume control. The extension cord aspect adds about 3 feet to your headphone, which gives me a lot more room to move when I am listening to music on my computer. The volume control is handy when using a portable player because you can change the volume without jostling the player.
