Headset Control Box

I have a Sades USB headset that I got from Amazon for teleconferencing. This headset has a control panel that gives easy access to volume control plus mute speakers and microphone buttons.

The downside of this is that these buttons wrap around the side of the control, and the control hangs on the cord. Seems like anytime I move while wearing this headset, the control bumps into the arm of the chair or the edge of the desk, and will mute the mic or speakers without me realizing it. Or run the volume all the way down, or all the way up.

So this is a design for a box to encase the control in. The buttons cannot be activated by bumping in from the sides, and there are holes on the top where you have to mean to press the button - you can't accidentally hit these buttons anymore.
