Audio output quick-switching software

[gevo12321]

I want to always have my headphones plugged into my PC along with my speakers. Is there any software(widget or something) that would allow me to switch between audio outputs with a click of a mouse? Maybe with a pre-programmed hotkey? I know I can go into the sound settings and switch it from there, but I want it to be super quick.

I use a physical switch which I put next to my monitor for switching between headphones and speakers. $30.
