I would occasionally like to use (wired) headphones, but 90% of the time I am fine with just hearing the audio that comes out of the crappy monitor speakers. If I plug the 3.5mm cable into the monitor's headphone jack (even without headphones attached), then no audio will come out of the speaker anymore.

It is really cumbersome to plug and unplug the cable from the monitor, because I have to pull my desk away from the wall and bend upside down to even be able to see the port where I am supposed to plug it in.

Is there some simple solution to this problem, or am I just stuck using one or the other? I have a small desk and don't really have room for external speakers.
