Sorry for my awkward post description. Didn't know how else to describe it. I have a 27 inch 2020 iMac, which has the headset port on the rear. There are times I want to use headphones (like when my wife is sleeping), other times the iMac's speakers are fine. It's a massive pain to have to swivel the iMac around each time to find the port to stick in the headphones. Is there any sort of device I can buy where I can have the headphones inserted in the back all the time, but just need to toggle something in the front to switch from iMac speakers to headphones? Thanks in advance.
