Can I plug one pair of earbuds in the output jack, and another pair in the input jack as a mic?

I tried it before, and it worked then, but for some reason it won't work anymore. I've tried many different settings, but I can't get it to work. I'm stuck.
 
Unless the port is a dual one (input/output) there would be no way for headphones or earbuds to work in it. If it is for microphone only, then it would be input only, meaning no output so no way to hear through it. I would check it to find out if it is is in deed a dual one or not. The icon/symbol by the port should let you know or you can look up the laptop's specs.
