Plz help or send me to someone who can...

Hi, I have a question about having two headphones on one computer...
You see, I was wondering if my sister and I could watch a movie on my computer together, which would mean that she would need her own set of headphones...
So this is the situation, I have a usb headphone...(a headphone who connects through an usb cord... and i have another that is able to use a 3.5mm jack...
I was wondering if there was any way that we could somehow get them to both work, at the same time, so that we could watch the movie...
I dont know if im in the right forum...but I hope you can help...

 

Why couldn't you get a Y-jack, give up using the USB headphones, while you are sharing the movie, and add another set of ear buds or headphones. Then you both could listen.

 

i dont entirely understand?
I am able to plug them both into the computer, i just cant get them both to work...
