How to plug 2 headphones into a laptop without a dual headphone jack splitter?

So my laptop has three 3.5 mm jacks, one for headphones,
one for mic and one for speakers.
So I was wondering if I can convert the speaker jack
into a second headphone jack so 2 people can watch a
movie with headphones.
I know there is a dual headphone jack splitter available
but I want to do it without it. Is it possible?

Answer
Can you do it? Maybe. Is it worth the trouble....NO.

You would have to remove the main circuit board from your computer. Then, depending on how the traces are routed to the speaker jack, you would have to cut them and then jumper over from the headphone jack.

Now, if the traces to the speaker jack are on an internal layer of the printed circuit board, you'll have to remove the speaker jack from the board, drill out the mounting holes to clear the via connections, glue the jack back in place, and then add your wiring jumpers. Oh yeah, there's a specialized drill bit that you need to use in order to not short internal layers of the PCB together.

Really...it's that big of a hassle to use a headphone splitter?

If you have a headphone jack splitter, will speakers and headphones work at the same time?

I need to be able to use speakers and headphones simultaneously in my macbook pro. If i get a headphone jack splitter, will my music play through the headphones and the speakers or only one of them?

Answer
It will play through both.
