Gah!
I just bought headphones..No, they weren't the most expensive ones..but still
ONE OF THE HEADPHONES DOESNT WORK ALREADY!!!

Should I take them back? or just buy a new pair and save myself the trouble?

I would take them back. usually stores try and save their costumer by compensating any way they can. so you'll probably be able to get new ones if you take them back.
