Help with best buy headphones&warranty!!?

Okay so i have a pair of skull candy ink'd headphones that i bought from best buy, i also got warranty on them. This is the second time they've broken, and im about to get another pair. (thank god for warranty) and the pair of headphones i had before the Ink'd that i Absolutely LOVED were the Skull candy Titans. I wanted to buy those but didn't have enough money at the time. And now i want to see if i can just get the new pair of skull candy ink'd ones (because they broke again), but return them and pay the difference to buy the Titans. Is that possible at Best Buy??? If you guys can help me that would be greatly appreciated!!! please help!
