It's once again the season for giving, and what better way to celebrate than a chance to get your hands on some cool prizes from your pals here at Gadling.

We kicked things off yesterday with a chance at winning a full tuition from Matador U. Today's prize is for a pair of Able Planet Clear Harmony noise canceling headphones. Retail price is $299.99, but one lucky winner will get them for free.
