@ Brendan Phillips > Sorry to hear about that. You won't be able to get the info on specific parts or part prices here. But you should contact technical support in your region. The links are in the top left. :)
Best of luck getting them fixed, and down the road for your next pair, look into the HDJ-2000's! you can twist them and bend them in ways you should never even think about doing to any other pair of headphones! Truly a masterpiece and you will probably never buy a different pair of headphones again!
