From reviews, the highest quality Skull candy headphones are considered to be the Skullcandy Navigator and Skull Candy Icon 2 series. The price of the first one ranges between $99 to $100 while the second is from $30. The exact price depends on where you choose to purchase it from.
I personally don't prefer buying Skullcandy products. I went to Vegas last summer and bought $60 headphone. Wen I got back to my hotel room to try them out the audio wouldn't come out. Try something like Beats or Sony hat are higher in quality and at are less likely to not work.
