Okay, since you mentioned knock-offs. I was at the Base Exchange at Lackland AFB about a month ago. Keep in mind this is the AF's training base. Their customers are very young. They had all the latest Apple gear, smart phones, tablets, video games, etc. They did not have Skullcandy. They had Bob Marley phones and they had a listening station. They sounded good and have better cool factor.
And as I've mentioned, Radio Shack had there line of Skullcandy on the clearance rack. Maybe the shorts are right. Be careful about falling in love with a stock.
