Dog chewed up my son's Skullcandy buds so we stopped in Best Buy for new ones. Slim selection so I asked the clerk what's up. He said they're by far the most popular and get sold out. So we went to Target and got the same story. And I can assure you they weren't marked down as they were $5 more than I paid for the set last month. And they said these products will fly off the shelf during the holidays. Sounded positive to me.
Sounds like they may have a supply-chain problem. Too bad they're not in Walmart. Every time a set of KOSS headphones crosses the scanner it triggers an order and more are loaded on the truck and on their way to the store.
