1) Totally agree and I don't understand. Although a significant portion of their comp is in stock so maybe they need to monetize and diversify occassionally?
2) Good question. Headphones are an accessory like shoes, hats and purses. Different styles and colors plus marketing. It is trendy so Skull needs to keep delivering desirable products. If they lose favor with their core audience they're done. So far so good.
3) Lots of competition. Players will come and go, but am impressed with their focus on a core demographic. Headphones are a relatively new fad and many want a piece of the market. Envisioning Skull as a Nike, Monster Energy or Sony/Playstation whereby they are a top two/three player in their market.
