Beats headphones not connecting via bluetooth

I bought the Slate mesh series from Costco today and noticed that the Bluetooth doesn't work at all. I tried to connect so many times, but nothing. I checked the computer, and it shows Bluetooth. What's going on here? Why does it say on the box that it comes with it, but then it doesn't work? It came with the antenna for WIFI, but do I need to buy a USB or something to get the Bluetooth to work? It says it has a 5.1 Bluetooth in the specs
