Bluetooth connection with my Bluetooth headphones?

Bought Victrola V50-200. Instructions indicate can connect external audio device via bluetooth. But, says you need to select V50-200 on device, then provide password. But, they’re headphones, there’s no display on them showing anything to actually select, like say on a computer or smartphone. Am out of luck or am I missing something?

What are?
Where does Audacity figure in this?
