How to block others from connecting to Wyze Headset

I don’t know how, but I had a neighbors music playlist come over my Wyze Bluetooth headset. The only way I could stop was to power down my Windows PC and headset. The headphones were paired to my PC at the time.

How do I keep others from pairing to my headphones?

I checked the Wyze app on my Android phone but don’t see anything.

Thanks in advance.
