Can I connect to the amazon fire stick tv with huawei freebuds?

Is it possible to establish a Bluetooth connection to my Amazon fire tv stick

I don't know whether it works, but in the settings there's the item "Device control", under which you can register and control audio devices, and the item "Remote controls and Bluetooth devices", and there the sub-item "Other Bluetooth devices". There you can register and control BT devices. I don't know if that works with your earphones.
