BlitzWolf BW-BL1 Bluetooth Audio Adapter USB A or Type-C US$15.99 or (~A$23.46) Delivered @ Banggood AU

I found a discount on a USB-A or USB-C transmitter that can enable you to connect Bluetooth headphones to multiple device types. Seems a good little option where the device is lacking bluetooth capability. From an Australian warehouse so delivery time is shorter and GST covered.
