I have a hackintosh, and as such, it does not have much to connect audio to. So I bought a USB audio DAC whatever it stands for which successfully (god, I low the English word sucks fully) died on me. So I, with no need of 3kW sound but 0.3W thought was ok, connected the motherboard from the above device as an amplifier. And it did work for a while. And I was able to connect to it via bluetooth. Sadly because it was bearbones, something touched something and it first started to make a sad buzzy noise and then stopped altogether. I still have the sad battery with its board attached to it. Laying on my desk along with gold Rolex watch from 1950s. At least one of them is still salvageable.
