After some learning:
"Speaker Breakout" is a Apple Pro Speaker connector that Apple invented and used in its G4 Series Mac.
Apple Pro Speaker connector is like the smaller 2.5mm TSR (Tip=Sleeve-Ring) audio jack, but with addition circular metallic base.

- preowned, clean condition and tested working
- the sale is for this usb audio device unit and a power adaptor
