This is a set including the Jabra Talk 15 (100-92200900-40) unit, inner box, instruction manual, rubber hook caps (right and left), large and small ear hooks, and a charging cable (unused). The outer box is not included. Purchased new in 2020. I have confirmed the operation by connecting it to a smartphone for this listing, but I have experienced some compatibility issues with some PCs (Microsoft Surface) in the past. It's likely a problem with the Surface's BT module, but I couldn't confirm it, so I'm including it as reference information. Also, there is a brown, sticky stain on the mesh part of the speaker. It's not visible when the right ear cap is attached, and I suspect it's caused by the internal adhesive degrading or something similar (I don't think it's dirt from use).
