Sony WI-1000X wireless, neckband-style earphones in good used condition. Only thing is that the earpiece's wires got a bit stretched out over the years but no contact issues, and the power button is bit worn/bulging. But everything fully works.No charger, but it only requires a simple micro-usb cable to do so.It can be also used in wired mode, which requires a micro-usb to 3.5mm jack adapter.
