Used only once for an indoor event 2-3 years ago. I believe everything that came with it at the time of purchase, including the manual, parts, and other items, is complete. It seems that it is often sold for over ¥10,000 on other sites, so I think it's a good deal. I think it's in beautiful condition. #event #speaker #loudspeaker #sound #wireless #microphone #twoMicrophones #portable #compact #convenient #expand #USB #instructionManual #manual #easy
