This is an AI-diagnosed item, so there may be errors. Please make your own judgment based on the photos. Returns are not accepted to prevent replacement. Functionality has been confirmed. This is a new, unused item, so please make your own judgment based on the photos, as they represent everything included. Returns are not accepted to prevent replacement. Other features: Wired/Wireless compatible. There may be odors, stains, damage, and wrinkles due to storage. Please make your judgment based on the photos. Please read the profile before bidding. For long-term stored items, or items that have been stored, I will check the sound before shipping, but I cannot check the battery, etc., as it would make the cord and battery itself used. Therefore, returns are only possible for initial defects. I will cover the shipping costs, and the price is lower than new items accordingly.
