This is a used item. Everything in the photos is included. Contents: Main unit 3 USB cables Band Neck strap The USB cables are Type A, Type mini-B, and Type C. The main unit can be powered via USB or with 4 AA batteries. It seems that the AA batteries are only for nickel-metal hydride batteries. I haven't used the included band, but it shows signs of aging. I think a commercially available wristband can be used as a substitute. The neck strap's authenticity is unknown. A commercially available saxophone strap with a small hook can probably be used as well. Basic playing is not a problem, but I haven't confirmed all the functions. If there are any specific functions you want to check, I will test them. Please feel free to ask any questions.
