This is a wearable neck speaker that rests on your neck and shoulders. ◯ I purchased it several years ago, but I haven't used it much. It has been sitting on a shelf at home for several years, so there are a few minor scratches and dust that are not very noticeable. ◯ This is a used item, so please purchase only if you understand this. ◯ I have lost the USB charging cable, so I will include a non-genuine cable. I will ship the main unit and the cable only.
