Thank you for viewing. The items are a Yamaha UE500 and a power adapter. I have checked the operation thoroughly and found no particular problems. I also confirmed synchronization with a PC (photo 8). However, as this is an item from a previous era, there is a possibility of malfunction after the product arrives. Please refrain from purchasing if you are overly concerned about the condition. It is from a non-smoking environment and there are no pets. Please judge the condition of the product from the photos.
