Purchased new from Amazon in 2024 (Japanese authorized dealer product with serial number). I personally like this Fiio series very much, and immediately after purchasing this item, I bought the K9 Pro ESS and used it as my main device. This item was used as a sub-device, so the usage time is very short. Although it's a layman's inspection, I believe it's in very good condition with no scratches or stains. Operation confirmed. All accessories are included. In my personal opinion, the sound quality seems almost the same as the Pro ESS. If you have any questions or would like to see photos of specific areas, please feel free to comment. I will take measures against rain and impact and carefully pack and ship the item. Thank you very much.
