Thank you for viewing. FiiO FIO-FW5-B (C) Purchased new and used indoors for about a month. There may be damage to the box, in which case there are photos. Please check them. Both the outside and inside of the case are clean, but there is a slight feeling of use. Also, there is a thin, hairline crack near the USB charging port on the back of the case. Please check the photos. The firmware is currently updated to the latest version, 1.6. All settings have also been reset. The ear tips that were initially attached are unused, and the earphones and case have been disinfected. *When you receive the item, the earphones and case may be out of charge. If the case indicator or the earphones do not light up when you open the case, please charge them fully before use.
