Used, working condition. This is for the main unit only. Battery replaced with a new one (December 2, 2025). The exterior has some scratches. Please examine the photos carefully before purchasing. I hope that those who understand that this is a used item will purchase it. All music playback operations, charging, initialization, and synchronization are normal. Continuous playback was 13 hours. The volume setting is the initial setting (default value) when synchronized with iTunes. It's a relatively loud volume. Please consider the time as a reference. Please contact me within 2 days for initial defects. I will address issues other than the exterior. Water-damaged items and those with signs of disassembly are not covered. Thank you for your understanding.
