Operation confirmed. Power, various functions, and remote control operation are all good. After a full charge, music was played at a medium volume for over 8 hours and it continued to play. The inline remote has peeling (see image 5), but there are no issues with operability. There is a crack on the top of the neck rest (see images 6 and 7). The charging port cover is missing. To keep the listing price down, it will be carefully packaged with waterproof protection and bubble wrap, placed in a dedicated box, and shipped via Yu-Packet Post. The item has been disinfected with alcohol. It has been cleaned as thoroughly as possible. Please use with confidence. If there are any defects within the scope of the photos and description, we will accept returns and refunds, so please purchase with confidence.
