The battery is swollen, and the back cover won't close. When connected to the included earphones in the photo, no sound comes from the left earphone. The right earphone does produce a small sound. Therefore, I am selling this as a junk item, with no guarantee of functionality. Each operation was possible. (Hold function is a bit difficult to use because the back cover won't close.) #YupakuWalkman ↑ I also have other audio-related items for sale, so please take a look if you'd like!
