The SONY NW-WS625 is a waterproof and dustproof wireless earphone. I used it for jogging, but I'm now using a wired Walkman from the same manufacturer, so I'm selling it. It has been initialized, its operation has been confirmed, the color is black, and it has 16 gigabytes of storage. Returns are not accepted to prevent swapping. Please understand that this is a used item, inspected and stored by an amateur. The current price on Amazon is 24,800 yen, and the used item price on the Sony Store was 21,000 yen. --------------------------- 【Additional Note 1】 There are areas where the black paint on the button surface has peeled off. I checked it by pressing it several times, but it's just the paint peeling, so it shouldn't affect the operation. Please be sure to refer to image 9. 【Additional Note 2】 The remote control battery may be dead, so I will include a new battery. See images 1 and 10. -------------------------- I may change the shipping method between Yu-Yu Mercari Bin and Raku-Raku Mercari Bin. Thank you for your understanding. 【Official Page Explanation】 Connect it to your smartphone, or use it on its own.
