Thanks to you, we have exceeded 3,000 total transactions for refurbished SONY products across all sales channels! Thank you very much! ◆◆Product◆◆ SONY WF-C700N Right Earbud Only This is a refurbished product sourced from a manufacturer-certified factory (a product returned for some reason, which has been repaired to remove the problem, and refurbished to a condition comparable to new, including functionality and battery life). It is a very clean product with no noticeable scratches or stains. You can also pair different colors, allowing you to be stylish with asymmetrical colors or make it easier to distinguish between the left and right earbuds. ◆◆Pairing◆◆ Although SONY officially states that you cannot purchase a single earbud separately and pair it, pairing is possible by resetting and initializing the device (refer to the official website for how to reset and initialize). Also, for the WF-C700N, pairing is possible even if the firmware version of the earbuds is different. Please feel free to contact us if you have any questions. ◆◆Ear Tips◆◆ LL size ear tips are included (can be changed to SS or M). ◆◆Shipping◆◆ We will protect the product with a waterproof bag and bubble wrap, and ship it in an envelope. ◆◆Returns◆◆ We thoroughly check the operation, but if there is a problem, please contact us within 7 days of receiving the product, before giving a rating. Please note that we cannot accept returns after you have given a rating. You will be responsible for the return shipping costs. ※We are also selling on other flea market apps, so we may delete the listing without notice.
