Thanks to you, we've surpassed 3,000 total transactions for refurbished SONY products across all sales channels! Thank you very much! ◆◆Product◆◆ SONY WF-C700N Left Earbud Only This is a refurbished product sourced from a manufacturer-certified factory (it has been returned for some reason, the issues have been resolved, and it has been reconditioned to a condition similar to new, including functionality and battery life). There is one minor scratch visible in the photos, but the rest of the item is in very good condition. You can pair it with a different color earbud, allowing you to create a stylish asymmetrical look or easily distinguish between the left and right earbuds. ◆◆Pairing◆◆ While SONY officially states that you cannot purchase a single replacement earbud and pair it, pairing is possible by resetting and initializing the device (refer to the official website for reset and initialization instructions). Furthermore, pairing is possible even if the firmware versions of the WF-C700N earbuds are 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◆◆ The item will be protected with a waterproof bag and bubble wrap, and then shipped in an envelope. ◆◆Returns◆◆ We thoroughly check the product's functionality, but if there is a problem, please contact us within 7 days of receiving the item, before leaving a review.
