Panasonic Wireless Earphones RZ-S520W (Black) Purchased 7 years ago. Selling because I bought new earphones. Used frequently, so there are scratches and signs of wear overall. Also, the contact between the earphones and the case is sometimes poor, but they can be charged and used without problems if you put them back in. Operation has been confirmed. Recommended for running or as a secondary device. • Brand: Panasonic • Model: RZ-S520W • Type: Wireless Earphones • Color: Black • Accessories: Charging case (can be opened and closed) Please note that this is a used item, so no claims or returns are accepted. We look forward to your purchase if you understand this.
