Purchased in 2021. I bought a replacement because I thought I had lost the original, so this item has been stored unused. A popular model from the Swedish brand "Sudio." These Bluetooth earphones feature a powerful 10.2mm dynamic driver housed in aluminum. They are lightweight and stylish, making them ideal for commuting to work or school. 【Important Notes】 ・This is a new, unopened item, so the operation has not been confirmed. ・It has been stored in the same condition as when purchased. ・A certain period of time has passed since the purchase, so the manufacturer's warranty has expired. ・In the unlikely event of an initial defect, please contact us within 5 days of receiving the product, before leaving a review.
