This is a used, defective item. Purchased in 2024, I originally bought the blue color, but then lost one earbud, so I bought the black color. The box is the blue one. The original price was 39,600 yen including tax. →So, the earbuds themselves are black, and the case is blue! I was using them until a month ago, so the earbuds themselves were working, but I recently had the opportunity to buy new ones, so I'm putting these up for sale! No claims and no returns, to prevent swapping.
