This is a used item with some issues. Purchased in 2024, I initially bought the blue version. Later, I lost one earbud and bought the black version. The box is the blue one. The original retail price was 39,600 yen (tax included). → 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 fine, 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 any swapping.
