I urgently purchased these earphones while traveling in South Korea on 2025/9/3 after losing my previous ones. I am selling them because the feel didn't suit me. I have only used them for a short time. The receipt as proof of purchase is attached to the box (I will remove it neatly before shipping if you don't need it).
