【Product Condition】 ・Purchased new and used at home for about 2 years as a sleep-with-headphones device. ・Never used outdoors, and since a silicone cover was attached, there are no noticeable scratches or stains. ・There is some minor wear and tear from use (especially from opening and closing the lid), but there is no significant damage. 【About the Battery】 ・Since it has been used for 2 years, the battery life is considerably reduced compared to when it was new. I tested it with a full charge once, and the right earbud's battery drains faster, while the left earbud performs well and lasts longer. Please consider this beforehand.
