※Please understand that this item is a junk item before purchasing. Returns are not accepted to prevent product substitution. Disinfected with alcohol wipes. The case and the left earbud function normally, but the right earbud is sometimes not recognized by the case and does not charge.

Also, regarding the right earbud, after using it for several tens of minutes, a warning sound indicating low battery will play, even though the earbud has sufficient charge. You can still use it for a longer period of time despite the warning. The left earbud does not have such a warning sound. USB-C cable and outer box are not included. The items included are the earbuds themselves, the charging case, ear tips in 3 sizes (one used set will not be included for hygiene reasons), wing tips in 2 types, and the quick start guide.
