We have tested all functions before listing. The item has been cleaned with alcohol and initialized. Upon close inspection, there is a small scratch on part of the right earphone, but it is not very noticeable. Battery life is also not an issue. Please check the photos for detailed condition. The items included are only the earphones themselves. Please prepare your own earpieces. Although it is a beautiful item, please understand that it is a used item and there may be wear and tear (such as battery degradation). Please refrain from purchasing if you are sensitive to such details. No price reduction will be offered.
