(Can be charged with a standard microUSB cable) *The outer box has some scratches and stains. ⚠ Microphone function has not been tested. ⚠ Please understand that there is a possibility of battery degradation due to long-term storage. Overall, the condition is clean, but please refrain from purchasing if you are sensitive to minor imperfections, as this item has been stored at home. I will ship with care. Thank you.
