I'm selling these because they don't seem to fit my ears. These are refurbished (purchased 2023/10/11) with a new genuine battery (Zenipower z52h) installed. I used them for about a week without any problems, and the battery life is close to new. Please refrain from purchasing if you are sensitive to used items. *Please check the photos for the detailed condition.
