Earfun Air Pro 3 Black, charging case only, brand new, unused. I can also include a charging cable if you'd like. I've checked to see if it charges, but if it's defective, I'll accept returns. To prevent swapping, please check if it charges before removing the seal indicating it's new. Why not choose new over used, where you don't know how the battery has been used? This isn't a guarantee that it's a new, opened item, but I'm likely the only one selling a new, opened item below the retail price.
