I have a pair of air f10 wireless earbuds with charging case for sale. The right earbud appears to die very fast basically right after it is turned on. The other earbuds appears to hold a charge and the charging case appears to work and hold a charge. I am not sure if there is anything else wrong with these so I am selling them as is no returns. The default item description may be wrong so what you see in the pictures is what you will get.
