I am selling these earphones because I bought a new pair. There are no operational issues. Also, I haven't used them much, so I don't feel like the battery has depleted much. Since they have been used to some extent, there are some scratches and dirt, so please refrain from purchasing if you are sensitive to such things! I will include a silicone case (see photo 8). There are slight marks on the lid of the case where the silicone case was attached. Wireless earphones with high sound quality and long battery life. - Brand: soundcore - Model Name: Liberty 4 - Color: Black - Included Accessories: Ear tips (S, L sizes) - Waterproof Standard: IPX4 - Battery Life: Up to 28 hours Thank you for looking.
