Sony wireless earbuds, black, with ear tip set. - Brand: Sony - Model: Wireless Earbuds - Accessories: Ear tip set - Color: Black - Model Number: SBH82D Thank you for viewing. I stored these after purchasing them and rarely used them. Therefore, I am unsure about the battery life. (I was able to connect them to an iPhone, and sound played.) ★Items other than those shown in the images are not included. (Outer box, cable, instruction manual, etc.)
