These are wireless BOSE Sport Earbuds. I purchased them as a sub-earphone and only used them when I forgot my main ones. The battery condition is about 25% consumption after 1 hour of use at medium to high volume. Please check the images and purchase with your understanding. If you don't need the box, I will ship only the contents.
