Headphones Whether your friend lost them or broke them people are always in need of a new pair of headphones. When buying someone headphones it is important to make sure that they are compatible with the friends device. Iphones 7 and higher require headphones that can connect through the charger, while Iphones 6S+ and lower have the standard 3.5 mm audio jack. Samsung Galaxies all still use the 3.5 mm audio jack as well.
