I love these so much! The case itself has 4 lights that indicate that it is fully charged. I thought that meant the earbuds, but actually they have red and blue light to indicate they are charged. The case itself has light because it holds charge too! It holds a long time, I've charged the buds twice and left the case for four days now, and only one light is gone of the four. They fit super snug, are easy to snap in to charge because they are magnetic, and have the BEST sound. I LOVE LOVE LOVE these!
