AirPods 4 labeled as headphones on iPhone

Today i bought the airpods the normal ones. When i opened them and paired them with my phone i noticed that the pop up that normaly shows how much battery didnt show. Then i checked my settings and the airpods where labeled as headphones that means that my phone cant show me how much battery has the airpods and the case . I tried every possible way and still cant fix it.Also i cant get them to lower or make my noise higher.
