Incoming call ringing tone

Hi when I get a call with my earbuds on I can hear the call in my ears. I also notice the phone also makes the ringing tone.

does that make sense ? Or should I only be able to hear the ringing tone in my ear buds.

Thanks in advance

StevenKessel Also das ist einfach so man kann es nicht ausmachen ja es macht nicht so viel Sinn aber kann man nichts machen
