Airpods Pro 2 random ''chirm'' sound.

Hello,

I have Mac and I used to have an iphone before I give it to my mom. Now I am an android user. I use my airpods pro 2 with my android device. Nothings wrong except this chirming sound.

When I move it after a long time like 20 30 min it starts chirming. I deleted find my connection from my old iphone and currently my mom uses it and there is no connection in find my app and also no connection in bluetooth section. What is my airpods problem? It is really annoying, it always chirming when it shouldn't be.
