[All] AirPod Pro makes a squeaking soundㅠㅠ

I bought it from the Apple website in February, but I keep hearing a buzzing sound from my right AirPod.

If I bring this Antz, will you exchange it for me?

I remember taking my AirPods to a store before because I thought there was something wrong with them, but they said there was nothing wrong with them...ㅜㅠㅠ and I ended up wasting my timeㅠㅠ
