Siri speaking louder in my AirPods

Hi,
I’m using iOS 26.4 on an iPhone 16 Pro. I am also using the AirPods Pro 3, and I’m having a strange problem. I have adjusted Siri so that it speaks at an acceptable volume on my phone. When I plug in AirPods, though, the volume usually is very loud. I can tell it to turn down, and it might remember for a while, but it usually turns up again if I adjust the volume on the phone at all. I hope this is making sense. If I turn off all announcednotifications, Siri will remain at a set volume. Otherwise, the volume issue persists. Has anyone else had this issue?
