If you have second-generation AirPods or later, this also includes AirPod Pros, and you've set up the "Hey Siri" function on your iPhone, you can simply say "Hey, Siri," and then ask Siri to adjust the volume.
如果你有第二代 AirPods 或更之後的版本(包括 AirPod Pros),且你已經在 iPhone 上設置了「嘿 Siri」功能,那你指需要說「嘿,Siri」,然後要求 Siri 調整音量。
