Apple announced AirPods Pro on October 28, 2019, and released them two days later on October 30, 2019. They include features of standard AirPods, such as a microphone that filters out background noise, accelerometers and optical sensors that can detect presses on the stem and in-ear placement, and automatic pausing when they are taken out of the ears. Control by tapping is replaced by pressing a force sensor on the stems. They are rated IPX4 for water resistance.
