Mark Gurman, writing for Bloomberg:
The model coming as early as this year will let people summon Apple’s Siri digital assistant without physically tapping the headphones by saying “Hey Siri.” The function will work similarly to how a user activates Siri on an iPhone or a HomePod speaker hands-free. The headphones, internally known as B288, will include an upgraded Apple-designed wireless chip for managing Bluetooth connections. The first AirPods include a chip known as the W1, and Apple released the W2 with the Apple Watch last year.
The idea for the water-resistant model is for the headphones to survive splashes of water and rain, the people said. They likely won’t be designed to be submerged in water. The latest iPhones can survive splashes, while the Apple Watch is considered “swim-proof.” Apple’s plans could change or be delayed, the people said. An Apple spokeswoman declined to comment.
