Apple iPhone 16, Apple Watch Series 10 and AirPods 4 debut around the world

Apple on Friday greeted customers at its stores around the world for the debuts of the iPhone 16, Apple Watch Series 10 and AirPods 4.

The new products were announced at an event earlier this month and have been available for pre-order since Sept. 13. The company lit up the glass cube at its Fifth Avenue Apple Store in New York City, in a nod to the enhanced Siri, which will light up the borders of the new iPhone’s screen when that feature rolls out next month.

Apple’s latest iPhones mark the company’s latest move into artificial intelligence, with new Apple Intelligence features that will begin to launch in October. The new features will allow customers to rewrite text, remove objects from photos and speak with an improved Siri. The software advancements will only be available on iPhone 16 and last year’s iPhone 15 Pro devices.

But Apple shares slid on Monday after analyst reports suggested that demand for the latest iPhones was lower than expected. TF Securities Analyst Ming-Chi Kuo said in a note on Monday that first-weekend sales were down about 12% year-over-year from the iPhone 15 last year. Barclays, JPMorgan and Bank of America also noted shipping times could translate to lighter demand for the more expensive iPhone Pro models compared to last year.

The Apple Watch Series 10 offers a larger screen than that of earlier models. It will support, along with the earlier Series 9, new Sleep Apnea detection, as well as other new features. The AirPods 4 offer a refresh with a smaller charging case and an option with noise cancellation.

CNBC reviewed the new iPhone 16 Pro Max and the Apple Watch Series 10 earlier in the week.
