While Apple might focus on MacBooks during Monday's "Unleashed" event, the third-generation AirPods might appear at the October 18th event. Weibo leaker @PandaIsBald claims the redesigned AirPods will appear alongside the new "M1X" Macs. If accurate, it'll be the first significant redesign for the AirPods line since the AirPods Pro in 2019.
If you're waiting for the MacBooks more than the AirPods, those are expected to be 14-inch and 16-inch MacBookPro models with improved performance, a new design, and a mini LED display with ProMotion (allowing for a 120Hz refresh rate). We might also hear about the public release of macOS Monterey.
