A:AnswerThere's no current details regarding what specific USB version it uses (USB-C describes the connector, not how fast the port goes), however that shouldn't really matter as you're not transferring data across that port like you would on an iPhone 15 (which has a USB-C port at USB 2 speeds due to a lack of a USB 3 support on the A16 Bionic since it was last years iPhone 14 Pro SOC which used lightning) and on an iPhone 15 Pro (which has USB-C at USB 3.2 Gen 2 speeds since the A17 Pro was designed with that capability in mind).
If you're speaking about charging speeds, I highly doubt (but it's not confirmed) that it's going to go faster than the current 5W limit since the battery isn't that large.
A:AnswerYes, Apple AirPods can work with Android devices as Bluetooth headsets, but some features won't be available.
Some features that won't work with non-Apple devices include: Siri, Ear detection, Double-tap function, and Music pausing when AirPods are removed from ears.
A:AnswerBest earbuds I have used in the gym. Workout 6 days a week and these have outlasted any part I have had over the years. I have to sometimes adjust when spinning but that is usually bc the room is so hot and massively sweating. Didn’t have the same issue when jogging. Would totally recommend for the gym.
