When the Apple Watch Series 8 and the second-generation Apple Watch SE were unveiled, Apple’s website showed that both models could only support Bluetooth 5.0 protocol, but Apple now says they actually support the newer Bluetooth 5.3 standard.
Apple has officially confirmed that both models support Bluetooth 5.3, at least in the United States. That means other markets may only support up to Bluetooth 5.0.
According to Apple, all iPhone 14 series models, the second generation AirPods Pro and Apple Watch Ultra support Bluetooth 5.3.
Bluetooth 5.3 is described as having “a number of enhancements that improve the reliability, range and user experience of many Bluetooth products,” such as the LE Audio audio specification, but there is no evidence that Apple supports LE Audio audio in its latest products.
