If you’re considering the gen2 AirPods, watch the video embedded below.
One point Rene highlights is that the new AirPods, courtesy of the H1 chip, are Bluetooth 5.0 compatible. Bluetooth 5.0 is about twice the speed of its predecessor (about 48MBps) and capable of longer distances between devices. Obviously, to gain these benefits, the devices on each end need to support Bluetooth 5.0.
Fortunately, all modern iPhones support Bluetooth 5.0 (the iPhone 8 does, the iPhone 7 is at Bluetooth 4.2). And Bluetooth 5.0 is backward compatible.
