The new AirPods offer a wireless charging case, as we expected. You can buy it with the new AirPods themselves ($199, £199, AU$319), or if you'd rather add wireless charging to your first-gen AirPods, you can buy the case separately for $79.

The new AirPods are also available with a standard charging case for $159 (£159, AU$249).
