If you bought a brand new pair of AirPods Pro, you’ll receive the new charging case with MagSafe magnets for alignment.

The case is essentially the same as the previous one but now has built-in magnets for aligning perfectly with the MagSafe charger Apple sells. The case remains compatible with any Qi charger but thanks to the addition of magnets, the MagSafe puck will now snap into place for the perfect wireless charging experience.
