M2pro is a battery version head strap specially designed for Quest2. The design team optimized many details on the basis of the original M2, which improved the overall comfort and practicality of the head strap.

The dedicated battery pack weighs only 140g, achieving weight balance before and after. Compared with the traditional power bank, it greatly reduces the burden on the head;
The battery pack adopts a magnetic quick-release design, the battery can be removed and charged without affecting the use of Quest2. Two battery packs Hot swap can achieve unlimited battery life (the second battery needs to be purchased separately);

The battery capacity of a single battery pack is 5200mah. A single battery pack can add about 3 hours of battery life to Quest2, and can provide a maximum of 15 watts of fast charging power; an additional Type-c interface is reserved for powering other accessories.

The redesigned shape of the back of the head brings a larger contact area and improves the overall wrapping and comfort; the stressed parts are replaced by polymer materials to improve toughness and further reduce the risk of fracture.
