  • Compatible with Meta Quest 3:Reduce facial pressure: It adopts a suspended design and supports multi-point adjustment, which evenly transfers the original facial pressure of the host to the head. If you want, you can even remove the facial interface to fully enjoy the transparency of MR mode. 
  • Power supply is more convenient: The battery pack adopts a magnetic quick-release design, and the battery can be detached and charged, which does not affect the use of VR host. Two battery packs are hot-swappable for unlimited battery life (the second battery pack needs to be purchased separately).
  • Reducing the weight of the head battery: We designed a dedicated battery pack B2 for the VR host, which weighs only 140g, which can balance the front and rear weights. Compared with the traditional power bank, the burden on the head is significantly reduced.
  • Double the battery life: The battery capacity of a single battery pack is 5200mah, adding about 1.5 hours (APP depends) of VR time.
  • Hassle-free Warranty: For any pre-sale or after-sales issues, an 18-month hassle-free warranty is guaranteed to feel free to contact us.

FAQ

Which headsets is the M3 Pro for?

Meta Quest 3 and Meta Quest 3S.

What battery does it use, and does it work with the BM60 or B100?

It uses the B2 battery. The B2 is not compatible with the BM60 or B100 — each battery has its own strap and dock, and they are not interchangeable.

How much extra playtime does the B2 add?

The B2 delivers roughly 70–80% of a full Quest 3 charge — about 1.5 to 2 hours, depending on the app. Add a second B2 for longer sessions.

Does the M3 Pro help with face pressure?

Yes — the suspended design with multi-point adjustment transfers the headset's weight off your face onto your head.

Does it work with the official Meta Quest 3 charging dock?

You can dock the Quest 3 with the strap cable still connected, and the headset charges normally. The B2 will not charge through the dock, so charge the B2 separately.

Why does my Quest stop charging at about 80% while playing?

For safety the Quest limits on-head charging to about 80%. If it starts below 80% it charges to 80%, then the B2 takes over; off the head it charges to 100%.

Can I use MR / passthrough?

Yes — the facial interface can be removed to use MR mode.

The B2 makes a faint hiss — is something wrong?

No — a slight hiss at the output is normal for the battery and does not affect use.
