BOBOVR M3 Pro Head Strap with Battery Pack for Meta Quest 3 and Meta Quest 3S, White

The BOBOVR M3 Pro Battery Pack Head Strap for Meta Quest 3 and Quest 3S is a halo-style replacement strap paired with a detachable magnetic battery pack, designed for Meta Quest 3 and Meta Quest 3S headsets. It works as both a weight-distribution accessory and a power extension, using a suspended multi-point adjustment design that shifts the headset's load across the top and back of the head rather than pressing it against the face. The included BOBOVR B2 battery has a capacity of 5,200 mAh and connects to the strap magnetically, adding roughly 1.5 to 2 hours of runtime. A quick-release mechanism allows the battery to be detached or swapped without removing the headset, and spare B2 units can extend sessions further. Power passes to the headset through a USB-C connection, and the strap is fully adjustable.

Weighing 430 g in a white housing, the strap adds moderate weight while reducing reliance on the stock facial interface for support. Two silicone honeycomb comfort pads are included and attach to the contact points for improved cushioning during extended virtual reality or mixed-reality use. The USB-C cable provided handles power delivery between the battery and the headset, but no AC adapter is included, so charging the battery pack requires a separate USB-C charger. The wearing style is head-mounted, and the single USB-C port serves as the only wired interface on the device. Construction is plastic throughout the halo frame and adjustment arms, in line with the category's typical material choices.
