BOBOVR M3S PRO White Meta VR Head Strap sku-5571559943

BOBOVR M3S PRO, sku-5571559943, is a White Meta VR head strap sized for 18.5-24.8inch head circumference. The source also calls the strap S3 Pro. It works with Meta Quest 3 and Quest 3s only. Its swappable B100 battery system separates the discharge module from the pack to reduce battery heat, improves discharge efficiency by 6% over the previous model, and adds low-battery sound reminders and a battery-level display.

Compared with B2, the B100 keeps the same volume while increasing capacity from 5200mah to 10000mah, a 92% increase, with a 28% weight increase. The stated usable capacity is 2 times that of B2. A built-in head air-cooling system offers 100 levels of fan-speed adjustment; press the roller to turn it on.

The flattened rear structure has adjustable height and removable overhead support for seated or reclined use. Cooling requires B100 and does not work with a B2 battery pack. The battery uses two 5000mAh lithium cells in series for 7.3V total, equivalent to a single 10000mAh/3.65V pack.

The box contains a head strap, B100 battery pack, honeycomb pad, USB-C cable and instructions; the VR headset and controllers are not included.
