Compatible Head Strap for Quest 3 and 3S

The BoboVR S3 Pro head strap is designed for the Meta Quest 3 and Quest 3S headsets. It integrates an adjustable fan that cools the headset during use. The package includes twin B100 batteries and a BD3 charging dock. This accessory kit is intended for VR users who want longer sessions with active cooling.

10,000 mAh Batteries and Three-Bay Dock

Each B100 battery provides 10,000 mAh capacity for extended play time. The BD3 dock charges up to three B100 batteries simultaneously and shows charge percentages on its display. The new architecture separates the discharge module from the pack, reducing heat and improving discharge efficiency by 6 percent. Low-battery sound alerts and accurate level readings are included.

Upgrade from Older BOBOVR Battery Systems

This kit replaces earlier BOBOVR straps that used the B2 battery system. B2 and B100 batteries are not interchangeable, so owners of the previous generation must adopt the new platform. The jump is worthwhile when you need the improved efficiency, active cooling and the ability to hot-swap multiple batteries via the three-bay dock.
