BOBOVR Battery Relief Strap S3 PRO for Meta Quest 3 — Adjustable Comfort Fit Headstrap

BOBOVR S3 PRO Battery Relief Strap for Meta Quest 3 is an adjustable comfort-fit headstrap designed to redistribute headset weight, accommodate an external battery and extend headset runtime for Meta Quest 3 users. The strap integrates a Honeycomb Pad for improved fit, a rear battery mount compatible with the B100 system and a built-in ventilation module to maintain comfortable temperature during extended VR sessions.

Advantages

The BOBOVR S3 PRO reduces facial pressure and improves balance by shifting weight to the rear, while the Honeycomb Pad conforms to the head for extended comfort. The detachable B100 battery delivers 10,000 mAh usable capacity with improved discharge efficiency and reduced overheating, and supports 20 W fast charging. An aircraft-turbine‑inspired ventilation system with 100 levels of adjustment cools the headset quietly. The strap also features one‑hand, quick battery replacement, an easy-to-read charge indicator and adjustable/removable support for personalized fit.
