BOBOVR S3 Pro Head Strap with B100 battery and fan | for Meta Quest 3 / 3S

The factory strap on the Meta Quest 3 and 3S quickly makes itself felt: it digs into your face, slips, and after a longer session it simply hurts. The BOBOVR S3 Pro Super Strap (also known as the S3 Pro Head Strap) settles the matter for good, giving you three things in one: a sturdy battery strap frame, a 10,000 mAh B100 battery and a cooling fan.

The weight of the goggles lands where it should on the back of your head, not on your cheeks and nose. That means long gaming and VR workouts no longer wear you down, even after hours. Swap the B100 battery in seconds and dive straight back in, with no mid-session charging.

The built-in fan draws heat away from your forehead and keeps lens fogging in check, which you'll feel most in movement games and VR fitness. The rear dial cinches the strap to any head in a heartbeat.

Manufacturer's storage and use tips

To ensure long battery life and avoid operating errors, the manufacturer recommends:

• ✅ Charge the B100 battery and the Meta Quest 3 / 3S goggles separately, not at the same time.
• ✅ Use a good-quality USB-C charger and cable.
• ✅ For longer storage, keep the battery charged to 60-80%.
• ✅ Don't leave the battery on the docking station or connected to the head strap for long periods.

Following these rules significantly reduces the risk of errors and extends the battery's lifespan.
