Strain Relief Strap BOBOVR E3 for Meta Quest 3 — Adjustable Comfort Fit

BOBOVR E3 Strain Relieving Strap for Meta Quest 3 and 3S is an adjustable head strap that reduces front-face pressure and improves headset stability for extended VR sessions. The strap fits head circumferences from 470 mm to 610 mm and uses a modular counterweight system (2 × 35 g, total 70 g) to distribute headset weight toward the rear. Constructed from ABS and PC with reinforced polycarbonate joints and a soft foam rear cushion, the strap is designed for durability and comfort while standing, sitting or lying down. A magnetic power input and USB-C output allow the strap’s integrated battery pack to power the Meta Quest 3/3S during use.

Advantages

The modular counterweight system balances the headset to reduce facial pressure and fatigue. High-quality ABS and PC materials with reinforced joints increase durability during intensive use. The soft occipital cushion improves fit and stability across different positions. Manual multi-point adjustment provides precise sizing for a personalized fit. Built-in magnetic power input and USB-C output offer pass-through charging with two output modes (5V=3A and 9V=2.5A) for uninterrupted VR sessions.

How to use

Put the strap on and adjust the top and rear adjustment points to center the Meta Quest headset on your face. Add or remove the modular 35 g weights to achieve the desired balance and reduce front-face pressure. Connect the included B100 battery pack to the magnetic input when you need to power the headset, and use the supplied USB-C cable for charging. Tighten manual adjustment points until the headset feels stable but not over-constricted.

Recommendations

For optimal comfort, start with one 35 g weight and add the second if additional rear balance is needed. Charge the battery pack before long sessions and check that manual adjustments are secure before movement-intensive experiences.
