Adjustable dial fit

The K4 QS02 head strap is designed for Meta Quest 3 and 3S headsets. A rotary dial at the rear lets users tighten or loosen the fit in seconds. Memory foam and soft PU leather cushion the forehead and rear cradle. The strap weighs 233 grams and adds minimal bulk to the headset.

Who benefits and who does not

Casual players and families sharing one headset will appreciate the quick 52-degree hinge adjustment that suits adults and children. Buyers who want an integrated battery for longer sessions cannot use this model because it has no power pack. Users who prefer a flat-back design for lying down should consider a different strap.

Weight and balance

The strap weighs 0.5 pounds and uses an enlarged rear headrest to shift mass away from the face. This balance reduces facial pressure during active movement. The 233-gram figure is the single specification that decides whether the trade-off between light weight and battery-free operation matches your needs.

Questions about this item

How do I verify the K4 head strap is balanced correctly after fitting it to my Quest 3?

The 233 g strap uses an enlarged rear headrest to shift weight off the face; when the dial is tightened so the headset sits level without pressing on your cheeks, the balance is set.

What comes in the box with the K4 QS02 and what must I purchase separately?

The package includes the K4 head strap with integrated dial and hinge; the P5000 5000 mAh power bank and any charging cable are sold separately.

Which K4 variant should I choose between the standard QS02 and the Flex version?

Choose the QS02 for a lighter 0.5 lb design with a 52-degree hinge for quick on-off, or the Flex if you need a flat-back strap for lying-down use and foldable portability.
