KIWI Design K4 Boost<\/p>\n

A head strap that powers your headset<\/h2>\n

KIWI Design K4 Boost is a head strap for Meta Quest 3 and Quest 3S that helps balance the weight and powers your headset during VR sessions. Its battery extends playtime, while the damped hinge makes the headset easier to put on and take off. It is designed for longer sessions with fewer charging breaks.<\/p>\n

Extra power for longer sessions<\/h3>\n

Comfortable fit for hours<\/h3>\n

Reinforced, thicker back support of the head together with an optimised counterweight<\/strong> distributes the headset's weight evenly, relieving pressure on the face and neck during longer sessions. The strap circumference can be adjusted in seconds using quick adjustment knob<\/strong>, so you will find the perfect setting also when the set borrows someone else at home or in class.<\/p>\n<\/div>\n
