Ming-Chi Kuo says it will weigh less than 150 grams

A weight of 150 grams would make Apple’s headset lighter than the Oculus Quest 2 (503 grams), Microsoft’s HoloLens 2 (645 grams), and the Valve Index (809 grams). It would be lighter than Google’s Daydream View, a fabric VR headset designed to hold your phone, which weighed 220 grams. The headset could even be lighter than your iPhone, given that the standard iPhone 12 weighs 164 grams.

The headset, codenamed “N301,” may also have 8K displays, eye-tracking technology, and more than a dozen cameras to both track your hand movements and capture footage that can be displayed inside the headsetapp
