Good day

After checking the manufacturer's website, here is the information:
"The TCL NXTWEAR S is an evolution of the TCL NXTWAR Air, offering a range of features that free users from fixed screens. The smart wearable glasses offer a wide viewing environment equivalent to a 140-inch screen four metres away, with two 1080p Micro OLED displays that provide a private, high-quality viewing space. TCL NXTWEAR S transforms everyday tasks while enhancing the leisure activities of gamers and streamers - anywhere, anytime."
