Plenty of phones charge over USB-C and move files through the same port, yet never send a picture out of it. The shape of the port does not reveal whether video can travel through it.
Changing where the picture comes from solves it. RayNeo GT and RayNeo GT Max pair with RayNeo Pocket TV Pro, a pocket Google TV player that takes over the job of video source. Lightning iPhones have their own adapter route, and RayNeo Air 4 Pro comes in an official bundle with the Pocket TV Streaming Box. For Dolby Vision without a phone, GT or GT Max with Pocket TV Pro is the pairing; for one box that covers glasses and player together, the Air 4 Pro bundle is the simpler buy. The phone stays in a pocket for messages and calls.
Phones that charge over USB-C but keep the picture inside
A USB-C connector is only the shape of the plug. Whether video travels through it depends on how the phone maker wired the port, and many phones wire it for power and data alone. RayNeo GT, GT Max and Air 4 Pro connect directly to phones whose USB-C port carries a DisplayPort signal.
Two groups of phones take another route:
- Android phones whose USB-C port carries charging and file transfer only.
- iPhones with a Lightning port, up to iPhone 14, which send video through Apple's own connector.
The first group is best served by a separate player that brings its own picture: Pocket TV Pro for GT and GT Max, or the Pocket TV Streaming Box in the Air 4 Pro bundle. The second group has a cable route through Apple's adapter as well as the player route. The full background on DisplayPort over USB-C, and every alternative path, is in the guide to using AR glasses without USB-C DP Alt Mode.
Pocket TV Pro as the source instead of the phone
Pocket TV Pro runs Google TV on its own and connects to GT or GT Max with a USB-C cable. It is built as a portable, all-in-one streaming setup that does not rely on a compatible smartphone, so the phone's port stops mattering. The player brings the apps, the storage and the voice search that a phone would otherwise provide.
With Pocket TV Pro, GT or GT Max forms a Dolby Vision AR glasses system, so the phone-free route is also the route to Dolby Vision playback on the GT series.
Pocket TV Pro is an optional companion rather than a requirement. Anyone who later moves to a phone with DisplayPort video over USB-C can plug GT or GT Max straight into it and keep the player for travel days. The spec-by-spec breakdown lives in the Pocket TV Pro specs guide.
Preparing Pocket TV Pro for a phone-free setup
Some preparation at home turns Pocket TV Pro into a complete source of its own.
- Sign in to the streaming apps on Google TV with the accounts already in use on a television or a phone.
- Copy video files, such as recorded talks or family videos, onto a microSD card and insert it. The player takes cards up to 2TB on top of its 64GB of built-in storage.
- Connect the glasses to one USB-C port on the player with the cable from the glasses box, and a USB-C charger to the other port when a long session is planned.
- Use Google Assistant for search and playback, so a title can be found and paused by voice instead of scrolling through menus.
Lightning iPhones through Apple's AV adapter
A Lightning iPhone does send video, just not over USB-C. GT and GT Max accept it through a short chain: the iPhone goes into Apple's Lightning Digital AV Adapter, its HDMI output goes into the RayNeo HDMI Adapter, and the USB-C cable from the glasses box finishes the run. Apple's adapter is sold by Apple, separately from the glasses.
This route mirrors the iPhone itself, so the phone's own screen, including its photos and apps that support an external display, appears on the virtual screen. Pocket TV Pro takes a different route and replaces the phone as the source. Owners of a Lightning iPhone can choose by what they want to watch: their phone's own library through the adapters, or streaming and microSD films through the player. Each piece of the cable chain is covered in the guide to connecting a Lightning iPhone or older iPad.

GT and GT Max take either route through the same USB-C cable, one source at a time.
Air 4 Pro with the Pocket TV Streaming Box bundle
Air 4 Pro has its own matched player: the Pocket TV Streaming Box, which ships with the glasses in the official Air 4 Pro + Pocket TV bundle. The same box is sold on its own as RayNeo Pocket TV: Google TV in a portable case, with a library of 400,000+ movies and episodes spread over 10,000+ apps, its own built-in storage, and a slot that takes microSD (TF) cards up to 2TB.
Air 4 Pro turns that player into a 201-inch private screen, with a Full HD Micro-OLED display that refreshes at up to 120Hz. Bang & Olufsen tuned speakers sit in the temples, so a film from the player plays through the glasses themselves, in a 76g frame. Glasses and player arrive together, ready to play without a phone.
Screen size and fit across GT Max, GT and Air 4 Pro
With the source settled, two questions separate the glasses.
How big should the screen feel? GT Max is the widest of the three, with a 59° field of view and three virtual screen sizes of 227, 267 and 307 inches. GT sits at 46° with 136, 201 and 231 inches, and Air 4 Pro offers 201 inches across 46°. GT and GT Max also add native 3DoF tracking, and their Pinned mode holds the screen in one place instead of moving it with every turn of the head.
How should it fit? GT Max comes in S, M and L optical sizes chosen at checkout to match the wearer's interpupillary distance, at 78g. GT uses a fixed 64mm optical design at 68g, with its nose pads and wearing position used to center the picture, and it is the lighter choice for long viewing. Air 4 Pro weighs 76g, with adjustable nose pads and flexible temples.
All three carry Bang & Olufsen tuned speakers, so sound comes with the picture on every model. For the largest, most cinema-like screen and a fit matched to the eyes, GT Max leads; on long trips where every gram counts, GT is the lighter frame. Air 4 Pro fits a viewer who wants films from one matched kit, with a display that refreshes at up to 120Hz.
Source-device FAQ
Can a tablet stand in for the phone?
An iPad from the 10th generation onward, with USB-C, connects directly to GT and GT Max over the cable in the box, and Air 4 Pro connects the same way to tablets with USB-C video output. Older Lightning iPads, such as the 9th-generation iPad, follow the same Apple adapter and RayNeo HDMI Adapter chain as a Lightning iPhone.
Can GT or GT Max move between Pocket TV Pro and a laptop?
The cable that links GT or GT Max to the player links them just as easily to a laptop or tablet whose USB-C port carries DisplayPort video, since the glasses simply show whatever source is plugged in. Moving from a film on Pocket TV Pro to a document on a laptop means unplugging from one source and plugging into the other.
