DJI Goggles.
Do they work with the Phantom 3 Standard? What other goggle options are recommended?

Sorry, yet the DJI goggles are not compatible with the P3S. There are other companys that make goggles that are compatible with the P3S, a quick google search will pull up a bunch of options. You could also try youtube for reviews.

Hi, Sorry that the DJI Goggles is not compatible with the P3S. DJI Goggles supports Mavic series, Spark, Phantom 4 series and Inspire series. Some functions will be adapted for different DJI Products. Please don't hesitate to reach us if you have other concerns. Thank you for the support.

You can use the DJI Goggles if you connect them to a mobile device that has an HDMI output (like the Nvidia Shield K1).

After doing some research I haven’t found much. Does anyone know any specific goggles that work?

You can use any goggles that can be connected to your mobile device via an HDMI output. That of course means you'll need to first find a mobile device that has an HDMI output. That's the best way to use googles with the Phantom 3 Standard.

I have an iPhone. There is not an HDMI port but would it work to get a cord that has USB on one end and HDMI on the other?

The lightning wire from the iPhone to the DJI´s goggle ?? I don´t know how it should convert the lightning data in to HDMI signal. And Bluetooth is too slow for that data volume.

There is a company called fatsharks that makes goggles. Here is a video of how to connect them to your drone.

You can connect the HDMI cable that comes with the DJI Goggles to the Apple AV adapter (see the photo below). That will allow you to mirror the display from your iPhone on the DJI Goggles screen. You could then swipe up on the screen in DJI GO to switch to full screen mode. While this won't allow you to use all of the features that are available inside of the DJI Goggles (like when flying a Phantom 4), it will allow the DJI Goggles to act as a second display.

Fatsharks are well known goggles used for race copters because they don´t have any delay.
