Hmmmm, think I'll wait till the price of the Epsom BT 300's comes down or DJI makes something that doesn't make you look like you're wearing a small building on your head.
I think you'll regret this decision the moment you try the dji goggles. There's nothing that comes close to the feature set of these goggles and price is not that bad. The head tracking looks spot on in the review I watched. You still have the option to use your phone or tablet with the controller in parallel to these goggles. Just flip them up when needed.
