The original XREAL Beam (not the newer Beam Pro with its display and far wider reach for application support) is a useful, if frustratingly limited companion to the company's glasses. If your primary use of something like the XREAL Air 2 Pro glasses is with a PC or a gaming handheld like the ROG Ally, you probably don't need one.
But if you want to use your glasses as your own private cinema, it's useful to have. By using the Beam, you don't need to rely on your smartphone or laptop to deliver the latest hot Netflix show, instead you can push it from the pocket-sized Beam straight to your eyeballs.
