While Mark Zuckerberg and Meta press forward with augmented glasses projects buoyed by its million-selling set of smart Ray-Bans, Bloomberg reporter Mark Gurman says that Apple just pulled the plug on an AR glasses project. Codenamed N107, they’re described as something that would’ve looked similar to regular glasses but with added displays in the lenses that could connect to a Mac.

With features that sound similar to devices like the Xreal One AR glasses, the glasses could’ve delivered on the Vision Pro feature that’s closest to being any kind of a killer app (popping up a huge virtual monitor anywhere) without the $3,499 price and heavy design that required a head strap. The glasses also would’ve had tint-changing lenses that, like the Vision Pro’s Eye Sight, could signal to onlookers whether the wearer was busy or not. While other details are fuzzy, it doesn’t appear as if the N107 glasses would’ve had a camera or any of the mixed-reality features of the Vision Pro.

A big problem, according to Gurman, was developing something that worked well while being cost-effective proved to be a challenge. Apple initially wanted the N107 to connect to an iPhone, but it proved to be a battery-guzzler, and the iPhone itself didn’t have enough juice to power the glasses — hence the shift to a Mac. Unfortunately, that switch purportedly didn’t seem to go over well with executives in testing.

This most recent cancellation puts a big question mark over Apple’s future AR and XR plans. Apple purportedly canceled a separate AR glasses project in 2023, and rumor has it that work on a Vision Pro 2 has been put on hold in favor of trying to create a cheaper Vision Pro. Meanwhile, the Vision Pro itself has struggled to find a foothold.
