TF International Securities analyst Min-Chi Kuo, who specializes in Apple's supply chain, previously estimated the company sold somewhere between 160,000 to 180,000 Vision Pro headsets, based on preorder inventory and shipping time.

Kuo correctly predicted the headset would sell out soon after the release, citing a smaller shipment and the product's sky-high price tag. He later said that further scrutiny of the preorder shipping times, which had slipped initially but then held steady, suggested that demand for these devices had tailed off.

Kuo said the Vision Pro was still "a very niche product" for now and that demand for it would likely "quickly taper off" after die-hard fans had placed their orders.

Representatives for Apple did not immediately respond to a request for comment from Business Insider, made outside normal working hours.

The Vision Pro is Apple's first new product category since it announced the Apple Watch in 2014.

The device is a mixed-reality headset that aims to merge the user's virtual experience with their real-world surroundings. Early reviews of the headset have been largely positive, although the $3,500 price tag has raised eyebrows.

Apple is set to embark on its biggest hardware launch in a decade with the Vision Pro. Stores have been prepping for the launch for months, with free demos on offer for those who want to try out the tech.
