Whipbull reported that on February 24, according to foreign news reports, a small number of Apple Vision Pro users claimed that their headphones had a thin crack in the middle of the front cover glass, although they were never dropped or mishandled.
The first report was published in the Reddit R VisionPro subreddit about 18 days ago, and several more have appeared in the last week. All images show a distinctly similar vertical hairline crack above the bridge of the nose, meaning that the damage occurred at a specific point of tension, where the curvature of the laminated glass is most pronounced.
We couldn't find more reports like this on social media, the Apple support community, or the MacRumors forum, suggesting that this is most likely a manufacturing defect limited to low-volume devices rather than a widespread issue.
These reports all mention that after the earphones were connected to an external battery pack and stored overnight with a soft front cover attached (some in Apple's travel case), the cracks suddenly appeared for no apparent reason.
One theory is that the crack is caused by the pressure exerted on the glass when the strap is tightened, which causes the surrounding frame to bend. Others speculate that the problem may be due to an overheating issue that causes the glass to expand and cause its weakest point to break. Given that the battery is located outside the headphones, any heat generated may be caused by a runaway background software process.
Apple's documentation states that the Apple Vision Pro continues to draw power from the battery pack when not in use, allowing the device to sync mail,** and other data. If you don't wear your headphones for 24 hours, Vision Pro will automatically power off.
With Applecare, the deductible for cover glass repairs is $300. Without AppleCare coverage, the same repair would cost $800. Some affected owners said they had contacted Apple support and were asked to pay for repairs because the cracks had not yet been officially identified as manufacturing defects.
