The Apple AirPods Pro charging case may soon be made more user-friendly. 

Ming-Chi Kuo, an analyst at the Wuhan-headquartered TF International Securities Group Ltd., tweeted Friday in response to a developer who reportedly caught references to new AirPods models in Apple's iOS 16.4 software. 

"I think this is likely the USB-C version of the AirPods Pro 2, with mass shipments expected in 2Q23-3Q23. By the way, Apple currently appears to have no plans for USB-C versions of the AirPods 2 & 3," Kuo said, quote-tweeting user @aaronp613. 

The current AirPods Pro case requires a Lightning cable to charge the wireless headphones.

Apple did not immediately respond to Fox News Digital's request for comment on the matter.

The AirPods have been refreshed a couple of times since the tech giant launched them in 2016. 

The AirPods Pro was first released in 2019 and a second-generation version was released just last year.

It remained unclear whether Apple plans to add more features — including hardware alterations — to the case.
