Apple has just announced the beta version of their new firmware update for the AirPods Pro 2. The new firmware, codenamed "7B5013c," includes various improvements to the device's functionality and design.

One of the key updates in this firmware is the addition of an助听器 feature that allows users to hear better while wearing the device. This feature uses advanced noise-cancellation technology to isolate the sound waves from external noise, allowing you to focus on your surroundings without distractions.

In addition to the new助听器 feature, the firmware also includes improvements to the device's transparency mode, which allows users to see through the earbuds when listening to music or other sounds. This can be particularly useful for people who suffer from hearing loss or who want to have a more natural sound experience.
The developers will now have the opportunity to test and provide feedback on the new firmware. They can submit any bugs they encounter, as well as suggestions for improvements to the overall user experience.
Overall, the new firmware update for the AirPods Pro 2 represents a significant step forward for the device. With the added features of an assistive hearing aid and improved transparency mode, the AirPods Pro 2 has become even more versatile and customizable. We look forward to seeing what else Apple has in store for us in the coming months.
