Apple’s AirPods Pro quickly rose to become one of the market’s most popular active noise cancellation-equipped wireless earbuds. Out of the box, they isolate users’ ears from their surroundings via active noise cancellation; and in the event that you need to hear somebody, they support transparency mode, which allows a person’s voice to pass through the AirPods Pro’s microphone and into the user’s ear canal as audio.
One thing worth noting is that when using the AirPods Pro, the user must manually switch between active noise cancelation mode and transparency mode with a gesture when either feature is desired. With that in mind, iOS developer Litten devised a way to make this behavior more autonomous based on the user’s circumstances, and as such, a newly released and free jailbreak tweak called Crystal was born.
