Apple AirPods: Similar to the ears they live in, AirPods Pro are usually sold in pairs. One is located in the left ear, whereas the other is in the right. It has always been like way. Nonetheless, it's not unusual to see someone with only one earbud on. Perhaps that's just the way they operate. Perhaps they want to keep one ear free and need to ensure that they can hear what is going on around them. Alternatively, it could be that they only have one ear. However, the truth is that you don't require an explanation.
To activate this feature, simply follow these easy instructions. Link the AirPods Pro to your iPad or iPhone. Go to Settings. Select AirPods by tapping on Accessibility. Turn on the "Noise Cancellation with One AirPod" switch under "Noise Control." and that's it.
You may now just press and hold the force sensor on the AirPod you wish to silence whenever you need some quiet time. As per usual, a short touch switches between ANC, transparency, and off.
