Apple has posted a recall on its site regarding the static sound issue with AirPods pro. I also heard annoying noise when making a phone call with ANC and Transparency modes turned on in my headset. It was replaced for the second time under warranty. I found out that this problem is on devices with hardware version 1.0 and it is fixed in 1.1.
My exchanged product arrived last week. The hardware version was still 1.0. There was no static sound issue when I first put on the headphones. Especially when the transparency mode is turned on, you forget that you even have headphones in your ear after a while. It is that successful. The software version of the incoming product was outdated. That night I put my phone and headset on and left them on charge. The next morning, interestingly, I felt as if there was pressure when the headset was in my ear. The product, which I said you would forget that you even had headphones in your ear after a while the previous day, caused discomfort in my ear all day because of that pressure sensation. When I checked the software version I saw it was updated. The spirtual sound feature had already come.
Currently there is no static sound issue. It just felt like there was a slight decrease in the bass, but I wasn't sure because I couldn't compare it with the previous one. The previous static audio problem also appeared after a while. I'm worried that it will happen again. Fortunately, the product is still under warranty and Apple is good at service.
However, although it is written on the internet that this problem is fixed in 1.1, I do not understand why the new product that came to me came to 1.0.
