I had the same crackling sound issue on the left piece and a buzzing sound in the right piece. I have spent a crazy amount of time with apple support over the last 3 months on this issue and finally decided to take the AirPods Pro to the Apple store.
Visited the Genius Bar yesterday after a 1 hour drive. After waiting for 2 hours in queue, they did some basic test and decided to replace both the left and the right Airpods Pro pieces. To my surprise, the firmware of the replaced left earpiece (2B584) was different from that of the right earpiece (2B588) and simply the airpods were not usable together the whole of yesterday. Again had to spent an additional 1 hour with apple support, then followed the steps given in my previous post to sync up the mismatched firmware versions to the latest firmware version (2D27).
Today is my second day with the replaced Airpods pro. The crackling and the buzzing sound, touch wood, has not reoccurred till time.
While am happy that my replaced AirPods Pro is finally usable...have a lot of questions and doubts which are unanswered....
1 - Is the issue a generic hardware issue or a software issue?
Basically, have this question as I did not get a chance to check if installing 2D27 solved the the crackling sound in my old problematic Airpods pro. The version of the old problematic AirPods Pro was 2D15 at the time of replacement and apple does not give any control for its consumers to directly initiate the firmware update for Airpods.
2 - Will the crackling & buzzing sound reoccur on the replaced AirPods Pro after some time of usage ?
Have started using my replaced AirPods Pro very frequently since I replaced it yesterday. Am worried that this problem will start after the warranty period....and so I want to find out sooner, if it re occurs again, at least within the warranty period....so that I can have it replaced again.
3 - If the answer to my 1st question is that the AirPods Pro has a generic “Hardware Issue”.....Is Apple ready to consider a recall and replacemeant of problematic AirPods Pro beyond the warranty period?
In such similar situations in that past, apple has extended the warranty of some of its faulty products beyond the normal warranty date of the product. They extended replacement of Apple Watch series 1 beyond 3 years for a generic battery issue which caused the Apple Watch series 1’s back cover to pop out. So the question is...will apple take a similar stance for the faulty Airpods Pro design ? (Although it Is not conclusive that this Issue is a hardware design issue, due to lack of communication from apple regarding this specific issue)
I strongly feel apple should beef up its communication on the faulty Airpods pro “Crackling & Buzzing sound Issue” and extend warranty for its faithful customers who are a victim of this situation especially due to the following reasons !!
A - Given the fact that this particular issue is so much widespread
B - People have spent so much time with Apple’s support and Genius Bar
C - The AirPods Pro is not a cheap piece of device that customer have to go through this trauma.
Apple, you need to talk more on what is going on here !
