^ go, or stop? Not good news
These poll figures - supposing they are approximately representative - are strange. It's hard to explain the progression of 1, 2 and 3 failures with a single factor model although there are complicating issues.
For example, suppose probability of failure is 30% (and due to a single factor which strikes absolutely randomly). This makes a nice simple model. Then, probability of a 2nd failure for the same person is 0.3 x 0.3 = 0.09 = 9%; a 3rd is 0.3 x 0.3 x 0.3 = 2.7% and so on.
Actually the pattern of predicted failure will likely be less than 30, 9 and 2.7% assuming some people give up after 1 failure; some again after 2 and so on. At each step this reduces the pool of people who are
able to experience multiple failures.
The fact the poll shows much higher figures for 2nd and 3rd failures than this model predicts suggests
if an owner experiences one failure they are more likely to experience further failures. That's strange.
Here are two possibilities off the top of my head:
1. Audez'e don't generally replace with a new pair. Instead they fix the returned pair but the fix does not return the headphone to "good as new" condition. The probability of failure is higher than with a brand new pair selected at random. This would mean the true cause of the failure is not fully and reliably addressed by Audez'e's repair method
2. There is some factor in the owner's environment to which the LCD3 drivers are vulnerable. The fixed pair is as good as new but has a high probability of failing again because the factor in the owner's environment is still present. Obviously this would mean Audez'e has failed to identify this environmental factor. Btw, I do
not mean to suggest this hypothetical factor is the owner's fault!
I'm sure there are other possibilities, not to mention that several causes might be involved
