I am not aware of any damage being caused by the A70 Pro headphones.Earlier in this thread, in fact. Page 32 I think? There's a posted video that shows the popping and a follow up post from the same user mentioned that the driver wasn't the same afterward. There's a few other anecdotal reports that I had but I've sadly lost them amongst the hundreds of tabs I had open while researching into this.
Ahh, my bad about the volume control, I used the wrong terminology. I really meant "not potentiometer based" as that's the current issue I have with my 789.
And hmm, well, I may just bite the bullet and give it a shot. Here's a question for you, as you seem to be the most knowledgeable about why these things might be failing: is there any legitimacy in assuming that, once a certain threshold is crossed, that one could rule out their particular unit as being affected by the potting compound issue? If I ran this thing for 500 or 1000 hours, and it didn't show signs of an error, could I reasonably assume this particular error won't crop up on my unit? (The number is obviously arbitrary and only an example, I am aware that we don't have a specific figure to shoot for here.)
I'm mostly just concerned about it doing something abnormal to my headphones, or my hearing for that matter.
When it comes to loud noises, I am always very cautious about blaming a device because there are often several circumstances that can lead to it. You are always on the safe side if you stop the music and unplug the headphones before changing anything.
I can only estimate this based on my experience with the PA5; after 1000-1500 hours it is unlikely, and I have not had any defects with the encapsulated modules over 3000 hours.
