I heard back from Cardo support fairly quickly, about a day after I submitted my question. They commented that wearing earplugs while using their units might be a problem (wish they told you that before you bought them) and suggested a factory reset. Rather than type it all again, I am pasting below their response to me and my reply back this morning with a couple issues I found. If any of you with PacktalkBold units are willing to replicate my experiement, I would be curious to know if you see a significant reduction in your FM radio volume when you fire up a second headset that is connected in DMC mode to your headset. That seems to be a significant part of our problem.
Here is the email conversation verbatim with my reply first and the original Cardo email at the bottom:
I did a factory reset on both units. I then paired each iphone to its respective helmet. I then turned on the FM radio and turned the volume to full. The volume was OK, but not all that loud. It was easy to hear without earplugs, but only OK with earplugs in. I also noticed that my wife’s unit will not tune to one of our favorite radio stations, 96.1. We have six preset stations and my wife’s unit tunes 5 of them OK, but gets mainly static on 96.1 whereas my unit tunes all six.
Here is where it got weird. With my FM radio playing at full volume, my wife turned on her headset. As soon as her headset was turned on, my headset FM radio volume dropped substantially, probably 30-50%, I’d say at least two levels of “Hey Cardo, volume down.” We waited 30 seconds or so and it stayed at that low volume. We then turned off my wife’s headset and nothing changed immediately, but about 10 seconds later the volume in my headset returned to normal. On subsequent tests I found that if I rolled the wheel forward after may wife’s headset was turned off, the volume would come back instantly without the 10 second wait.
Thinking that maybe the iphone connections were part of the problem, we turned off bluetooth on both phones to disconnect them. This made no difference.
Any suggestion as to what would cause this? After doing this, I remembered that last summer I seemed to have much better radio reception while riding my KLR650 alone than I do while riding my K1200LT with my wife. I thought that odd as the BMW is the quieter bike with its full fairing and large windshield. I think I now know the answer. The volume issue seems to come into play when the DMC intercom is connected to another headset.
Let me know what to try next. Or if I need to send the units back for warranty replacement. I am happy to make a video of this behavior and send it to you if that helps. I am sure the volume reduction will be audible on a recording as it is quite pronounced.

Wearing earplugs is probably part of the problem as they are designed to block out sound. Please try performing a factory reset on your devices and erase the pairings out of your phones. Then pair back together from fresh and see if the issues remain.
