Just posted this in the ADEL thread:
Okay, so here's an update. I just called 1964ears and spoke to one of the guys there.
With regards to the ADEL technology, he said that the ambient port will let in outside noise when you open it up (and thus probably also leak sound, but he didn't specify that, that's my own interpretation). BUT, you can fully close it for full noise isolation, and doing so will still allow the ADEL technology to work, so it will still absorb part of the pneumatic pressure. So my understanding is that regardless of how you have the ambient port set, the ADEL stuff will work either way. Now that I'm typing this I realize I should have asked whether or not the noise isolation will be the same as a normal acrylic CIEM when the ambient port is fully clozed, just to clarify. Maybe someone else here can give them a call and find out
As for the tuning of the 10-driver and 12-driver models, he wasn't exactly sure yet how they would be tuned, but he expects one of them to have a 'natural' tuning, and the other to have a more 'bassier' tuning. He said that more details will be released soon on the kickstarter page.
Anyway, what he said about how the ADEL technology works has me much more interested now in these. I was about to pull the trigger on a JH13 today or tomorrow, but now I'll wait a few more days until more details have been released.
