The ADEL module was designed to protect your ears from pneumatic pressure. ADEL module has an open port. You will hear ambience similar to a semi-open headphone.
If I use my fingers to cover both ADEL self-tuning module ports, I get total seal/isolation.
There is a variable ADEL module (which will be provided later) where you can adjust the ambience or close the module. I don't think people buying ADEL will close it.
To my ears, A12 sound quality is very good with ADEL at semi-ambience.
As for my fit issue, right side CIEM trying to expand my ear. Thus, painful.
Can you comment on the difference in sound with the port open and with the port closed? I'm interested to find out how much improvement to the sound the ADEL module can provide.
