I'm not sure if a membrane can be utilized in an adjustable valve. For one thing, the ADEL featured silicone tips expands to relieve pressure from the iem cavity, while maintaining a sealed ear canal but as a result the ADEL causes a reduction in spl of lower frequencies and no ambient noise to enter.
Plus I found out that the $100 dollar earphone on the launch website is in fact produced by Asius Technologies. Not sure about the 200 dollar model though.
EDIT: Turns out I have not read the entire page in detail and did not read the section where both 1964 and Asius have collaborated. My bad.
I did note that the 1964 name is not even applied to the lesser two IEMs - only the custom/universal versions of the V series IEMs....
