Hi guys
 
I'm posting this here - rather than the APEX thread as I didn't want to take things there off-topic (not fair/ethical for 64Audio given the split).  But I did want to correct some misinformation on open vs closed systems - so I contacted Stephen Ambrose yesterday and received the followimng information.
 
  All ADEL embodiments (both inflatable and passive) incorporate the use of our patented pneumatically compliant membranes. These membranes are all manufactured to special  Gurley Number specifications which regulate porosity based on the performance characteristics of each specific model:

PorosityEdit


The Gurley second or Gurley unit is a unit describing the number of seconds required for 100 cubic centimeters (1 deciliter) of air to pass through 1.0 square inch of a given material at a pressure differential of 4.88 inches of water (0.176 psi)(ISO 5636-5:2003).[1]

https://en.m.wikipedia.org/wiki/Gurley_Precision_Instruments

Unlike the apex vent/filter which is always open, ADEL membranes are selectively open at higher pressures and completely sealed at lower. This allows for overall equalization of higher in-ear device insertion pressures while affording a complete seal for acoustic pressures which are variably stripped of their pneumatic components with minimal leaking of acoustic components. 

This is an actual scientific breakthrough in preventing hearing loss which has been funded, researched and confirmed under various NSF, NIH, and Vanderbilt University grants - which 64 is attempting to attribute to their "research" (which they contracted NOT to pursue) and their "me too" apex technology.

Vents and filters are not new or patentable and relieve pneumatic pressures simply by leaking them to the outside environment and also allow environmental sound back in. 

Being pneumatically compliant, ADEL membranes mitigate pneumatic pressures while maintaining the acoustic seal and can allow for adjustable impedance matching of both in-ear as well as external sound pressure levels. External sounds must match the impedance of the untensioned membrane to pass through freely.

Blowing pressure through a B1 module can exceed it's Gurley specification and intentionally pass enough air to silently equalize in-ear pressures with external ones in a manner similar to equalizing middle ear and external pressures through opening the Eustachian tube and "popping" your ears while at lower acoustic pressures, the membrane is designed to be impermeable.

Thanks for this great reply Paul, appreciate it. :)

Less than two days left to participate the in the Indiegogo ADEL™ Drum Earbud campaign. Click here for information on how you can participate in the campaign.

@Canyon Runner 
Not sure if this is the right place to ask, but here goes. Is Asius planning on expanding their cooperation with IEM companies? Will ADEL modules be provided to other IEM companies? So far its just Empire Ears and 64 Audio, right? Is there a chance we will see other IEM manufacturers like Unique Melody, JH Audio, and UE acquire ADEL modules? 
Also, will Asius technologies have a booth/exhibit for those that are interested to interact with their technology/representatives directly at Can Jam? Specifically, the So Cal Can Jam during April this year. Would really love to meet the team behind all this tech, if not then I'll just plod over to Empire Ears to taste some of that juicy ADEL. Thanks for your time!

Hey man, for CanJam SoCal specifically (at least as far as I know) we'll be with Empire at their booth.
 
As far as other companies go, we're talking to a few but nothing is locked down yet (first of the year being right around the corner and all).

Thanks for letting me know! I'll see you guys there. I'll be dreaming every night of the other flagship IEMs getting their ADEL modules. Will there be new releases at CES? Or are you guys saving all the goodies for the Can Jams?

You'll just have to wait and see!

any update on the adel line and sound signatures, did you manage to finalize the tuning of the higher perks iems

The thing with that is it's so user tunable that it's really down to what the user whats to do. There is no defined sound signature, that's why I haven't been posting about it. It's designed to let you do whatever you want with it, in terms of sound.

Cool.

@Canyon Runner I had a quick question. When traveling, I've read that an effective way to maximize passive noise cancellation is ti use IEMs underneath over ear hearing protection (provided you don't think it looks too dorky). Considering the ADEL tech,would it be correct to say that this would defeat the pressure equalization benefits that ADEL provides, or am I mistaken?
 
Thanks in advance for your help.

What kind of over ear protection do you have in mind? Generally speaking, over ears do not provide an airtight seal, so I would see no issue with that.
