  Welcome to the dark side my friend. For in U12 you shall find utter darkness.

What modules are you using with your A12's

I alternate between B1 and G1.

ADEL contains the proprietary membrane that absorbs pneumatic pressure generated when an IEM is sealed inside the ear. APEX is just a vented design. 

 
The end result is the same as far as ear protection goes.  Sound quality is another story.

My m15 vs m20 mini-review here: http://www.head-fi.org/t/739712/1964-ears-adel-iems/7515#post_13164605

Nice review.  I agree 100% in your findings.
Thanks!

Not true. You should probably read up on this as hearing damage due to iems is more complex than simply listening too loud.

I think the B1 and G1 is similar to the M20 and M15.  I was convinced that the ADEL had to be better until I got my new A12's and tried all modules. ADEL and APEX.  When I popped in the M15 I was blown away.

You my friend should do more research on this. Pressure relief is simply pressure relief no matter how you accomplish it.  Physics doesn't change by the technology you use.

My belief is that A1 and M20 are probably closer. And G1 and M15. What does everyone else say?

I have been in this business for over 30 years and can tell you that both technology's relief in ear pressure equally.  One acts like a bottom drum head and the other acts like a vent.  Both do the same thing just in different ways.  I like most here, happen to like the vented version.
Sorry!

Agree except Not the A1 But the B1

I thought the m20 was similar to S1 and the m15 was similar to the B1.

You are correct.

You are correct.

I have the B1 and m20 and prefer the B1. I would like to try the m15 but need another 50% off sale to try it.

I bet you ask for it you would get it.  64 audio will go out of their way to help you.

That was something I never considered.

Worth a try. After all they are one of the best IEM / CIEM companies on the planet.
