Great questions, glad you like the review.
Noise Isolation. They are rated for 26dB's of isolation, and I am not gonna question that. I find that I have been yelled at through my house for a few minutes before I notice someone at my door because I didnt hear them, even when i just had the AS-2's in and was looking for the right song, so they weren't plugged in yet.
Leak of sound? Not at all. I asked a coworker of mine to tell me if he heard anything as I turned my volume up. It reached the point where I didnt feel comfortable turning it any louder because of it being a lot higher than my normal comfort listening level and they still did not hear anything. This is also dependent on if you open the bass port or the ambient port (if you get one on your pair of AS-2's).
I am more than satisfied with the software based bass boost. I don't like touching things that if i can't get it back to 100% perfect how it was then I will be annoyed when I listen to them. Fear is mainly no way of knowing how open or closed they came and if I turn one ear i gotta attempt to turn the other ear equal amounts to have them tuned right (i think). Way too many variables and I honestly don't care if I never try them out, I know Dale and Aurisonics did an amazing job with them and I enjoy them how they were intended to be heard from factory. The ZO2 though can boost the bass ridiculous amounts. I have made my head uncontrollably rattle by using the bass boost. I literally could not control my head enough to stop it from shaking around and the entire time I heard the midrange and treble as clear as without the ZO2 and the bass was just cleanly and amazingly giving me the feeling of being in front of a huge subwoofer. Lots of fun, not advisable for long periods. I did this for maybe 5-10 minutes tops on a few occasions just to have some fun with it and test out how well the AS-2's could scale. It's really hard to notice any change in quality of the other ranges when you boost the bass, and that's what I wanted to find out, so mission accomplished.

Its too bad you don't want to mess with the bass ports because I'm sure a lot of people are interested in how they affect the sound, but its your IEM so its your choice. Do you feel like once you open them, you won't be able to return them back to how they were set? Can you get any feel for how open they are when Dale sends them out? I guess I'm just surprised that curiosity didn't get the better of you, especially when you could compare that natural bass boost to the zo2's software bass boost.
How's the noise isolation?
Do they leak a lot of sound?
Yes, sometimes I forget the mantra too. It's easy to do that once you got the AS-2's though. At least in the CIEM department. I've grown to want better sources and amplifiers and audio files since I got the AS-2's. They are uber revealing and it's magical to hear some great vocals on them and all the other qualities that add so much depth to the music you listen to. I went to a concert on June 23rd where I saw an artist I like a lot, and I can tell you that I have been able to feel like I am still there ever since, just because I have the AS-2's. They truly handle 3D imaging and the soundstage amazingly well and beautifully done in a neat packaging that fits my ears perfectly.
