I have had the Meelec dual flanges for a couple days now and have some brief impressions. I wont go into detail about the baseline ASG1 sound as that has arlready been done very well by many other members. I will talk more about fit, comfort and aesthetics with ears that arent prefectly shaped for the ASG1s
In my ears the tips gave a deep insertion. The clarity and airiness were slightly improved as well as taming the sometimes shrill upper midrange. This was great, except for the fact that the ASG1s now sit very far out of my ear, nowhere close to flush. This feels very awkward, as it seems like the only thing holding them in my ear are the tips. Even though they are secure, when being active, they felt like they are about to fall out.
I know this will not apply to everyone, I just thought I would mention this for people who have ears that dont allow the ASG1's to sit flush even with the single flange. Here are some pics:
