To me the bass is not better enough with bi-flanges to justify the convenience drawbacks comparing to single flanges. I noticed that dynamic earphones with wide inner tube don't benefit from better seal in terms of bass weight. The tips affect the bass quality rather than quantity. Stiffer tips produce tighter, faster and deeper bass. UE single-flanges are stiff enough to produce the excellent bass and are convenient.
I just thought - may bi-flanges produce deeper bass? I'll check soon.

I am thinking on review revision now. I'm too lazy to make these detailed comparos again.
