Wow.....what a DB
I did not follow Quero's links but I have read reviews on SB from a couple people that made the claim that it helped with their equalization issues (FWIW of course).

I bought one of these masks a few years ago because I was diving in a lake with known bacterial problems. They are superb for keeping the ears dry, but don't necessarily make equalization any easier.
The ear cup MUST seal around the ears, just like the silicone of the mask must seal around the face. I had no problem (shaved head), but my dive buddy couldn't get the to seal. I purchased the specially made hood, which helped her seal the ear cups.
