I have gotten a few messages from people that this has worked for. When I started diving I could not clear my ears the regular way of plugging my nose and blowing. What worked for me was when I felt the pressure I would exhale into my mask increasing the air density. This for some reason would allow me to swallow. Thus poping my ears. Without exhaling through my nose in my mask I could not swallow, well I still could swallow but there was no poping in my ears. Hope this helps for the people who can not equalize the regular way like myself.
