If it's the same thing I can do, it's very useful. I can "pop" my ears voluntarily, which is nice when freediving.

... and when flying! (normally, I mean)

Just thinking about it now ... I kinda pull my jaw back a bit and push my tongue against the back of my throat, like the first half second of a swallowing action. It's enough to make a little 'click' in my hearing, even when I've not changed altitude.

I can pop my ears by plugging my nose and making a "k" or "g" sound. Comes in handy since my Eustachian tubes are essentially useless.

What I described above is called a BTV. This sounds like a Frenzel, which is the one most experienced freedivers use. https://en.m.wikipedia.org/wiki/Ear_clearing

Huh, I thought this was the val salva maneuver.
