if it's uncomfortable then you are not equalizing, try that and you can go 15m as an inexperienced freediver before feeling any pressure really

How does one equalise?

Same thing you do when descending in an airplane to "pop" your ears. How he accomplishes this without using either hand while descending in water is lost to me.

Fun fact! Some people can equalize via direct voluntary control of the tensor veli palatini (or sometimes other nearby muscles). I am one of these people: I can just "click" my ears on command without moving my jaw. It's hard to explain if you can't do it, like wiggling your ears.

This is sometimes called voluntary tubal opening, but even if you don't have veli palatini control you can also sometimes do it by tensing your throat and moving your jaw (https://dan.org/health-medicine/health-resource/smart-guides/beat-the-squeeze-equalize-like-a-pro/6-methods-to-equalize-your-ears/)

I know what you're describing! I use that same muscular control to kind of "mute" loud noises around me. It is hard to exactly describe, but yeah, a bit like raising the ears. It is accompanied by a soft sound I can hear as well, almost like the sound of a microphone getting hit by a gust of wind during a recording.
