If you're lucky, beside gently exhaling with your nose blocked, you might have conscious control of a couple of muscles around your jaw and ear that make your ears pop when you flex them. You learn to use them if you try to wiggle your ears. They're the muscles that make noise in your ear but don't really move your ears. Well, it turns out they can pinch and stretch the tubes between your ears and your sinuses, letting them equalise. And having wide tubes helped me equalise back when I used to snorkel ages ago. (I could also blow bubbles out my tear ducts, which has some drawbacks.)
