Clear water clogged ears with the iPhone

I wish that I had discovered this earlier. The iPhone’s speaker can clear water clogged ears.
iPhone 4 speaker
My ear was blocked by some water after a shower and I went outside for a walk afterwards with Zombies, Run! running on my iPhone. I held the speaker of the phone up to my ear, about 1 cm away, to hear one of the voiceovers and the dome of water plugging up the ear broke down.

My best guess is that the cohesion of water in the ear was weakened by the varying frequencies of longitudinal waves emitted from the iPhone. The speaking voice from the voiceover in Zombies, Run! varied from low to high frequency at a regular rate and further helped the breakdown of water dome in the ear.
