In the same way those swirly Youtube spirals make the world melty for a bit after you look away, or staring at a negative colour image briefly the black and white verson briefly appear to be in real colour, your ears become acustomed to the tones in the razor’s buzz.

When you turn off the razor and run the water, your brain hears the water minus the buzz tones, which sounds weird to us.
