Because the muscles that we use to move ears are used by other animals to help with detecting interesting sounds (like when you see a dog's ears twitch when they hear something). Since those muscles aren't serving our bodies in that sense, and we really only use those muscles to wiggle ears for fun, they can be considered vestigial (ie. present in our bodies, but not really doing anything: like our tailbone, or our appendix)

Why muscles that move ear vestigial?
Humans do not need to move their ears to hear, but those muscles have nothing to do with hearing sound (there are muscles in the middle ear which do) BUT with the location of sound. The shape of the human ear is a type of phase-delay echo chamber; this phase delay gives us an up-down orientation to a sound. The phase difference of the sound from each ear gives us right-left orientation. This method is much quicker than turning either the ears OR the head to locate a sound source.

What is the function of the ear muscles?
The muscles of the external area of the ears are vestigial structures which were once useful, but through evolution have lost their usefulness. Monkeys can be seen using these muscles around the ear(s) so that they may better locate a potential predator in the vicinity; moving the ear(s) in different directions. Muscles in the middle ear are mostly used to protect against loud noises, as is the Tensor Tympani muscle. The stadepius is the smallest skeletal muscle in the body, and is used to stabilize the stapes, the smallest bone in the body.
