It may someday be possible to listen to a favorite podcast or song without disturbing the people around you, even without wearing headphones. In a new advancement in audio engineering, a team of researchers led by Yun Jing, professor of acoustics in the Penn State College of Engineering, has precisely narrowed where sound is perceived by creating localized pockets of sound zones, called audible enclaves. In an enclave, a listener can hear sound, while others standing nearby cannot, even if the people are in an enclosed space, like a vehicle, or standing directly in front of the audio source.

I've found that bone conducting headphones work well for this. They are even secure enough for running and climbing.

Especially if you attach them to your mastoid with a couple wood screws.

You'll actually want to use metal screws, as wood screws don't conduct the ultrasonic waves as well, since they're not as stiff
