Is there a such thing as a headphone (not music) that

Sort of like a high tech ear plug.

I am looking to quiet down white noise, motor noise,
television, folks talking. And yes all at the same
time.

I googled, but am only finding music head phones.

You are looking for hearing protectors. There are some very good ones
designed for the shooting sports that are adjustable to allow normal
conversation but block out louder noises and can be tuned to completely
block all sounds.
