I definitely like headphones over earbuds
Same! are a pair of small loudspeaker drivers worn on or around the head
I use to rock out with huge headphones and my discman.  LOL
i have heard  They are electroacoustic transducers, which convert an electrical signal to a certain sound.
That's really cool.  Do you know when they were first invented?
im not sure but Headphones let a single user listen to an audio source privately.
