No input sound is microphone output sound is speaker
That depends on the sort of microphone you have. A condenser microphone gives 20 dB more output level than a dynamic microphone.
No.
NO
Input, because a microphone can capable of detecting sound.

If they are for hearing then its output device as they are not putting anything in to the computer, if they have a microphone attached as well then they are input/output (i.e. microphone is input, speakers are output)
Microphones do not output anything, they are INPUT devices.
Microphone converts Audible Sound into digital signals that's why it will be considered as an INPUT device not an Output device.
A microphone has a voltage output and an acoustical input. Only the sound wave can move the diaphragm of the microphone and a voltage signal comes out. That goes to to an amplifier and to a loudspeaker.
A microphone is a source that sends an output to its male plug. A loudspeaker is a load and receives an input at its female plug.
After testing it, i found that at least with simple earbuds, you will just hear clicking when you plug the headphones in. There are no practical uses of plugging headphones (output) into a microphone port (input).
