The difference between listening to music using speakers or a headphone is striking.


When listening to speakers:

When listening to a headphone, each ear will receive 1 and 1 channel only. No mixing, no delay, no indirect sound coming from the surfaces of the room.

It is possible to mimic listening to speakers over a headphone by using a crossfeed.

Heaphones can by ocer the ear, on erar, in ear, see types.

The dynamic driver is common but there are other drivers as well.
