Earphone

 

a miniature device for listening to dictaphone and magnetic tape recordings, radio broadcasts, and the simultaneous translation of speeches. Earphones are similar in purpose to headphones. They contain one or two miniature electromagnetic or piezoelectric transducers, which convert electrical oscillations into an acoustic signal, and extensible acoustic conductors; the latter are connected to the transducers and have plastic tips that are placed in the ear. Unlike headphones, earphones do not have a headband that grasps the upper part of the head and are therefore more convenient to use.

earphones

Small headphones in each ear. Also called "earbuds," earphones stay put by resting inside the ear or by being inserted slightly into the ear canal or with hooks that wrap around the ear. Another variation is an earphone that clips onto the earlobe.

Ear Monitors
High-quality earphones called "ear monitors" have been used by performers on stage to hear instruments as well as cues. They are also available with custom-molded inserts like hearing aids and may be called "custom in ear monitors" (CIEMs). See headphones, headset, EarPods, AirPods, air tube headset and mini-phone connector.


Stock Earbuds
Earbuds like these come standard with music players and smartphones. Although providing decent sound quality, higher-end earphones and especially headphones offer a better audio experience.
