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.
