Fejhallgatókhoz, commonly referred to as headphones in English, are audio output devices that are worn over or in the ears. They are designed to allow a single user to listen to audio signals without disturbing others nearby. The primary function of headphones is to convert electrical signals from an audio source, such as a smartphone, computer, or music player, into sound waves that can be perceived by the human ear.

There are several main types of headphones, distinguished by their design and how they fit the ear. Over-ear headphones, also known as circumaural headphones, fully enclose the ear. On-ear headphones, or supra-aural headphones, rest directly on the ear. In-ear headphones, or earbuds, are inserted into the ear canal. Each type offers different levels of comfort, sound isolation, and audio quality.

Headphones utilize drivers, which are small electroacoustic transducers, to produce sound. These drivers can be of various types, including dynamic, balanced armature, and planar magnetic, each with its own characteristics affecting the sound reproduction. Connectivity options typically include wired connections, using a standard audio jack like 3.5mm or USB, and wireless connections, most commonly via Bluetooth technology.

The use of headphones is widespread across many applications, including personal listening to music, podcasts, and audiobooks, as well as in professional settings like audio engineering, broadcasting, and gaming. They are essential tools for enjoying private audio experiences and for critical listening in various professional fields.
