Headphone : What is it?
Headphones allow you to listen to recordings privately, without disturbing others. They are ‘transducers’ that receive electrical signals from the media player or receiver with speakers that held closed to the ears that convert the electrical signal into sound waves. Headphones are connected to audio players (like MP3 players, stereos, CD players, etc.) by jacks. Each earpiece has a speaker that transforms electrical signals from the audio players into perceptible sound waves. There are six types of headphones: closed, open, ear pad, behind the ear, in-ear, and voice types.
Kinds of Headphones include the following:
Closed headphones are also known as isolating and closed back headphones. They eliminate outside sound and seal in inside sound. They are ideal for noisy situations, as they cover the ears entirely.
However, closed headphones have difficulty producing bass frequencies, as the sound seals are affected by hair, eyeglasses, and head pressure. They are available in corded and wireless models. Some types are called circumaural headphones because the earpieces look like giant cans.
Ear pad headphones
Ear pad headphones are also called supra-aural headphones. They are similar to the closed types but cover only the top of the ears. They are smaller yet offer only a slight diminished sound quality due to their size.
Open headphones are also called open back, open air, or vented headphones. They allow some outside sound to penetrate the ears, eliminating some ear pressure.
Open headphones are ideal for recording songs and for musicians who want to hear environmental sounds. Some models have twin damping systems for faster bass responses.
Voice headphones are used for accurate voice reproduction. They are commonly used in language labs, intercoms, and voice communication applications.
In-ear headphones are made with ear buds placed in each ear canal, making them almost invisible. They offer outside sound sealing. Some in-ear headphones can have transparent plastic tubes that clip behind the ear and earmolds that fit in each ear canal. They are ideal for performers and television artists who want to conceal their headphones from the cameras.
These types of headphones are also known as earclip headphones. They are worn behind the ears using ear clips. They can be used as sports headphones while running, jogging, or participating in sports-related activities.
|Earpieces: Choose headphones with rotating earpieces that allow you to twist them aside, letting another person listen to the music without removing them. |
Foldability: For portability, look for headphones that easily collapse and fold, allowing them to fit easily in your purse, bag, or backpack without taking up too much pace.
Compatibility: Look for headphones with a headphone jack compatible with your audio player. Consult your audio player’s manual for the required headphone type.
