Best Headphones

Headphones (or headphones in the early days of telephony and radio) are a pair of small listening devices that are designed to be worn on or over the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound in the user's ear.

Headphones are designed to allow the user to listen to the sound of the sound. Headphones are also known as earspeakers, earphones gold, colloquially, cans. Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place.

The other type, known as earbuds or earphones consist of individual units that plug into the user's ear canal. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones audio, radio, CD player, portable media player, mobile phone, video game console, or electronic musical instrument, either directly using a cord, or using wireless technology such as bluetooth or FM radio.

The first headphones were developed in the late 1800s from telephone receivers, to keep their hands free. Initially the audio quality was mediocre and a step forward was the invention of high fidelity headphones.

Home theater, personal computers, or portable devices (e.g., digital audio player / mp3 player, mobile phone). Cordless headphones are not connected to their source by a cable.

Instead, they receive a radio or infrared signal encoded using a radio or infrared transmission link, such as FM, Bluetooth or Wi-Fi. These are powered receiver systems, of which the headphone is only a component. Cordless headphones are used with such silent discs.

Headphone size can affect the balance between fidelity and portability. Generally, headphone form factors can be divided into four separate categories: circumaural (over-ear), supra-aural (on-ear), earbud and in-ear.

Circumaural

Circumaural headphones have circular or ellipsoid earpads that encompass the ears. Because these headphones completely surround the ear, circumaural headphones can be designed to fully seal against the head to attenuate external noise.

Because of their size, circumaural headphones can be heavy and there are some sets that weigh over 500 grams (1 lb). Ergonomic headband and earpad design is required to reduce discomfort resulting from weight. These are commonly used by drummers in recording.

Supra-aural

Supra-aural headphones have pads that press against the ears, rather than around them. They were commonly bundled with personal stereos during the 1980s. This type of headphones, resulting in less attenuation of outside noise.

Supra-aural headphones can also lead to discomfort due to the pressure on the ear as compared to circumaural headphones that sit around the ear. Comfort may vary due to earcup material.
