Please help improve this article by adding reliable references.For other uses, see Headphones (disambiguation).The telephone earpiece such as the one pictured at the right was common around the turn of the 20th century.From the earpiece developed the headphones.Very sensitive headphones such as those manufactured by Brandes around 1919 were commonly used for early radio work.These early headphones used moving iron drivers, either single ended or balanced armature.They also had very poor comfort compared to modern types, usually having no padding and too often having excessive clamping force to the head.Impedance varied, but 1,000 to 2,000 ohms was common, which suited both triodes and crystal sets.When used with early powered radios, the headphone was normally connected to the positive high voltage battery terminal, and the other battery terminal was securely earthed.The use of bare electrical connections meant some users could be shocked if they touched the bare headphone connections while adjusting an uncomfortable headset.Applications
Headphones can be used both with fixed equipment such as CD or DVD players, home theater, personal computers and with portable devices (e.In radio studios, DJs use a pair of headphones when talking to the microphone while the speakers are turned off, to eliminate acoustic feedback and monitor their own voice.Wired headphones are attached to an audio source.Walkman portable stereo tape player.Headphones that include a microphone are more commonly known as Headsets, and are more often targeted for communication than recreational listening.Telephone headsets are very commonly used in Call Centers and offices, but are sometimes used at home.Gamers might choose to use a headset in order to both hear the game sounds and talk to their fellow gamers.Wired mobile phone headsets are sometimes called as "Mobile Handsfree", and are basically a pair of earphones with a microphone module connected to the cable.Wireless mobile handsfree also comes in different types, and the most common type nowadays is the Bluetooth headset that rides on the ear.Wireless and wired intercom units used by the coaching staff of professional sports and for broadcast control and event management often employ a headset attachment.Circumaural headphones have large pads that surround the outer ear.This type of headphone is commonly used in recording studios and among audio enthusiasts.Earbuds or earphones, such as these that ship with the Apple's iPod, rest in the outer part of the ear canal.Earbuds or earphones are headphones of a smaller size that are placed directly outside of the ear canal, but without fully enveloping it.They are generally inexpensive and are favored for their portability and convenience.IEMs, are earbuds that are inserted directly into the ear canal.Canalphones offer portability similar to earbuds, and also act as earplugs to block out environmental noise.Custom canalphones are fitted to individuals.Because of the individualized labor involved, custom IEMs are more expensive than universal IEMs.Typically, the housing, or earcup of a headphone will be either open or closed.The operating principle consists of a stationary magnetic element affixed to the frame of the headphone which sets up a static magnetic field.The magnetic element in headphones is typically composed of ferrite or neodymium.Electrostatic
Electrostatic drivers consist of a thin, electrically charged diaphragm, typically a coated PET film membrane, suspended between two perforated metal plates (electrodes).The electrical sound signal is applied to the electrodes creating an electrical field; depending on the polarity of this field, the diaphragm is drawn towards one of the plates.Electrostatic headphones are powered by anything from 100v to over 1kV, and are in proximity to a user's head.Electret
An electret driver functions along the same electromechanical means as an electrostatic driver.Balanced armature transducer with armature balanced and exerting no force on diaphragm.Balanced armature transducer with armature torqued and exerting a force on diaphragm.When precisely centered in the magnetic field there is no net force on the armature, hence the term 'balanced.Today they are typically used only in canalphones and hearing aids due to their diminutive size and low impedance.Orthodynamic
Orthodynamic, or magnetostatic drivers, are either composed of a thinly pressed disc made of tightly coiled fine aluminium wire affixed to a mylar sheet or of a printed circuit.The diaphragm is then sandwiched between two magnets which have the same polarity facing each other.AMT hybrid design because of the shape of its diaphragm.Benefits and limitations
Headphones may be used to prevent other people from hearing the sound either for privacy or to prevent disturbance, as in listening in a public library.Part of their ability to do so comes from the lack of any need to perform room correction treatments with headphones.Marketed claims such as 'frequency response 4 Hz to 20 kHz' are usually overstatements; the product's response at frequencies lower than 20 Hz is typically very small.Although modern headphones have been particularly widely sold and used for listening to stereo recordings since the release of the Walkman, there is subjective debate regarding the nature of their reproduction of stereo sound.Stereo recordings represent the position of horizontal depth cues (stereo seperation) via volume differences of the sound in question between the two channels.Through most headphones, because the right and left channels do not combine in this manner, the illusion of the phantom centre can be perceived as lost.Commercial recordings almost always use stereo recording, because historically loudspeaker listening has been more popular than headphone listening.The common scenario in which a replacement might need to be purchased is the physical breakdown of copper wiring at junction points on the cord (at the TRS jack, or at the point of connection to the headphone).This leads to the disappearance of the normal pain associated with higher levels of volumes.Koss introduced the "Safelite" line of cassette players in 1983 with such a warning light.The line was discontinued two years later for lack of interest.However, the user can still choose to listen at dangerously high levels.This page was last modified on 13 June 2008, at 19:11.All text is available under the terms of the GNU Free Documentation License.Sennheiser and

had both connected, we could comfortably listen to music coming through the computer, which is stationed on the floor under the desk.In fact, our listening tests inspired frequent bouts of desk dancing, much to the amusement of neighboring editors.You can even hear a chair squeak in the recording of Jamie Cullum's "Photograph."Everything sounds good, but techno and electronica sound
