Headphone & headset
Headphones or headsets have long been used as a means of privately listening to audio programming. Headphones can provide excellent high fidelity audio and are reasonably comfortable. A typical headphone includes two ear pieces joined by a head band, with a speaker in each ear piece. An electrical cable interconnects the two earphones and also connects them to the source, such as an amplifier which drives the speakers. Headphones can be broadly categorized as head band type headphones supported on the head with the audio output component thereof in proximity to the ear, and inner ear type headphones used while inserted in the auricle. Active noise cancellation (ANC) headphones contain microphones that convert environmental noise to an electrical signal that can then be utilized to produce sound of equal amplitude but opposite phase of the ambient noise. The use of a headset allows a user to perform other tasks while having a conversation. Headsets with earphones, and optionally, associated microphones, are well known and widely used in broadcast and two-way communications. Communications headsets typically have a microphone positioned on an adjustable arm that allows a user to move the microphone to a desired position, which the user finds comfortable. Communications headsets can be used in a diversity of applications, and are particularly effective for telephone operators, radio operators, aircraft personnel, and for other situations wherein it is desirable to support "hands free" access to communications systems. Headsets can be classified into three general types in accordance with the type of ear-phone that they employ. In-the-ear type earphones, sometimes referred to as earbuds, fit into the concha, or entrance to a wearer's middle ear. On-the-ear types couple against a lateral face of the auricle, or external ear, of the wearer. Over-the-ear earphones surround and form a closed chamber over the auricle of the listener. Earbud earphones are also in use today with portable entertainment systems. These earphones are placed immediately adjacent the ear canal and provide good audio fidelity, although their placement is sensitive in order to obtain the best performance. Bluetooth is a recently proposed standard for local wireless communication of mobile or potentially mobile devices, such as cellular phones, wireless headsets, computers, printers. Wireless headsets have become increasingly popular in recent years. A wireless headset allows a user to keep both hands free and move about while remaining in communication with a telephone.
