A headset combines a headphone with a microphone. Headsets are made with either a single-earpiece (mono) or a double-earpiece (mono to both ears or stereo). Headsets provide the equivalent functionality of a telephone handset but with hands-free operation. They have many uses including in call centers and other telephone-intensive jobs and for anybody wishing to have both hands free during a telephone conversation.
Types of headset
Headsets are available in single-earpiece and double-earpiece designs. Single-earpiece headsets are known as monaural headsets. Double-earpiece headsets may support stereo sound (two slightly different channels of audio signal, one for each earpiece), or use the same audio channel for both ear-pieces.
Monaural headsets free up one ear, allowing interaction with others and awareness of surroundings. Telephone headsets are monaural, even for double-earpiece designs, because telephone offers only single-channel input and output.
For computer or other audio applications, where the sources offer two-channel output, stereo headsets are the norm; use of a headset instead of headphones allows use for communications (usually monaural) in addition to listening to stereo sources. Telephone headsets generally use 150-ohm loudspeakers with a narrower frequency range than those also used for entertainment. Stereo computer headsets, on the other hand, use 32-ohm speakers with a broader frequency range.
Originally known as Don Knotts Overdrive (DKO), this Hollywood-based performance art/rock ensemble began their career in 1993, consisting of Howard Hallis (today, an artist), Taylor Stacy (Magic Pacer, Erin Martin Band, Deletists, Reverz Engineers, Electromagnetic), Bobby Hecksher (Charles Brown Superstar, Magic Pacer, The Warlocks), Bob Mustachio (Magic Pacer, The Warlocks) and Daniel Meyer (Dashboard Prophets, Farflung).
Originally visually and shock-rock based, dressing as monsters, superheroes, animals, naked, etc., the LA party band released a 7" single in 1994 on Wrong Dimension Records.
In 1995, Hallis and Hecksher left the group as their full-length CD debut was released nationally.
Due to legal challenges from the actual Don Knotts, the group changed their moniker to The Headset.
Most microphones today use electromagnetic induction (dynamic microphones), capacitance change (condenser microphones) or piezoelectricity (piezoelectric microphones) to produce an electrical signal from air pressure variations. Microphones typically need to be connected to a preamplifier before the signal can be amplified with an audio power amplifier and a speaker or recorded.
In June 2009, E1 Entertainment announced the album. The group came together when Joe Budden was working on a song for his Halfway House album and enlisted the services of Crooked I, Joell Ortiz and Royce da 5'9" for a song entitled "Slaughterhouse". Inspired by the vibe of track and the immediate chemistry of the four rappers, a plan was immediately made to form the supergroup.
The album release date was changed from July 7 to August 11. Royce da 5'9" said that the group wanted more time to put into set up and marketing with its label E1 Music. On his interview with AllHipHop on June 12, Royce told: "Even though this [group] is a new way of doing business, we still gotta stick to the old school script when it comes time to market this, to have the proper time to set up a record. We’re not idiots. We understand the concept of labels throwing something against the wall and seeing if it sticks. That’s not what we are in business to do. We’re still in the business of selling records, because we feel we have a great product to present to the public."
