Headphones, headsets & earphones
Headphones, headsets and earphones are used in many areas associated with audio visual equipment and systems: they are quite similar in their function and the words may be used interchangeably at many times, but there are some key differences between them.
Headset: A headset is essential a pair of headphones that includes a microphone. The term headset tends to imply that the microphone may be mounted on a short boom to the side which can be positioned as needed, but the microphone could equally well be an inline microphone.
Headsets are ideal for applications like receptionists or for call centres where the wearer needs to hear the caller and the caller needs to hear a clear voice without high levels of noise from the surroundings. Headsets are also very useful for many Skype or similar communications to cut the external noise and reduce echo, although modern phones are able to handle this very well.
Headphones: Headphones themselves are essentially a pair of small speakers that are attached to a band that is positioned across the wearer’s head to enable the speakers to be positioned over the ears. Normally there are cushions that are placed around the speakers and over the ears for comfort and sound insulation.
Headphones provide a very personal and what may be termed immersive listening experience. Unlike true loudspeakers, headphone transducers do not need to move large volumes of air and therefore they can deliver a very impressive sound. However the experience is different to that of speakers as the sound is heard in the plane of the headphones and does not come from in front of behind.
Headphones are often used with higher end audio visual applications. Often they are used for serious music listening, in studios, for audio and video editing and many other applications. They are also used for music on the go, and can often be used with a wireless connection, i.e. wireless headphones / Bluetooth headphones, where the lack of a connecting lead makes them easier to use.
Earphones: The term earphone has now come to describe the form of transducer that has dispensed with the cushioning and consists of a small earpiece that fits into the ear itself. This makes the transducer / ear connection even more direct and the earphones or ear pieces need to move even less air.
Earphones can be made to be very small - they can easily be carried in a small pocket when not in use and they are much less bulky to wear than traditional headphones. This makes them ideal for those travelling about on public transport, etc, for runners and the like. They can easily be powered by mobile phones or other music players and as such they are ideal for music on the go.
There is a very wide variety of earphones available for purchase from the very low cost items, to those that are expensive, but produce very high quality audio.
Headphone and earphone capabilities
There are also other capabilities that can be introduced into headphones and earphones to make them more convenient to use.
Noise cancelling headphones & earphones: Noise cancelling headphones have the very attractive feature that they are able to remove much of the external noise by electronic means. They sample the noise outside the headphone and then use this to apply an equal and opposite signal into the headphones, thereby cancelling the noise.
Noise cancelling headphones provide significant levels of noise reduction and as such they are ideal for use when commuting, air travel or anywhere that there may be high levels of noise. Noise cancelling versions of both headphones and earphones are available.
Noise cancelling headphones and wireless headphones / Bluetooth headphones tend not to be used for studio work as they may introduce some levels of distortion to the signal. Bluetooth uses some compression of the audio signal and therefore may not be considered suitable for the very high end audio visual applications.
Also noise cancelling headphones will try to cancel out unwanted noise and as a result may introduce some unwanted elements tot he audio. That said, both Bluetooth headphones and noice cancelling headphones can provide very high quality audio and are ideal for most situations.Essentially a current is passed though a movable coil which is held ina static magnetic field. As current is passed though the coil, forces are set up causing vibrations which are then passed to a diaphragm which is physically connected to the coil.
Planar magnetic headphones & earphones: This type of headphone / earphone driver technology uses a thin diaphragm with an embedded conductor suspended between magnets either side. As the diaphragm can be amde very thin, they respond very accurately to the sound signal passing through the conductor.
Balanced armature: This type of headphone or earphone driver was initially developed for use with hearing aids. As the headphone drivers are small, they are ideal for hearing aids, although they are also used for in-ear monitors, etc.
Piezoelectric earpiece: This type of earpiece is often called a crystal earpiece because it uses a piezoelectric crystal to convert the electrical variations into sound.
Although these are some of the major types of earphone and headphone technology, there are a number of other approaches and designs that have been used and are still being used for some products.
