Details About Earphones
Earphones are basically a pair of tiny loudspeaker drivers attached to or on the head itself, usually behind a user’s ears. They are electrical transducers, which transform an electric signal into a corresponding sound vibration. It is important to notice that an earphone does not incorporate any wires, and so it is also called a wireless earphone. In addition, earphones may be worn in one ear alone, but there are also models that can be used together with a full-sized earphone to create a more comprehensive sound experience.
Wireless earphones, however, have several advantages that set them apart from their wired counterparts. The obvious advantage is that there is no wire connecting the earphones to the listener, thus eliminating noises associated with traditional cables. In addition, some earphones come with noise cancelling headphones which eliminate all other external noise except the ones created by the earphones themselves. These noise cancelling headphones work by reducing sounds around the earphones to ensure that only the driver in the earphone is hearing good quality sound. This is why earphones with noise cancelling headphones often have very good frequency ranges, allowing even those with very sensitive hearing organs to enjoy music.
Another advantage of earphones is that they generally include a frequency response, or more commonly, a band frequency response. The earphone specifications explain what the frequency response looks like. For example, on some earphones, a low-frequency response will be indicated where as on others, it will be shown as a signature. This is useful for matching earphones to the right environment. Many earphones also include an adjustable treble or bass level. This allows you to adjust the strength of the treble to your preference while the bass may be left at its factory default level to prevent irritating background sounds.
