HeadphonesHeadphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earphones or, colloquially, cans. Circumaural ('around the ear') and supra-aural ('over the ear') headphones use a band over the top of the head to hold the speakers in place.
Mixing consoleA mixing console or mixing desk is an electronic device for mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds. Mixers may control analog or digital signals. The modified signals are summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded.
Sound cardA sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.

WalkmanWalkman, stylised as WALKMAN, is a brand of portable audio players manufactured and marketed by Japanese company Sony since 1979. The original Walkman started out as a portable cassette player and the brand was later extended to serve most of Sony's portable audio devices; since 2011 it consists exclusively of digital flash memory players. The current flagship product as of 2022 is the WM1ZM2 player. Walkman cassette players were very popular during the 1980s, which led to "walkman" becoming an unofficial term for personal stereos of any producer or brand.
