Speakers
Speakers are devices that output audio by converting digital sounds in analogue sounds so that people can hear the sound properly. Most speakers are wired as its cheaper to have wired speakers and they produce better sound because the data is directly being transmitted through a cable and not wirelesslly/ by using Bluetooth. But there are still a lot of Bluetooth and wireless speakers on the market that provide excellent sound, without the use of wire, which makes them more portable and better for certain occasions.
​
Wattage is to do with how many watts the speaker outputs per channel, if the wattage is higher then the volume can be higher up to the maximum but this could lead to overheating.
​
Dedicated controls are buttons on the speakers that lets users manually control certain features, such as the bass, trebble and the volume. But some speakers don't have all of these features and can just have, volume up/down, pause/play, and skip buttons.
