Bluetooth speakers are a type of wireless speakers that are aimed at improving convenience and comfort of listening to music or watching videos. Unlike the traditional speakers which are connected to the sound system or audio source via cables, this type has no wires. What this means is that you can use the speakers on devices such as stereo systems, iPods, tablets, smartphones, and more without having to fix a cable to a specified port of jack. You can also move with speaker around without carrying the audio source.
There is usually some confusion between bluetooth and Wi-Fi speakers. Truth is that both are wireless types of speakers and are not connected to source of sound via a cable. However, they operate quite differently. Bluetooth speakers follow similar technology and protocol that is found in car speaker systems and cellphones. The sound is wirelessly transmitted from the source via airwaves and is received by the bluetooth earpiece. Unlike Wi-Fi speakers which require a bridge between the audio source and speaker, bluetooth speakers connect directly to the source.
