A Bluetooth speaker is a device with wireless connectivity that is used to untether music devices. It operates within a distance of 50 yards between the music source and the speaker. The device being connected to the speaker should be Bluetooth enabled.
A Bluetooth speaker receives digital audio streams that are typically compressed from the host device. It then decompresses, decodes and amplifies the audio through the built-in speakers. The setup of Bluetooth speakers varies depending on the make and model.
Bluetooth speakers have excellent portability and convenience and are available in all kinds of shapes and sizes. Some use replaceable batteries, some are rechargeable and others are wall-powered units.
