Bluetooth speaker

An amplifier and loudspeaker with Bluetooth wireless connectivity that is paired (pre-associated) with one or more smartphones, tablets, iPods or computers. Available in all sizes, including replaceable battery and rechargeable models, as well as wall-powered units, the Bluetooth speaker receives digital audio streams from the host device, which are typically compressed. It then decompresses, decodes and amplifies the audio through the built-in speakers. See Bluetooth audio and Bluetooth pairing.

A Premium Bluetooth Speaker
