An amplifier and loudspeaker with Bluetooth wireless connectivity that is paired (pre-associated) with one or more smartphones, tablets, iPods, or computers. It then decompresses, decodes, and amplifies the audio through the built-in speakers.
A portable speaker allows you to listen to audiobooks or music while cooking even showering without a messy cable. Unlike using headphones, you can still hear a pot boiling over, or a doorbell buzzing.
Wireless Portable Speaker are composed of two units: the main speaker unit combining the loudspeaker itself with an RF receiver, and an RF transmitter unit. The transmitter connects to the audio output of any audio devices such as hi-fi equipment, televisions, computers, MP3 players, etc.
