Wireless speakers are composed of two units: a 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. An RCA plug is normally used to achieve this. The receiver is positioned where the listener wants the sound to be, providing the freedom to move the wireless speakers around without the need of using cables.

Batteries may last for 3 to as long as 24 hours; almost all wireless speakers operate on rechargeable batteries that are not replaceable, so that the lifespan of these speakers is that of their batteries. The signal frequency range used by wireless speakers is generally the same as that used by cordless telephones — 900 MHz. The RF signal can traverse walls and floors/ceilings. Most manufacturers claim the signal transmits over a range of 150 to 300 feet (50 to 100 m).
