For decades, speakers have carried an ominous association with wires, much like phones were in days gone by. Stereo owners were always well acquainted with wires. The speakers could only go as far as the wires went and where the wires went, they could be seen. As with other wired devices, hiding speaker wires usually meant drilling holes in the wall or floor. This made moving the speakers difficult because you'd have to move the wires too.
The advent of home theater introduced even more wires into the home environment. Rather than just two speakers (as with a stereo), home theaters call for six or more speakers, all with wires! This not only made setting up a home theater difficult, but it made the room look messy with all those wires. Traditional methods were used to hide the wires and we all got used to them, until they came out with wireless speakers, of course. Now you can place speakers where you want them. If you want to rearrange them, you can right because as long as you can find a place to plug them into power, you're good.
Convenience
This leads us to one of the obvious advantages of wireless speakers: convenience. No longer must holes be drilled in the floor and wires run every time you want to set up something new. If you want to change rooms, it's a piece of cake. Wireless speakers are convenient.
Visual appeal
The other reason that leads people to wireless speakers is visual appeal. No longer do you have to love with unsightly wires that destroy the aesthetics of you house. You can place your speakers anywhere you want them without having to worry what to do with the wires.
Operation
We all agree that wireless has done much to improve speakers, but how do they work? Basically, at the home theater receiver, rather than connecting speakers, you hook up a transmitter to the speaker outputs. The transmitter then broadcasts the sound to the speakers over radio frequencies. Now you have home theater sound without the drawbacks of wires.
Other applications
Wired speakers almost anywhere can be replaced with their wireless counterparts. For computers, you can get speakers that connect with Bluetooth technology. Other speaker sets connect with standard 5.8 GHz, 2.4 GHz or 900 MHz, or even over a wireless network. Whether for paging, public address, or just an old fashioned stereo, wireless technology can make speakers easy to use and look better too.
