Today's technology gives your customers the option of wired or wireless speakers. There are advantages and disadvantages to each. The popularity of surround-sound audio has at times been hampered by the daunting task of setting up a traditional wired system, which involves unpacking all the wires, making sure they're long enough, and getting them all into the right plugs in each speaker before your customer can even begin to arrange his system. The advent of wireless speakers allows your customers to avoid this hassle.

Mobility is another popular feature of wireless systems. Routing wire to the ideal speaker position may be cost prohibitive or impossible depending upon a home's construction or the limitations of renting an apartment. Because they are not tied down by wires, wireless speakers are not limited in terms of placement. Your customers have the freedom to set up their system precisely how and where they want.

Wireless speakers come in a variety of sizes and shapes and require no expensive or difficult custom wiring. And with a wireless system, your customers do not have to worry about trying to hide a huge mass of wires.

To be clear, most wireless speaker systems are not entirely wire-free. In the audio world, wireless essentially means many fewer wires. But in terms of convenience, simplicity, and flexibility, the difference can be great.

On the downside, wireless speakers can sometimes encounter interference from strong Wi-Fi or radio frequencies in high-traffic wireless zones. To offset this problem, most wireless speakers come with knobs that allow your customers to change which frequency the speakers are picking up. By changing the system's frequency, the interference should vanish.

There is some argument as to whether the quality of sound in wireless speakers is below that of similar wired models. As wireless technology has improved over the years, this has become less of an issue. However there are those who believe the quality of the sound will always be best when using traditional wired speakers. It is always wise for your customers to listen for themselves.
