Wireless speakers are a new innovation of the good old speakers we use for our auditory enjoyment. So if you hate wires, then you can get rid of some of them through this new innovation. There can be two types of wireless speakers. The first one is the radio type which uses radio frequencies to transfer sound. The other one is the infrared type which, as its name suggests, utilizes infrared technology.
The radio type can pass its frequency through walls as it uses the same concept as our regular radio does. However, the signal can be easily interfered by different frequencies especially if there are other appliances activated around (i.e. TV, radio, microwave, etc.). The infrared type, on the other hand, does not care about the number of appliances working simultaneously. However, its range is limited to the sight of the infrared. Thus, if there is a blockade between the speakers, then the sound will be weaker.
Wireless speakers are easy to set-up. It is very free of movement between the speakers (you can take it outdoors as long as it is inside the range of the signal). Typically, you are free of the worries of having your friends and/or family tripping down because of wires.
However, some wireless speakers are not totally wireless. Some still need wire to connect to power supply. If you don’t like this idea, then there are battery-operated wireless speakers. However, the batteries get drained easily and needs replacement every now and then. The frequencies can also be interfered regardless of the speaker using radio or infrared technology. The cost is also higher compared to the usual wired speakers. And lastly, despite the freedom of movement you get with these speakers, the freedom is very limited to the range of the frequencies (especially infrared ones).
