Wireless headphones are a very convenient tool for business, for exercise, and for pleasure. They give the listener extra freedom without the inconvenience of wires to tangle or trip over. Connecting cables are always a distraction. With headphone connecting cables, the listener is tethered to his computer or listening device and can’t move more than just a few feet at the very most. If a set of headphones has a fixed cable that is not detachable, and if the cable gets caught on something and is damaged, you may have to throw away the whole set.
A set of cordless headphones can make a person much more productive. Without the cable a listener can walk around, cook at the stove, take care of children, tend to other business or do just about anything within the range of his headphones. Most wireless headphones have a range about 30 feet (10 meters) from his listening device, and some have a range of up to 300 feet (100 meters). You can do a lot with that kind of freedom.
There are three popular kinds of cableless headphones. Each different kind has its own set of advantages and disadvantages. RF (radio frequency) headphones and Bluetooth headphones both use radio signals to connect with a listening device. Their signal (within its range limit) can go through walls, floors, and ceilings. However, other electrical devices and appliances nearby can cause static interference.
IR (infrared red) headphones use a beam of infrared light, like that in a TV remote, to transmit the signal to the headphones. These have the clearest sound with no radio static interference at all, but since infrared light can’t travel through walls, the listener must stay in the same room where the listening source is.
Many sets of wireless headphones and earphones are designed for special functions. Some are designed especially for use with telephones. Others are special for computer gaming. And many are general purpose headphones. Listed below are some of the most popular.
