There are many different types of Bluetooth® gadgets that allow wireless connectivity between devices for convenience and ease of use. Though cell phones and cell phone headsets are some of the most common, many other products now allow this type of synchronous, wire-free use as well. Both laptop and desktop computers now frequently include Bluetooth® technology, as well as MP3 devices, USB storage drives, wireless headphones, and others. Each Bluetooth® gadget to be paired must feature Bluetooth® technology specifically. Sometimes this technology can be switched on and off on the device, while other times it is constantly on.
Wireless communication and listening devices are some of the most common Bluetooth® gadgets. Cell phone headsets, for example, often allow people to answer and hang up the phone without ever touching it. Though these are frequently used in the workplace, they are also very common while driving, or even for just walking down the street. In many states it is illegal to talk on a cell phone without using a hands-free device such as one of these Bluetooth® gadgets, making them even more ubiquitous. It should also be noted that other states forbid using such devices while driving.
In addition to headsets for cell phones, headsets for computers, audio systems in cars, or MP3 players are also very common. These allow individuals to wirelessly connect to the stereo systems and listen to music or other audio that way, which can be very convenient. Some televisions even feature this capability now, which can be especially beneficial for households in which one individual stays up to watch TV while everyone else goes to bed. This individual can simply listen to the TV audio through the headset, without disturbing anyone else. Other Bluetooth® gadgets connect directly to a computer, for easier wireless use.
These can include keyboards and mice, most commonly, but they can also include larger items such as printers. Wireless storage devices, such as a USB dongle, also frequently use Bluetooth® to connect to a computer, as well as other Bluetooth® gadgets such as cell phones and MP3 players. This allows users to transfer files quickly and easily without needing to set up a wired connection. As this wireless technology becomes more and more prevalent, it is likely that more devices will be manufactured with Bluetooth® technology in the future. Keep in mind that different Bluetooth® gadgets might have different connectivity ranges, and some older devices may not be compatible with some newer ones.
