New wireless Bluetooth headphones are part of a technology evolution that allow people to listen to audio transmitted from another device with ease. All types of headphones are used to transmit audio from the handset, computer, iPod or any other device that only one person can hear, but a wireless Bluetooth headset is considered the best type. The device is connected to the headphones using Bluetooth connectivity; wireless Bluetooth headphones are intended to be used by wearing a wireless headset device that can transmit sound into either or both ears without wires getting in the way of the user. Thomas Edison invented the first audio amplification device, which has led to the invention of one of the most useful pieces of technology available today: wireless Bluetooth headphones. Wireless Bluetooth headphones can be used in the home, at the office, or traveling and are often used in conjunction with a variety of other devices ranging from MP3 players, to laptops and cell phones. The transmission from a device such as cell phone, or laptop which the set of wireless Bluetooth headphones is connected to, converts radio signals and electrical signals and one way or another produces sound. Using only tiny transistors, wireless Bluetooth headphones are capable of providing a large volume of sound; they can operate as louspeakers, or can be quietened for personal/private use. In the year 2000, Bluetooth Special Interest Group, after two years of numerous experiments to get a high quality output, were able to implement Adoptive Frequency-hopping Spread Spectrum (AFH). The wireless Bluetooth headphones were introduced to the public originally by IBM, Intel, Nokia, Toshiba and Ericsson. Since then, wireless Bluetooth headphones have become a significant accessory that a lot of people want or must have. They are incredibly useful for drivers, as they don't require the cell phone to be held when in operation. Since traffic rules and state laws prohibit the use of mobile phones while driving a vehicle, this offers a better alternative, as calls can be forwarded through the headset so the phone doesn't need to be touched! Even for those who don't drive, a Bluetooth headset is a great accessory, as the user no longer has to worry about breaking wires or catching their headphones on things they are passing. The process of using a wireless Bluetooth headset includes transmitting audio from a Bluetooth-enabled cell phone or audio system by pairing both gadgets. As long as both the wireless Bluetooth headphones and the devices are compatible, they will connect automatically within a range of up to 30 feet. It is even possible to connect up to several devices at the same time, if needed.
