And then bluetooth appeared, with which speeds skyrocketed. It’s Bluetooth connection method through which it provides connection and exchange of information between different types of devices, such as mobile phones, laptops, printers and bluetooth headsets. It works on the principle of radio technology or radio waves and is intended for low power consumption, which is the reason why it is most often found in smaller devices, such as mobile phones or bluetooth headsets.
There is one interesting thing about the name Bluetooth. Bluetooth was named after the Danish king Harald the Blue-toothed, who ruled at the end of the 10th century. Harald was known as a skilled diplomat and often managed to establish communication and understanding between multiple parties, even those at loggerheads and warring parties. The inventors of bluetooth technology, in memory of him, used his nickname as a name for their technology, through which they enabled different devices to communicate with each other. In any case, the color blue represented royal power at that time, and the king himself did not dream that his nickname would be eternal.

Today, the most popular application of this technology are headphones and amplifiers. Bluetooth headset are the most common and favorite accessory of today!

Connecting headphones and devices to music or mobile phone is very simple and easy automatically. When the headset is switched on, it is set on the mobile phone so that the bluetooth is turned on. The device automatically recognizes the bluetooth headset and pairing is complete. The connection is established and you can immediately indulge in your favorite music, and talk at the same time, if someone calls you. This connection is sustainable in the range of 10 meters. That’s why you can put your phone in a pocket or bag without disconnecting.
