By using short-range wireless communication technology, Bluetooth technology essentially works to connect two devices together. The need for cables or wires is eliminated by this. Through wireless headphones, Bluetooth allows you to listen to music from your mobile phone, tablet or iPad.

How does Bluetooth work?

Short-range radio is used by Bluetooth technology to link two devices together. Connecting various portable electronic devices such as headphones eliminates the use of cables. A uniform structure is specified by the standards of Bluetooth for communication between a wide range of devices with minimal user effort.

Using an RF topology known as a “star topology”, Bluetooth devices are managed.  You can have one master and up to seven active slaves, under this topology. For providing the synchronization to all the slaves, the master is responsible. This is known as a piconet. As either a master or a slave, any given device can be part of one or more piconets. This is what makes Bluetooth technology so powerful.

When was Bluetooth invented?

Bluetooth was invented back in 1994, but the first Bluetooth phone didn’t hit shelves until 2001.

The Bluetooth standard was originally conceived by Dr Jaap Haartsen at Ericsson back in 1994. It was named for a renowned Viking and king who united Denmark and Norway in the 10th century. At the time, it was designed to replace RS-232 telecommunication cables, a much older standard conceived in 1960, by using short-range UHF radio waves between 2.4 and 2.485 GHz. Although this occupies very similar frequencies to Wi-Fi, Bluetooth has always been designed as a much shorter range and lower power alternative.

How to connect Bluetooth headphones to Xbox one

To your Xbox One, you can connect Bluetooth headphones. But it won’t be as simple as connecting headphones to your phone unless you own one of a handful of specific headsets.

Bluetooth is not there in the Xbox One. Instead, Xbox Wireless is Microsoft’s own proprietary system which is created.

Even a 3.5mm audio jack was not there in the first round of Xbox One controllers. You need the Xbox One Stereo Headset Adapter, whether you’re connecting wireless or wired headphones(a chunky first-party peripheral that plugs into your Xbox pad).

By providing the missing 3.5mm female audio port, this bit of kit was originally intended to connect wired headphones to the console.
