Bluetooth is basically a wireless connection between 2 devices. Some common ones for computers are headsets, headphones and speakers. Bluetooth can also sometimes sync your smartphone to your car. I’m a casual gamer and have a nice pair of Bluetooth headphones that sound real good and were under 40 dollars. You can find them on Amazon. To me I can’t justify the major difference in price for such little quality difference. I’m more focused on the game.
