Why Gamers Use 2 Headphones

The answer is very simple: IN EAR headphones, that is, those with a thin cable that are under the large headphones (OVER EAR) are those that reproduce the sound of games and computer communication. While the external headphones reproduce white noise throughout the event.

Why play white noise while players are in full competition?

All of this is done to ensure that no external sounds (crowd, sound effects, commentators) can reach the players and they use the information to their advantage and also to avoid distractions.
The IN EAR headphones that the professional gamers use like tyler1, ninja or mr beast use at the event are of consumer quality, this means that some use the same headphones from day to day to play as well as others prefer exclusive models such as the Razer Hammerhead Pro

However, we cannot say the same for the OVER EAR headphones that rest on the players’ heads. These are often (high-end) aviation headphones, which are specifically designed to reduce outside noise. In addition to fulfilling the function of blocking sounds, they reproduce white noise to further prevent the chances of players hearing the crowd.
