- | Generally speaking, latency is the difference in time between cause and effect. In human-computer interaction (HCI), latency is the time that passes before a user perceives the reactions to his actions. The perception is not limited to one channel but can be auditory, visual or haptic in nature [1]. High latency leads to poor performance and user experience in the HCI[2, 3]. Video games are also affected by these negative effects. Players score fewer points, need more time to work on certain tasks, or can not solve certain tasks at all [4, 5]. | + | Generally speaking, latency is the difference in time between cause and effect.

+ | The sounds of a game are important to how users feel while playing and how well they perform in-game. Therefore, developers have placed a steadily increasing focus on audio and sounds in games[6]. | ||

+ | Since the proliferation of wireless headphones there has been a discussion on the differences between wired and wireless [7]. Most wireless headphones use Bluetooth, a short-range communication method. In order to send the sound to the headphones, Bluetooth compresses the data before sending it and then unpacks it afterwards to play the sounds [8, 9]. | ||
+ | This process of compressing and unpacking takes some time, which is one of the reasons wireless methods have a greater latency. | ||
+ | |||
+ | This work wants to find out, if and how this latency impacts user experience and performance. | ||
