If you are going with wired HyperX headsets, you will primarily find single 3.5 mm and dual 3.5 mm connectors. The primary difference between these is that a single 3.5 mm connector will have 4 poles. This means that it carries both the headphone and the microphone signal making it great for gaming consoles, smartphones, and laptops with just a single audio port. On the other hand, dual 3.5 mm connectors are ideal for desktops with separate audio input and output ports.
