If your headset uses a single, combined jack for audio output and microphone input, you can use the splitter adapter to connect your headset to notebooks and PCs that have separate audio and microphone connectors.
Many headsets1 today, including the Sound Blaster EVO and Sound Blaster Tactic3D Fury, have a single, combined 3.5mm 4-pole jack for both audio output and microphone input that are meant for use with smartphones and newer notebooks and PCs.
However, connecting these headsets to notebooks or PCs that have separate audio and microphone connectors means that you can only hear the audio on your headset, while its microphone would effectively be unusable. Here's where the Sound Blaster Audio/Mic Splitter Adapter comes in. It effectively splits the headset's audio output and microphone input into two separate jacks so that microphone usage is restored.
