XP400 Headset Technical SpecificationsChat Boost
Chat Boost is a dynamic talkback expander built into the XP400 headset that automatically increases chat volume during loud
moments in your game, so you can always hear your teammates or other players, regardless of the game volume.
Typically, if you turn up a headsets game volume, the incoming chat level from other players could become difficult to hear
over the game sound. However, with Chat Boost, as the game audio increases, the chat volume also increases. When the game
volume quiets down again, Chat Boost automatically returns the chat level to your original volume setting.
To properly set the Chat Boost function:
1. Turn down the volume control on the headset so there’s no game audio.
2. Adjust the chat volume control on the headset so you can hear the chat voices at a comfortable level.
3. Turn up the headset game volume and the chat volume will increase whenever the game gets louder, just as if the chat
volume control is being automatically turned up along with the game level.
WITHOUT Chat Boost,
chat volume is overwhelmed by loud game audio
WITH Chat Boost,
chat volume increases along with game volume
NOTE: If the chat volume on the headset is set too loud, Chat Boost might increase the volume so much that the voices
will distort. If that happens, turn down the chat volume on the headset.

Variable Mic Monitor

The XP400 headset includes a unique variable microphone
monitor feature that allows you to adjust the level of your voice
heard in the headset so you won’t have to shout. This can be
adjusted by turning the MIC MONITOR wheel on the left ear cup.
NOTE: Turning up the mic monitor may cause the mic to pick up room
sounds which will make the silence detector not automatically shut off
the headset when it’s not being used. If the power is not automatically
shutting down, turn down this mic monitor control.
