All audio from a game's soundtrack is echoing once.
You may have your headset connected to two different outputs at the same time.
This can happen when you are hooking the headset up using an HDMI cable with one of our stereo headsets. Our stereo headsets have "piggyback"-style RCA audio splitter cables, which have a plug on one side and a jack on the other. Because of this, it's possible to plug your PS3 or XBOX A/V cable into one side of the splitter cable, then plug the cable into your TV.
If you're using an HDMI cable to hook your headset up, there's no need to connect these RCA cables to your TV. The HDMI cable handles both the video and audio. Many newer TVs and HDTVs will have a very slight audio/video delay in them. It will be too quick to notice when playing games, but if you have your headset connected to both the game console's A/V cable and an output on the TV at the same time, this can cause a slight echoing effect.
Simply unplug these RCA audio cables from either your game console or your TV. The headset only needs to be connected to one output at a time.
