Tritton 720+ Headset Questions

Can i use a USB splitter on the Headset to let two different devices hear the sound coming through the Mixamp?

Does anyone know the answer to this? i wanted to know because when i play video games people in my house sometimes watch but with my headset on they would be staring at a tv with no sound, i want to be able to split it to a small speaker or something so that they have some sound while i get the 7.1 dolby so i can play well
