The LTB MG51-USB True 5.1 Surround Headphone Set delivers 5.1 Dolby surround in a headset setup. The LTB MG51-USB uses a unique three chamber per earpiece design that allows for full surround sound without the need for a large setup, or even a larger room. With a built in USB 5.1 sound card, the MG51 needs no other connections excepting a single USB. Aside from TV and movies, the LTB MG51-USB is up for the challenge of 5.1 games, and even includes a built in microphone for two way communication.
