With the addition of directional sound you get a much deeper audio experience. We have teamed up with Dolby&reg;, so that you can go from stereo to full 7.1 channel Dolby&reg; surround sound at the slide of a button. It&rsquo;s the difference between hearing the game and being in the center of the action.</span></p>
