Clear Voice Our Clear Voice technology has been improved to make human voices even more audible. Use the Clear Voice feature to hear every word – from YouTube videos to movies and shows, especially when background music and sound effects try to take center stage. FOUR SOUND MODES Four different sound modes are accessible, making it easy to match the sound to the content being played and the desired mood. Standard mode is ideal for TV shows, while Stereo mode is best for music and concert videos. Try Game mode to immerse yourself in your latest battle, and use Movie mode to create an expansive theatre experience.
