Customizable Sound Modes

The Yulong DA9 features three different customizable sound modes. Mode 1 is balanced, while mode 2 is at once delicate and firm, making it a possible preference when listening to classical music. Meanwhile, mode 3 is laid-back with a stronger vocal presence, great for jazz and other vocal-heavy tracks. Working with these filter modes, users can get a new level of enjoyment from their favorite songs.
