R19U is equipped with Edifier's latest 2.75” full-range speaker unit, engineered to deliver wide and detailed sound with just two speakers. Skillfully designed, a subtle 10 Degree tilt not only greatly reduces interference caused by sound reflecting from the desktop but also projects the sound directly at you. The result is more clear, lifelike sound for everyday audio needs. Manage volume and power on/off with the integrated front control. Less fuss, more fun. With R19U's black wooden enclosure and elegant grey base, Edifier has created a transformative listening experience as well as a stylish addition to any desktop .Setting up R19U is easy. It connects to your laptop or desktop computer with a single USB cable for both power and sound. Fewer cables mean less clutter for your workspace, and it frees up your audio port. Not only can you connect a computer to these high-quality speakers, but the complimentary 3.5 mm AUX cable allows versatility in connecting smartphones, tablets, and game systems for a detailed sound performance.
