Yamaha's legendary studio monitors have been the industry standard for their signature sound, accuracy and classic silhouette for over two decades. The RH10MS Professional Monitor Headphones will carry on that tradition. The RH10MS features S-logic 3 Dimensional Surround Sound. S-Logic takes advantage of the natural acoustics of the listener's ear by sending sound around the listener's head and off the surface of the ear canal. This delivers a more spacious sound without relying on tricks like artificial echo or digital processing, ensuring the monitor's accuracy. Experience every detail of music with S-Logic 3-Dimensional Surround Sound.
