The new X-Series Walkman has some very nice touches. Incorporating a wide 3-inch OLED touch screen, the display delivers a picture with extremely high contrast, exceptional color reproduction and a rapid response time. The device is also incredibly easy to use, as the X-series utilizes both touch panel operation and a hybrid button system to improve navigation and functionality.
But the good times don’t stop at the tactile expeience. The X-Series Walkman uses a unique digital noise canceling (DNC) software engine to block out ambient noise, while providing a high-quality audio experience.
Finally, the X-Series is wi-fi enabled, has a quick charge feature and can play up to 12 hours of music on a full charge.
