The U100 is a Wi-Fi-capable MP4 player. Since it can stream music from the Internet, it is free from internal storage restrictions. A distinct feature of the player is its matte neon-coloured lower segment, which sets a contrast to the smooth screen and features a slot for microSD cards. The player has a 3.1” touchscreen, up to 16 GB internal memory and an FM tuner. Videos can be replayed with a quality of 720p.
