It has a blue LED flashing randomly or when pressing a button.ĭevices sold in Europe and the USA (YP-U3 J Janus) are MTP and have a tags library. The "now playing" screen and the DNSe effects are the same as on the U2 but the main menu is much different. Contrary to its predecessor, the U3 has touch controls (which was often criticized in reviews ), a new blue OLED screen and a half-size sliding USB connector. It comes in 3 capacities (1, 2 and 4 GB) and 5 colors (Black, White, Blue, Green, Pink). The YP-U3 was first spotted end of March 2007, then officially announced in May 2007 by Samsung Japan and released in June/July in Asia and Europe. There is no major change in the firmware except the presence of the new DNSe sound engine, first introduced a few months ago on the YP-T7F. Also, it now has a negative screen (white font and black background). The main differences concern the hardware: the USB port is no longer retractable and is covered by a transparent cap, allowing glowing effects with two blue LEDs.

Overall the U2 is quite similar to its predecessor. In Europe two MSC versions were available: one without FM tuner and another one (YP-U2 R) with a RDS FM tuner. In the USA the U2 was sold as a MTP device (YP-U2 J Janus) with an FM tuner too. The YP-U2 was released in different versions depending on the geographical area: in Korea the U2 was MSC only, featuring an FM tuner.

It comes in 3 capacities (512MB, 1GB, 2GB) and 2 colors (black and white). The Samsung YP-U2 was first introduced at the CES in January 2006 then released in April 2006 in the US. The U1 is the only player from the U series along with the latest U7 to be UMS only in any geographical area. However, it is possible to install the Korean firmware on a European or American model. The player also supports SRS WOW HD sound enhancement but only with the latest Korean firmware v3.150 latest EU and US firmware v3.152 does not include it. It features 3 EQ presets and a 9-band user EQ. It supports MP3, WMA, WAV, ASF and OGG files. It uses a non-removable rechargeable battery with a stated runtime of 13 hours.

It features a voice recorder but no FM tuner. The design was thus completely new but the firmware and the UI are very similar to previous models such as YP-MT6 and YP-C1. It was Samsung's first mp3 player with an integrated USB key. A 2GB version was later released early 2006. It first came in 3 capacities (256MB, 512MB and 1GB) and 2 colors (black and white). The YP-U1 was first announced in August 2005 then released in October 2005 in Asia and Europe and early November 2005 in the US.
