The yp-k3jqg is one of the best purches ive made for a mp3 in over a year. The sound is incredible its like you are there in the studio with the artist. I also love the graphics that are displayed while listing to music. everytime the sound effect changes so does the display.it is also wonderful becasue of the auto power off after a few mintues of being on pause.Its very good on keeping a great battery. For people who workout alot or on the go all the time its very convient. What i also like about the yp is that you are able to put your own personal pictures on the screen. The touch controls are also two thumbs up. and when youve had enough of the music you have downloaded there is a f.m. radio that has very good quality.I have already recommend this to mother and she just loves it. I love samsung if all my products could be made be made by samsung then i would never have a worry.
