(Electronics) Has long battery life when<a href="http://xweziyqbm.com"> hldniog</a> a charge as most Sony MP3 players do! Also great when syncing videos as well as music. Better volume range than previous MP3 players! Also, 16 GB storage is more than enough for my 1000+ songs, playlists, and 30+ videos! Also, is very easy to use and the radio gets superior reception in places where other brands of radios will fade in and out! This is my second of the same make and model MP3 player. One, I take with me when I go out, and the other teams up with a pair of good external speakers to provide great sound in my home, which means no need of a big shelf stereo system!
