The sony walkman is alot more costly than many other portable CD players, but is reliable and has additional abilities. I have had no problems with it what so ever and the sound quality is good. If you are hoping to listen to old CDs, which would otherwise be thrown away, as well as downloading new songs from computers on to it, then this is ideal. However, I think that it is better value to buy an ipod or mp3 player as well as a cheap CD player for the same price, as you can carry it around easily and run with it if necessary and you can listen to old CDs when you are on a train for example, which will not get stolen! The Soney D-NE300 does the job when listening to music and looks attractive, however there are machines half the price which will do the same.
Music lovers can now enjoy more of their favorite tunes on a single disc with eight new ATRAC CD Walkman players, all with the ability to playback ATRAC3plus and MP3 encoded CD-R/RW discs. The ATRAC3plus format is a high-quality audio compression technology developed by Sony that effectively reduces the size of audio files while preserving more of the sound quality. With ATRAC3plus compression, more audio files can be burned to a disc using a PC's CD-ROM drive. Music can be burned and compressed to 256, 132, 105, 66, 64 or 48 kbps (kilobits per second), allowing consumers to store more music or record at higher fidelity. By compressing at 48 kbps, users can enjoy up to 490 songs on one disc.
The D-NE300 model is a great way for just about anyone to take his or her music off the PC and with them anywhere. Offered in an ice-cool shade of blue, this introductory player looks great while achieving more than 80 hours of continuous ATRAC playback on two "AA" batteries.
