Audio compression technology allows large digital music files to be reduced up to 10 times in size without radically degrading their audio quality. MP3 or WMA are two of the compression formats that let you enjoy a world of digital music on your GoGear player. Download MP3 or WMA songs from authorised music sites on the Internet or create your own MP3 or WMA music files by ripping your audio CDs and transferring them onto your player.

Philips is known for making products which are compatible with many discs available in the market. This audio system lets you enjoy music from CD, CD-R and CD-RW. A single CD can store up to 10 hours of music. CD-RW (CD-Rewritable Compatible) means that your audio system can play both CD-Recordable (CD-R) and CD-Rewritable (CD-RW) discs. CD-R discs are recordable once and can be played on any audio CD player while CD-RW discs can be recorded and rewritten multiple times and can only be played back on compatible audio CD players.
