Excerpt: Philips 4GB Mp3 Player (SA4146) The Philips 4GB mp3 player is a great mp3 player with some great features. This Particular Mp3 player even has a built in microphone which means you can record, all on your mp3 player. I paid about £40 for my Philips mp3 player on a bid. It was second hand but in excellent condition. The earphones you get with this Mp3 player are excellent. The sound quality overall is very high.
