Query: Sony NW-E507 Network Walkman 1 GB Digital Music Player with FM Tuner

I am pleased with this product. I was considering purchasing the apple i-pod which does not have an fm tuner. That was the determining factor in my selection. The product works well while the soft ware is a little difficult to use but with time is becoming more routine.Mps sound quality is good. I use this item primarily on commuter trains and the fm reception is fair. It is small enough to fit in you shirt pocket and it looks cool. A single charge can last me all week, approx 8 hrs of use each week.I did not like the headphone extension cable. The male / female ends have to be inserted at the proper depth or no audio is heard. I would recommend offering or purchasing two different headphones with different cable length if a short cable is desired.
