These two products have it all, quality, good construction, lots of features and one of the smallest MP3 players and FM transmitters on the market. I personally love these products and use them everyday whether I use the small MP3 player during a workout, or by using the transmitter in in car on the way home to listen to MP3's without constantly burning them onto a disc. If you have never tried a MP3 player, go get one. You won't know how you enjoyed a workout as much without it.
