Conclusion: SA4020 contains all the basic functionalities of an mp3 player. Basically the player is designed for “on the go” listeners, like those who workout. Keeping that in mind, the first feature that everyone would want is an FM tuner and walla!, you got yourself an FM tuner. The FM tuner works fairly well in good reception. The SA 4020 also includes a voice recording feature which to our disappointment gave almost adequate results (files stored in WAV format).
