First of all, it is essential to remember that there is a wide range of products – both for smartphones and MP3 players – with different features and performance. Generally speaking, specific players offer better audio quality than cell phones, mainly because their sole purpose is to reproduce sound.
The difference in performance further increases when you look at hi-res models. If you analyze the technical specs for the sound of cell phones, you will notice that little information is given. If you read a hi-fi player’s characteristics, on the other hand, a long list of specs is given. This shows why MP3 players are more efficient than cell phones.
