As the time develops, MP3 is still popular, and the mini MP3 already has become the fashion trends. Meanwhile we find 
the MP3 in dealextreme.com is not only cute, but also very cheap. Hence, the following question is how to choose a suitable MP3 which is fit yourself and its price is reasonable.
No. 1 Internal Memory is More Important Than Function.
Recently, large internal memory almost becomes the trend and main stream. For some people, such as clerks in company and students, large internal memory can store songs, and still can use for storing files or recording some learns or lectures at the same time, moreover sometimes you may still need store some pictures.
No. 2 “Deceptive” Phenomenon of Play Time.
Play time for measuring a MP3 is a very important index, so when you choose a MP3, you need pay attention on its play time. Why does a MP3 can have “deceptive” phenomenon? The mainly reason is for a MP3′s play time has very big relation with environment, and battery power. In the cold winter, play time will shorten, contrarily in the hot summer, it will be longer, which is why we can see some one holding MP3 in hands on the streets of winter, it is for promoting battery’s temperature to lengthen play time. And you need know play time which is tested by manufactures is to turn down volume to be lowest and don’t do any operations in the 28 degree of thermostatic room, so tested time likes this is certainly unbelievable.
No. 3 Seek Tonal Quality.
Signal-to-noise ratio is the strong-weak contrast of useful elements and noise of signal, and we often use decibels to express, the higher it is, the less its produced noise expresses. Above 85 decibels’ MP3 player is our first choice. But if we buy it online, how can we check its tonal quality? Without a doubt, tonal quality of the famous brand MP3 is absolutely good, but they are always very expensive. Nevertheless, we still have another choice, select a reliable or professional online store, such as dealextreme.com, you also can buy a good one with reasonable price here.
