Which is better, mp3 or mobile phone?

Listening to music with mobile phone and MP3 has its own advantages. Mobile phone lies in powerful search engine, and MP3 lies in the reducibility of sound quality.

The sound quality of ordinary MP3 may not be as good as that of mobile phones. Advanced MP3 has sound certification, and headphones are also very important. A good earphone is necessary.

Playing music on a mobile phone is just a multifunctional performance. If it's really awesome, it's still MP3.

Advantages of listening to music on mobile phone: it can be downloaded online and is easy to carry (at least bring a portable product). Disadvantages: Short battery standby time affects other functions of the mobile phone.

MP3 is more suitable for listening to songs. Disadvantages: With an extra device, songs can't be updated at any time.
