MP3 players are basically divided into 2 main groups: those with a hard disk and those with internal memory (Flash Memory).

MP3 Players with internal memory are lighter, and its storage capacity revolves around 8GB. Some players have the option to extend capacity through an external card.

MP3 players with a hard disk, are characterized by their largest storage capacity (10GB and up). They are slightly heavier and more sensitive because of their delicate internal mechanism.

MP3 or MP4

MP4 Players are those which can be used to view a video on your screen. Some allow you to view a short video while others allow you to view full movies and it depends on the storage capacity of the player. These players are also known as PMP (Portable Media Player).

It is noteworthy that although its name appears in MP4 word, it does not mean that the player supports this format. It is advisable to check before buying. Usually, the players support different formats such as Divx, Xvid, ASF and more.

If you want to watch movies on the player, we recommend a not so small screen for a more comfortable experience.

The MP4 player capacity is very important because a video file is larger than music.

If what you want is just music, it is highly recommended to you that players support the basic formats (MP3, WMA, OGG, AAC etc.).

The sound quality

Several factors influence the quality of sound, and generally it does not depend on the player.

Headphones: one that mostly influences the sound quality. Even the best player will not give us a good sound without good headphones. Usually every player comes with headphones; however these are not always of good quality, so we recommend purchasing a better quality headphone for better sound.

Bitrates: most MP3/MP4 players present this data in unit of kbps. The figure refers to the file compression. The figure is higher, the sound quality is better. Also the file size grows as the growth of the Bitrates. The best bit rate that represents the relationship between quality and volume is the 192KBPS, while files with less than 128KBPS bit rates have very poor sound quality.

Preset modes: in the new players there has the option to predetermine a specific way (Pop, Jazz, Classic, etc.).

The screen

The type and size of the screen depend on the usage of given player. If only for music player, you can choose a simple screen - not so great - single color, but sometimes players with color screens come with interactive menus. It is clear that the larger the screen is, the more energy the player consumes.

If what you are looking for is watching videos, then they need a player with screen not less than 3 inches, and are recommended to pay special attention to the resolution and brightness.

FM Radio

If radio listening is something of your daily routine, then you have 2 options: radio players that have joined the player or those which have integrated into their headphones. This second option is not recommended because without the original hearing you can not hear radio player.

PC Connection

The standard connection for most MP3/MP4 players is USB. This connection allows you to pass information from the PC to the device. Several versions of USB connection: USB 1.0, USB 2.0 and USB 3.0, the most used nowadays is USB 2.0.

Battery

Most MP3/MP4 players come with an integrated battery. The great advantage of this type battery is that it can be recharged again and again. There are players that can be loaded through a PC, while others are connected to electricity.

Another method, and perhaps simplest, is the use of conventional batteries. The great advantage of conventional batteries is that they may run out of batteries because they can be replaced at any time.
