Technically, an MP3 player is categorized as a DAP or digital audio player. DAPs can do three main functions, which are to store music files, organize them and then play them for the user. The name MP3 player is the nickname for DAPs.

If the MP3 player can play videos or view images as well, then that DAP is termed a portable media player. People who want to use their MP3 players can usually listen to the audio through earphones that are connected to the MP3 player via a 3.5 mm jack. To power the MP3 player, the device may rely on rechargeable batteries.

Your DAP can be further defined as either a Flash-based player, a Hard Drive-based player, or as an MP3 CD player. The Flash-based player type of DAP relies on either removable memory cards, or on internal flash memory to store your music files. The Hard Drive-based player type of DAP uses a hard disk drive and may store a higher volume of music files compared to the Flash-based player type. This type of MP3 Player is sometimes called a Digital Jukebox. The last type of DAP which is the MP3 CD player basically works by reading MP3 files that are burned into a CD.

On the other hand, the new type of MP3 player is the one that utilizes wireless headphone technology. MP3 players that rely on wireless headphone technology allow users to enjoy the convenience of wireless technology yet still hear audio whose quality is equal to that of CDs. At the same time, such MP3 players can run on as much as 10 hours of battery life at one time, using this wireless headphone technology.

Why are MP3 players so popular nowadays? One reason is that the advances in MP3 technology mean that current MP3 players have audio quality that is almost as good as that provided by CDs. For this reason, many people feel that MP3 players are a good investment. Another reason people buy MP3 players is that they offer users more portable ways to store and bring with them their music collection. For instance, a person with 10 CDs has to lug around more weight than person who uses MP3 players to store the same number of song titles contained in those 10 CDs. So people who dislike being saddled with so many discs to listen to in a day may choose MP3 players instead as their preferred audio medium or storage facility.

Now what about cheap MP3 players, are they any good? Should you invest in cheap MP3 players instead of the high end ones? Well, if lower cost alone is what you are seeking, then the cheap MP3 players might fit the bill for you. However, like any other electronic gadgets and items, the price you pay may determine how many features you can get from the cheap MP3 players you buy. Generally, the lower cost MP3 players have less reliable functions because quality costs money. And although there are cheap MP3 players that may pass the quality standards, you as a user would have to determine the features and the benefits of buying and using the cheaper MP3 players.

Lastly, paying a little bit more for quality makes more sense than trying to be content with a less costly but less reliable gadget. So if you had to choose between cheap MP3 players and the more reliable MP3 players, take time to evaluate the gadget first and look for reliable testimonials if you are to use a cheaper MP3 player.
