It's been over a decade since the first MP3 players and iPods hit the market. For some people, they've replaced all other audio and video players (radios, CDs, photo albums) for day-to-day use. Naturally, off-the-shelf electronics work fine off-the-shelf, but people don't want off-the-shelf; they want to personalize their toys. They also want them to do things they weren't designed to do. MP3 and iPod accessories provide those additional functions and turn your ordinary digital audio player into a made-to-order personal audio system all your friends will envy.
This MP3 player and iPod accessory buying guide will list a few of the ever-increasing number of cool add-ons available and help you decide how to buy MP3 and iPod accessories that work for you.
First, and foremost, get electronics accessories that fit! iPods and MP3 players come in many, many sizes. Most are just about, but not exactly, the same size, so the case for second generation music players may not fit first or third generation music players. Read the description carefully and you'll be fine.
Second, get the audio accessories that meet your needs. If you have a small room and want to use you iPod as the audio system, get an iPod dock. If you have a large room, a dock won't get it done; you'll need a real home theater that includes an iPod dock.
Adapters & chargers

All iPods and MP3 players have a plug to attach a charger. The other end plugs into the power source -- a computer, car cigarette lighter or wall electrical outlet. Some music players are experimenting with solar cell chargers. Some chargers have both USB and FireWire plugs. In place of a charger, you can attach an external battery and add hours to your listening pleasure.
The standard iPod or MP3 player has a 3.5mm jack and a USB plug. This works for many consumer electronics applications, but not all, so you might need some adapters. Adapters allow you to connect your digital audio player to home theater speakers; adapters can split signals to two devices; they can even help your little music player run a full surround sound stereo system. If you have a car cassette tape player, you can buy an adapter that runs your iPod or MP3 player through your tape player into the car audio system.
Cases
Cases should be the first accessories you purchase, because they protect your music player from damage as well as personalize it. Digital audio cases are available in several materials:

All audio equipment cases come with a variety of options: Some iPods and MP3 player covers feature clear plastic over the screen or click wheel; others have openings. Some f cases include a belt clip or lanyard (neck strap or wrist strap), while some are armbands. Some cases allow you to dock or recharge your digital audio player without removing the case. Finally, consider the weight, thickness and size of the case before you buy. Weigh all the options and features and you'll be very happy with what you choose.

FM transmitters
Many new car audio and home theater systems can connect to your digital audio player via MP3 or iPod transmitter. FM transmitters are far neater, more flexible and more convenient than cables. The iPod transmitter connects to the music player and transmits to the radio in your home theater or car audio system. The earmarks of a good FM transmitter include working on multiple frequencies (stations), small size and a long transmission range.
Headphones
The easy part: If it has a 3.5mm (1/8-inch) jack, it will fit iPods and MP3 players. The hard part: Choose the best headphones for you; that means trial and error and maybe buying several headphones for different circumstances. Something to consider when thinking about buying headphones: cordless headphones can be very nice, in fact, an absolute must if you have to move around the room a lot.

Docks

Most iPods and MP3 players connect via USB cable to your computer or your home audio system. For those who want a little more convenience and fewer wires, the iPod dock was created. As with digital cameras, audio equipment docking stations (also called docks or cradles) connect directly--no computer required. Primarily, docks are MP3 player speakers or iPod speakers, but other features are available. They can recharge batteries even while you use them. Some include remote controls, clocks, radios, CD players, video players and cables to connect to other video and audio equipment.

Speaker systems
Digital audio speaker systems have something more than simply docking your iPod or MP3 player. They can be simple desktop or even handheld MP3 speakers, or they can be a room-filling surround sound iPod speaker system. Like docks, iPod and MP3 speakers come in a wide variety of shapes and sizes, and may include clocks, radios, CD players or video players, so you're sure to find one to fit your room and your budget.
Be careful how you roll up audio cables. All wires have a natural twist, and wrapping wires the wrong way can kink or break thin wires.
If you don't get them wet, if you wipe them off when they get dusty, if you keep them away from strong magnets, your iPod and MP3 accessories will probably last until they are technological dinosaurs.
