Types of iPod speakers

Making the connection

Speakers can connect to an iPod in a couple of different ways. One is through the iPod's proprietary docking connector (on full-size iPod and iPod nano models). Those speakers include a built-in dock that usually, but not always, works similarly to Apple's iPod dock and will charge your iPod's batteries (when the speakers are connected to an AC source). This type of speaker usually allows you to use a remote to control your iPod and other functions. Some even have video passthrough, which will send a video signal from a fifth-generation video iPod to a monitor or another display device.

However, not all iPods (including the iPod shuffle) have a docking connector, and not all docking connectors are identical. Apple has addressed this issue somewhat by creating a universal dock that will mate with all present and future dockable iPods through the use of adapters. Unfortunately, not all speakers use that dock, and those that don't will only be compatible with some iPods.

Clearly, then, a key step in selecting a speaker system is to make sure that the model you
are considering is compatible with your iPod. Most -- but not all -- reviews we saw include compatibility information, but nowhere is it easier to see than at the Playlist magazine website (http://playlistmag.com/products/speakers.php), where the main review landing page includes a list of compatible iPod models for every iPod speaker system covered.

Even if a speaker system you like is not compatible with your iPod, you can probably still use it. Almost all iPod speakers can connect to any iPod (or other MP3 player) via their 3.5 mm (minijack) headphone jack. While connecting that way is not nearly as elegant as using a docking connector, and increases clutter since you'll need to use a cable, it certainly opens up your options. Most powered speakers intended for use with other MP3 players, laptops, desktop PCs and more can also be connected via an iPod's 3.5 mm headphone jack.

The latest iPod models, the third-generation iPod nano and the iPod Classic, use the same docking connector as their predecessors, so should work fine with iPod speakers.

Types of iPod speakers

While the wide array of iPod speakers can overwhelm a first-time buyer, it's fairly easy to separate what's available into four or so broad segments. While there is certainly some crossover between types, concentrating on the type of speaker system that best fits your needs and budget will help save you time.

Budget speakers: If all you want is to untether yourself from your earbuds and generate enough sound to fill a small room or office, budget speakers (under $100) are a good alternative. Although you should not expect top-notch sound quality, reviews say that some do a surprisingly good job without denting your wallet too badly. While iPod-specific speakers are available in this category, some good choices can be found among speakers intended for a wider audience (those which connect to an iPod or other MP3 player through the headphone jack).

Portable speakers: Portable speakers are designed for the traveling iPod user. Some are truly tiny -- small enough to fit in a briefcase or large pocketbook. Larger models will fit better in a suitcase or backpack. Remember that designing a speaker for size -- as is the case with portable iPod speakers -- usually involves some sacrifices, typically in sound quality. That said, a few portable speakers can hold their own with their stay-at-home brethren, according to reviews. Some portable speakers can run off a battery.

One-piece bookshelf speakers: While most iPod speaker systems are one-piece designs, incorporating all of the speaker elements and the iPod dock in one cabinet, these larger iPod one-piece speakers are clearly intended to stay in one place. Sound quality is generally good, and sometimes very good. In addition, many feature innovative and attractive styling, making a statement beyond the sound they produce.

High-end iPod speakers: These speakers are designed for those looking for the best possible sound, regardless of cost. While some audiophiles remain aghast that any iPod speaker be considered high-end (because audiophiles consider compressed digital formats to be inferior), a few speaker systems have earned some begrudging respect. This category includes one-piece speakers as well as multi-enclosure component speakers that let you place the left and right channel speakers farther apart to achieve a better stereo effect.
