Portable Audio for your iPod

Additional Images

With Polk's miDock Portfolio, you can listen to your iPod anytime, anywhere. The miDock's compact and light size enables you to carry it around in your briefcase or bag, wherever you're going. Bring it to work, to school or on vacation. Don't have access to an outlet? Don't worry, the miDock can operate on 4 AA batteries (not included) for over 8 hours! Of course, you can also plug it in with the supplied AC adaptor for unlimited listening.

The miDock Portfolio is compatible with all iPod models, and has an auxiliary input for other MP3 players or computer. We supply adaptors to accommodate all the iPod generations, including the Mini and Nano. The Shuffle and iPhone can connect through the auxiliary input. The docking station will even charge your iPod while it is plugged in. (special note- will not charge, but will play 4th Gen Nano and 2nd Gen Touch)

Don't let the miDock Portfolio's unobtrusive looks fool you. The high-efficiency digital amplification technology makes the speakers sound much bigger than they actually are. The digital amplification technology is paired with four metal cone micro drivers. This means that each channel, left and right, has two speakers dedicated to high quality performance. If you compare the miDock Portfolio with similar units (even those that are priced much higher), you'll be shocked by how much better the miDock Portfolio sounds.

We know there are a million iPod docks out there. Why should you choose Polk's? The miDock Portfolio is the easiest to travel with (it folds flat), it comes with a protective case, and it's the best-sounding, ultra-compact portable iPod dock you can buy.

  • ultra compact portable audio player

What are the differences between the Polk miDocks?

The miDock Portfolio, miDock10, and miDock Studio all provide high-quality sound for iPod playback, but each has a slightly different feature set.

miDock Studio miDock10 miDock Portfolio
Allows easy access to the iPod keypad, but as a result does not have the protective docking enclosure. The miDock Studio focuses on great sound, providing the best bass and high-quality listening experience of the miDocks. Whatever your needs are, you're bound to find the perfect iPod sound system in our miDock Family. Larger than the Portfolio and can play louder with more bass. The carrying handles on the side and the enclosed docking compartment to protect your iPod make it easy to carry around. The smallest and most portable of the miDock Family. You can fold the Portfolio up, stick it in its convenient carrying case and slide it into your briefcase or purse for ultimate portability.
