The LiveSpeakR is highly rated for the large amount of sound produced by a very compact set of speakers. It includes an internal, rechargeable battery – obviating the need for buying batteries, and helping offset the system’s price.

Your iPod Touch or iPhone connects to the LiveSpeakR by plugging in a regular headphone audio cable to your iPod’s audio jack, and connecting the charging cable to the bottom or your iPod.

The LiveSpeakR has a couple special features which will appeal to iPhone owners. It is shielded from cell-phone signals, meaning you do not have to put your phone in airplane mode in order to avoid interference. Second, the system also is helpful for use as a speaker phone, allowing you to amplify the iPhone’s sound and make hands-free calls.

If you’re looking for a unique, very portable iPod Touch or iPhone speaker, the LiveSpeakR may be the right choice – check it out at Amazon.

The Pure-Fi, although small, is an iPod speaker system with excellent sound. There are 4 speakers arrayed across the front of the unit, encompassing 2 two inch tweeters and 2 three inch mid/low range speakers. Logitech advertises the speakers as utilizing “Stereo XL” technology – which is a digital method for making the soundstage seem larger. It can’t compete with speakers on opposite corners of the room, but does an excellent job of helping a tiny speaker system sound large.

As a system made especially for the iPod line, it’s not surprising the Logitech Anywhere 2 includes a built-in dock for your iPod Touch. This is a full fledged dock, allowing you to charge and control your iPod through the portable speaker system (you can even control your iPod with the Pure-Fi’s remote control). Of course, you can always hook up a different audio device through the 3.5 mm input jack.

Making the Pure-Fi 2 a really compelling product is the way it combined all its features with a focus on portability. The system is compact, and includes an attractive, protective travel case. For music on the go, Logitech included a built-in lithium ion battery, providing up to 10 hours of battery powered sound. Although the Pure-Fi runs a somewhat steep ~$115, you have to keep in mind the amount of money you might be saving on batteries.

For the best prices, we recommend purchasing Logitech’s Pure-Fi Anywhere 2 at Amazon or eBay.
