Both these speaker docks make good cases for themselves. If you were to base a decision purely on sound quality then the Logitech Pure-Fi Anywhere set wins the day, with its more musical tone and more pronounced bass. However, the iRhythms A491 is still a decent sounding little travel iPod speaker set and though it doesn't have the style, build or bass of the Logitech Pure-Fi Anywhere set, it does have video out and is also half the price.
