I have three speaker docks I keep at work (for three separate rooms):
Here is my recommended order:
1. Logitech S715i
2. Logitech Pure-Fi Anywhere 2
3. Klipsch iGroove SXT
All sound great, but I put the Klipsch last because it doesn't have a built-in rechargeable battery, thus limiting portability.
All three sets come with remotes, but the Klipsch remote doesn't work well under fluorescent lighting. The Logitech remotes worked.
The Logitech sets also come with a carrying case to hold the speaker set, remote, and the charging cable.
Ultimately, I chose the Logitech S715 over the Logitech Pure-Fi Anywhere 2 is that the dock portion works well with all iPod/iPhone models that support the dock without having to use those universal dock holders, and most importantly, the sound is simply better.
