I started with Dashlane and still think it's pretty good... the interface is great, they always seen to be working on improving their stuff (like with the recent automatic password change), and their software is pretty much everywhere.

The primary piece of advice needed to be said here though is this: you cannot break the laws of physics, no matter what Dr. Bose or the kid at Best Buy will tell you. No amount of sub-woofer trickery, magic computer modeling, and "innovative materials" will get little tiny cubes to sound like real music or movies…
