I own a set of V-Moda Vibes and I thoroughly enjoy them. I bought them after returning the UE SuperFi 3. I returned the UEs because they didn't fit right, bass was virtually non-existent (which could have been due to the poor fit) and they blocked out too much sound. I couldn't hear my phone at my desk at work.
I find the V-Moda Vibes to be the exact opposite of the UE SuperFi 3. The choice of headphones is driven by their intended application. Some people like lots of sound isolation while others want less.
