King of the Sink
I bought a pair of these today, mainly to just listen to some music as I commute to work. Don't worry, I don't have it up loud. What impressed me most, though, was that these are the best general ear plugs I've used so far. They cut down much more wind and other noise than anything else I've tried, still let you hear the important stuff like sirens, and are much more comfortable than standard ear plugs. If any of you are thinking of something similar, I can definitely recommend them. They are a little pricey, but worth it IMHO.
