DownBeats are 100% effective
I am typically not an ear plugs guy, but lately I've been feeling the harsh effect of loud-ass bass music from some of the shows I've gone to.  Started wearing DownBeats and now I bring them to almost any show I go to.  Super comfortable, filters the bad sound and you can barely tell you're got them in.  I'd recommend these to anyone looking for a good and affordable set of of plugs...especially if you are as obsessed with electronic music as me.
