I have tried several in-ear brands, electronic and custom molded. I have a weird left ear canal and all of them are either so hard to put in(the custom molded ones) or just don't fit tight enough to be of any great benefit for me. After trying the latest, greatest I ended up staying with on-ear models.
I did buy a jar of the "foamies". They actually work really well and reduce the sound as much or more than anything else. They do reduce being able to hear conversations though so they may not be the best if you were taking class. I think they would be fine for competition though.
