Thank you for the suggestion. However, I actually already own the Koss 'plugs'. I have one of the first generations and the foam plugs won't stay in my ears. I heard the newer plugs come with better foam. I actually think they don't sound too bad, but it's really dependent on the fit. If they aren't in the ears quite right, they will sound terrible. I recently found on a few websites that there are some mods that you can do to make the 'plug' sound better. One was to tame the bass so it's not so boomy by closing the ports with a small piece of tape. Surprisingly, it really helps! Another mod was to use regular foam earplugs in place the current plugs. Maybe I'll try this option as well.
