Yes, you can get cheaper ear plugs, but these allow you to hear far more clearly while still reducing the volume. They can be a little tricky to insert, I find I need to grab the top of my ear while inserting these, and it helps if they are moistened before insertion (condensation from a cold beverage is enough). They took a bit of getting used to as they are a little more snug in my ears than some other kinds, but totally worth it for the clarity.
