Ear Plugs - Spark Plugs

I prefer comfortable ear plugs to muffs- especially practicing & in warm/hot weather.
I like "SPARK PLUGS".  --- Soft- comfortable - tapered so you can insert different depths for comfort.   - -  I put them in all the way then withdraw to comfort depth.
Moldex Spark Plugs - I get the box of 200pr: #6604.

mark them L & R, use 2-maybe 3 times - discard    2¢-YMMV
