Cheap but good - Radians 430-EHP Electronic Earmuff With Black Padded Headband Black Earcups 430/EHP

These work good but I suspect the comfort and quality are not up to par with much more expensive options. They do seem to work really well, but I only wore them during 1 day of shooting. The electronic feature of turning off sound works well. It seems to shut off during all loud noise events to lessen the shock of the sound in the ear.
