Got mine on Saturday and tried them out around the house. I'm very impressed by them compared to others I've seen and tried - especially the battery compartment - once I figured out to turn them right side up to get the first battery to fall into place. I had a different pair - don't remember the brand - demoed to me in a gun store once and the clerk destroyed the ear cuff trying to install the batteries. That brand had you remove the cover over the speaker to install the batteries - not a very robust design but the MSA's inspire confidence it will be long lasting.
