I use Howard Leight too. I absolutely love them for both comfort and protection.
I went through all of the custom molds, different shapes of latex, rubber, and foam, then one day stumbled on the Leights at work—generally the airline supplies 3m yellow foam, either barrel or taper—but I happened to be in the garage bays, and the mechanics were all using the Leights. Long story short, I tried ’em, I loved ‘em.
I use them on the motorcycle, playing music, going to concerts, and I still use them at work.
