I use to own a pair of worktunes, but misplaced it. So, went back to the site that I bought them at and noticed now that they have a much more expensive model, but, besides am and fm radio, have a monitering device so you can still hear people talking over machines, radio at same time. Also, can be hooked up to walkie talkie and used as communicator. Peltor makes them, on the pricey side, but I love them better than the worktunes.
Oh, the work tune muffs have a 29 rating. The price on the newer model, paid just under $ 200 bucks, but can you put a price on being able to hear your children still at age 60??
