I have two pair of the WorkTunes headsets and have owned them for several years. I find that they do a great job of attenuating the machine noise in the shop, and I like to listen to the radio at a low level when I'm working. Doing so with these on lets me hear the music while the machines are operating and it's great that they are protecting my hearing at the same time. They're also great for use while mowing the lawn. Mine are the older versions, so they don't have the ability to plug an MP3 or other external music source into them. The new digital version is supposed to have this capability, so maybe I'll be upgrading soon. About the best price that I've seen on them seems to be at Lowes (wish they carried them when I bought mine).
