I have some of the older Worktunes and like them. I used them today while running a
carpet cleaner. Probably didn't have to as it's not that loud but it helped turn a not
fun task into somthing tolerable. Certainly didn't hurt anything.
I also like the concept, knowing I can listen to some tunes encourages me to wear the muffs when doing loud things.
Sometime I'm going to get the newer version... Should probably
pick up an mp3 player too.
I'm slipping further and further
behind the times...
