While working this weekend - I realized that the hearing protection is really important while mowing. Regular landscaping and chores, not so much. So, that makes the 3M Worktunes with BT and no FM radio a clear winner. They really are nice and at a good price point.
For active hearing protection, I asked some owners of MSA Sordin headsets. They are military grade and are priced from about $120 to $500+ . I was told that they work well for tractor and chainsaw work. They seem to be very well made, and comfortable. But, these things have a way of getting lost or shredded. I will try the 3M's
