I'd also like to find something better.  I am using 3M worktunes muffs, but
if I wear sunglasses there is a gap around the ear seals that reduce the
effectiveity quite a lot.  I tried EAR brand rubber plugs, and various
brands of foam plugs, but they won't stay in my ears.

John, good point about the sun glasses.  I wear them as well so they need
to be included in the equation for whatever the solution might be.

I like the foam ear plugs best.  I roll them tight so they slip right in 
the ear and I've never had one fall out.  I find when almost fully 
inserted, they work pretty good.  If I'm using something extra loud like 
a router, I add ear muffs.

On the mower, do you have the option of changing the direction of the 
muffler or adding a tip to the muffler?  If not, can you add a shroud of 
some sort between your head and the muffler?  Just like we have lots of 
options for car mufflers, is there an optional muffler that reduces the 
sound more?

When using foam ear plugs, roll them between your fingers so they get
small.  Then reach over your head with the opposite hand and pull up
on the top of your ear while you insert the rolled plug in your ear.
Looks goofy, gets results.

When it comes to ear plugs, I have had much better luck with silicone ones than foam.  Like these: https://www.cvs.com/shop/cvs-health-ultra-soft-silicone-earplugs-antimicrobial-protection-prodid-457795. On occasion, I have used them under ‘ear muff’ protectors and the combination works especially well.  Technically, heavy duty foam ones have a higher db reduction rating, but I have found the silicone ones seal better and thus do a better job of reducing noise.

Thanks all, for the replies.

Late last week I ordered a pair of 3M Peltor Optime 105 ear muffs from
Amazon.  Yesterday I mowed with them and they are definitely better than
the Echo branded ear muffs that I had been using.

When I use ear plugs I prefer the silicone style over the foam style.  I'd
prefer not to wear ear plugs AND ear muffs.

The muffler on the mower points out to the side.  Changing the direction of
the muffler is definitely something to consider although at most about all
I can do is put a 90 on the end of the nipple sticking out of the muffler
and angling it to the rear.  Now that I have new ear muffs redirection
would be the next thing to try.

While I'd love to have a pair of Bose Quiet Comfort 20 or something
similar, the price is pretty daunting and knowing how rough I am with
things I don't know that they would last the number of years I would expect
for the price.   One thing I really like about ear muff style protection is
they keep my ears from getting sunburned!

If the 3M ear muffs and redirection don't cut it for the long haul then
I'll look into ANR ear muffs.

Thanks again for the suggestions.

Brad

ANR - Active Noise Reduction - indeed does protect hearing.  The units vary 
in sophistication, but all essentially have a microphone in each earcup 
that "listens" to the sound inside.  The circuitry of course knows what 
it's putting out (assuming this is an actual audio headset and not just a 
hearing protector) and ignores that.  It generates an opposite-phase sound 
wave to whatever it "hears" as noise, and thus the noise and the ANR signal 
cancel each other.  Your ear received less sound pressure.

I have a pair of Peltor muffs for shooting with microphones in front so 
that you can speak with someone and still be ready when a shot goes off. 
They're good, but for mowing the lawn I still turn off the sound from the 
microphones and they're more quiet.

I also have aftermarket ANR kits I installed in several of my aviation 
headsets and they're far more effective even for mowing.  But the price 
difference is huge.  The Peltor ANR muffs were about $50, while the ANR 
kits I put in my David Clark headsets cost over $100, on top of a few 
hundred dollars for the headsets themselves.

David Clark sells headsets with ANR from the factory, but they're over 
$500, and Bose aviation headsets are about $1,000.  Ear plugs are cheaper 
if they're satisfactory.
