Let us know what you think of the Otto's, and how they do managing wind noise.
You did not direct the comment at me, but I just picked up a pair of the otto noizebarrier micro and am four hunts in with them. I was previously using the walker silencer 2.0. I decided to upgrade primarily due to wind noise. Otherwise I did not have a problem with the walker silencers. I did not get an exact wind reading, but I hunted with them in what was easily 20+mph winds. I ended up paying $470 for the otto noizebarriers, and my verdict is that I am glad I purchased them. Given the amount of money we spend on other things within the sport, my recommendation is to pony up the money to buy them and cut corners elsewhere. Skip over the $100-$250 price range for electronic plugs and jump straight to these (or perhaps a more expensive brand). I will keep the walkers as a backup set in the case of uncharged batteries, etc but do not expect them to get a lot of use.
Otto Noizebarrier pros:
Handle wind noise better than any other electronics I have used. When I was hunting and I could hear wind noise, if I took them out I generally could still hear the wind in my ears without the earpro in. The wind noise also sounds more or less like natural wind noise instead of the static over a PA system you get from many electronic hearing protections. This is their largest advantage.
There is a little but not much in the way of crunching brush, etc. Huge improvement over the other electronic hearing protection I have used.
They seem to return to normal hearing after gunfire faster than other electronic hearing protection I have used.
They are comfortable for my ear canal. I would them for 8 hours straight and did not feel the need to take them out. This has not been the case with the Walkers. After about 3 hours with the walkers, I feel like I need to take them out to let my ear canal relax. The correct replacement foam tips might help with this for the Walkers.
I maintain directionality of the flush in all except for the most extreme cases. e.g. pushing through the really thick stuff. Honestly, I am not sure I would have been able to tell direction of flush without the hearing protection given the amount of noise I make busting through phragmites.
Comes with spare filters for keeping ear wax out of the electronic components.
My list of cons are not dealbreakers, and I am overall happy with the Ottos, but nevertheless there is always room for improvement.
Otto Noizebarrier cons:
No bluetooth capability.
Limited number of sound level to select from for amplification.
The case is "tactical" and slightly cheesy. It is also slightly bulkier than needed. That said, it seems durable and will serve the purpose.
When you turn off one earplug, the other does not automatically turn off.
The plugs charge from the case on a stored battery in the case. However, the case needs to be open in order to charge the case. This is inconvenient for charging in the truck and always having them in your hunting rig.
If I yell or use a quail call, it attenuates but does not completely cut out my own sound.
