Work great for a solid year, after that, roll of the dice... - OTTO Engineering NoizeBarrier Micro

I bought these in 2019 and it is not 2025. I have replaced them twice under warranty. The first set was DOA when I opened them up. The second set stopped amplifying sound after about 6 months. Now on my third set and one of the buds no longer amplifies.

WHEN they work, they are great and I love them. I use them to hunt, shoot, mow the lawn, operate power tools, etc. They just do not last. I have not had issues with keeping a charge like others have, my issue is they no longer pick up sound and play it.

Customer service has been great while in warranty. This will be the first time I see what they will do for me out of warranty. Very disappointed. I spent almost 1,000 getting custom silicone buds made for my ear canal to use these, as I love them when they work.
