Havent stood for a long period if time yet, but they seem pretty perfect for what Im looking for. I am using it in my garage. These fit great and are pretty comfortable. I have not installed it yet because we are still debating where to put it. I can even skip under eye concealer and not be self conscious! This isn?t as powerful as another one we have. The lids are aluminum and not treated so if you get them wet they will corrode. They are better then my air pods. I only needed a hammer and a screwdriver (used a power one but manual would have been doable I?m sure). Edit: I just wanted to add onto this review about 4 months later.
