I mean I have the Pilot Pad and did try it on the NO, let's just say that it stretches the entire headband upwards when you wear it, making the pads sit on your head more vertically so for some people it might seal better yes, which then results in them being able to hear the sound of NO properly by having a good seal.
For me, I have a smaller head and I don't have seal issues with the Owls so I'm not using the Pilot Pad, it doesn't look too bad on it though
But it definitely improves comfort even further, if you ever had a slight hot-spot on your head with Owls/Hawks, the Pilot Pad will definitely solve that issue.
TLDR It is not a bad investment comfort-wise but don't expect mind-blowing sound quality increase from it.
Btw I'm using the Hybrid pads from NightHawks on it and they really make the Owls shine
