Show number 4, 2 of the microphones stopped working. So these were the perfect solution as a little handle that matches the stainless steel. Unfortunately they have changed, and not for the better. Most of the RMAF show involved wandering around seeing if I could find something I liked more than the Aeons, and I just couldn’t. I Got a small, probably would have been more comfy with a medium though as I have a little bit of a belly. I bought a pair of these for myself and liked them so much, I bought 4 more sets for Christmas presents . Sound isolation is also a bit limited, but thats a plus in my book because it does dramatically reduce the likelihood of getting run over while out and about. some other products. The tread has worked flawlessy so far for me through grass, gravel, mud, tree roots and general matted trails. My only concern with it is that there is no cover for it, meaning one side of it is always exposed.
