I got a sly profit, went for the titanium look one, and think its a good mask. I dont have any problems with hearing with it, but a friend of mine cut the padding a little around the ear section to make it better for him to hear. Pros to it are that it gives good visibility, but also gives very good protection, especially compared to the I4's. Just covers more of the face it seems. My one con with it is that I find it fogs up a little quickly, but then I try to have a second visor to swap out to.
Hope that helps
