Yes, I just had a post the same as yours only a few days ago.. Not sure where it is now but some people have heard it and most don't think it will affect anything.. Mine also make the sound but I also have some Stingers and they are a little more quiet.
G%'s typical response is the "old ones" did and the new ones don't, if you hear a whistle sound then it's the fletchings... Whatever... That's why it only does it with that broadhead and no others..

Great broadheads minus the slightly louder flight noise...
