Sennhessier's
I used the HMEC 45's whilst my order for the 46's arrived, found the anti-noise was better on the older 45's than the current 46's! Now on my second pair of since my last set was stolen. Some goon is probably trying them on his Hi-Fi! It seems I can hear the anti-noise signal whilst sat on the B744 flight deck, lots of wind roar over that big nose! Solid build quality though.
