I can use exactly your mentality and say, oh B&W are so out dated, with existing technology they couldn't come out something much lighter, they need to put heavy metal can on your head that make you walk like a bull on the street bcoz B&W felt you are more safe with more heavy metal. Lol..
And with existing technology, they couldn't figure out how to make an proper ANC headphones. Ya we talk about it science too. Lol...
BTW, don't get me wrong. I absolutely like B&W SQ too. I have a P7W for 10 days, after that I refuse to walk like a bull so it ended at someone else head
