Thx for comparison Meoow! :)
I did tested A/B/Cing them too here for the whole night (W1000X, W3000ANV, W5000), see what other people think about their comparison is always a very good story for me :D
Anywy, I ever tried for once using W1000X as portable headphone when I'm on plane, it was only for a short distance though. If you curious, yes, many people that sit around me starred at me when I use it haha.
