I think you will love these with stock pads.
I also think it is an expensive way to go for portable sound excellence.
I also think the limited edition will make it harder soon to get a good deal.
I also think you will like the cheaper esw9 as well, as I have herd some say it had a similar tone to the hd650, but to me the hd650 was more heavier in sound so these esw11 probably best bet.
I also have to say that leakage is low, BUT
Isolation for listener is not that good.
Yet the sound is subtle deep and just engaging.
Sweet creamy detailed sound hard to put down
