Funny you say that. Probably the huge difference between Asia and Europe. I got Ciems especially for these occasions: getting rid of the outside noise when you're outside. I think you get used to it after 5min.
I know, streets in Asia are 100% more intense when it comes to traffic and movement, so i have to try next time i'll be there (somewhere)
i don't touch them inside, using only my home HIFI station.
