I was going to get the K550 for its closed cups, leather(?) pads, and generally flat response to get around all these, but I scored some ASG-1.2's at a price I couldn't resist. And given how these can pass off as hearing aids so long as my phone or other player isn't seen attached to it when I get off the metro train, criminals would likely not be as easily tempted by these.(4)
(4) [. . .] Expats typically don't have to worry about these because they usually get a flat near work and won't have to go through certain places on the way to the suburbs or the residential buroughs, so when they wonder about these things, chances are they just don't do the same commute as most other people.
Whoa! It's easy for anyone to be free-thinking when it doesn't affect them. Like you, I'm careful not wear any expensive-looking headphones where I work in town here in Chicago. Enjoy the ASG-1.
