It's very delicate but completely safe to travel with I'd say in a Pelican case.
The soft bag would protect the finish but they're extremely delicate when it comes to the headband. I'd recommend again anything but a Pelican case or hard case of some sort.
Question, how is the red finish holding up to wear and tear on the th900's? If purchased, I would take them traveling, take them to the office, I'm fine with taking a larger set of headphones around because of the quality...
But I am concerned the finish is just not going to be durable..
Has someone used them like this, traveled with them? Yes I could place them in a big foam lined box... But would they be fine is a soft bag? Or am I nuts for even pondering this?
