Whatever headphones you decide on, don't just put them in your pocket. I use this case, which is very compact, softer than an Altoids tin, but protective. If you can see, it has a little pouch you can put extra tips in. As I have custom iems, I use it to keep the cleaning tool there. It's been the perfect case for me.
I ordered mine directly from Westone, and the price was around $8, with another $3-ish for shipping, which took about three days. Well worth it.http://www.westone.com/ear/1867/Univ...itor_Case.html
