Pros: Probably the best single armature IEM
Cons: They're are more stylish options
Nobody's likely to steal these based on their looks alone, which are kind of stylish in a teutonic minimalist sort of way, but it's disappointing when people wearing neon pink plastic get more compliments that you. The plus, of course, is the amazing sound quality. If you don't mind getting hit by the bus you didn't hear, these are the best choice for amped or unamped portable sound; even an iPod can drive them acceptably, and better players like the Sony X can drive them fantastically.
