The outer shell is made out of hard plastic of a cheaper acrylic variety than what you might expect to find on a $649 pair of IEM’s. They aren’t fragile per-se, but just don’t feel like they cost as much as they do. They won’t break if you accidentally swing them at a friend, but you’d expect something a bit heftier, perhaps. The good news is that they’re extremely light and the material doesn’t effect, negatively at least, the sound coming out of them. They seem cheaply put together, light and like they’re going to fall apart almost. But there were never any actual structural issues during testing. These are just the universal models and build-quality is far higher on the custom made, molded version you can get. You can customize them to your hearts content, with different materials and colors and such.
The cord that comes with them is detachable and an industry standard 2-pin affair. So if you wanted, you could find different cords of differing quality, width, material, to replace it should you be so inclined. Or if you accidentally break this cable. Which is rather thin and feels as if it’ll rip with a slight amount of force. It’s unfortunate that the stock cable on something that costs this much is so dainty. Though during the last 6 weeks there haven’t been actual issues with a bit of rough use while working out and occasionally getting tangled and pulled out of my ear by my clumsiness.

As the specs show us, these are tuned more towards providing healthy amounts of bass, something that’s lacking at times in these in-ear-monitors. These in particular are meant for those recording artists that want to emphasize those lower frequencies so they can better hear the nuances of their instruments. They have other, differently tuned IEM’s as well, for those that want more presence in the mid-range, or even high-end.
