Summary: I really like these IEMs. The casing is almost indestructible, they have detachable cables, and the sound is great and very clear for dynamic drivers.
The casing is made from Zirconium. They're advertised as being related to diamond, which isn't true and a little too much marketing speak, they are indeed very very hard.
The sound is a little bit V-shaped with too much emphasis on the bass & treble.
Cons: Little too much bass & treble, expensive now
Summary: These headphones are very unique, both in construction and sound. They are built of Cubic Zirconium, making them extremely durable, and have detachable cables. A jogger literally ran over mine, on concrete, and they aren't even scratched. The finish changes color from a gunmetal grayish color, to a bluegreenish hue in bright light.
Pros: Sound for price, build quality and durability, detachable cables, sound is very detailed and accurate while being very "fun"
Cons: Sound may be too bombastic or extreme for some. Minor issue with nozzle filters falling off(which can be a plus)
