t-break posted a review on the Sennheiser CX890i Headphones

One of the first things you’ll notice about the Sennheiser CX890i is their unique design. Basically a sapphire-like dome casing is created to give it that transparent feel, while the PCB’s green color and black metal components give it a distinctive look and feel.

Following down you have the remote control with built-in mic that acts as your control system for receiving calls and handling audio tracks. The remote is coated in a silver finish, which, I’m afraid will wear out as time passes; otherwise get easily scratched.
