The CX 680 unit consists of a durable plastic and grippy rubber casing with multiple modular components. Soft rubber canal tips, like the EarFins described above, are also included with sizes from small to large. One challenge of sport-oriented headphones is dirt and grime. Sennheiser-Adidas has implemented replaceable foam filters in the ear canal portion of each earpiece to combat this, and generously included an extra set of filters in the accessories. Another sport-oriented feature is water and sweat resistance. The CX 680′s neon yellow-green cable is very flexible, thin and lightweight. While it may seem semi-fragile at first, Sennheiser-Adidas ensures us it'll stand the test of time with its DuPont kevlar reinforcement.
