More comfortable
•     Performance ear seals are tapered to provide a more natural  fit, for greater comfort and stability
•     Plush ear seals provide 20% more surface area than competitors, for a better seal around glasses frames and a more comfortable distribution of side pressure
•     Larger cup cavity provides 50% more space for your ears, allowing the entire ear to  to fit comfortably inside, while preventing the pain caused by seals pressing against the edge of the ear
•     Low-profile stainless steel headband follows the curve of the head for more comfortable distribution of weight and side pressure
More durable
•     New rugged cables built around a Kevlar core deliver more strength and  flexibility with less  weight than standard cables
•     Nearly 100% of the headset is made from stainless steel and magnesium
•     Magnesium ear cups are both strong and light, while delivering superior high-frequency noise attenuation
More clarity
