Additional Details ------------------------------ Product description: The Ultimate Gray Ghost is the no-holds-barred category killer headphone. This is one headphone you have to try for yourself in order to believe. Starts out with the famous Original Gray Ghost headphone and adds in all the custom enhancements you want. Now you too can have the ultimate sound quality made possible by special speaker elements in a tuned cavity design. This design means greater sensitivity to tiny targets and more raw power at full volume. The Original Gray Ghost?s switch has been removed in favor of more durable push-buttons in shielded locations by the main strain relief. A special limiter circuit gives you a smooth reduction at excess volume levels, unlike other noise-inducing clipping effect, the Ultimate limiter can be disabled with the touch of a button. Additional new features are an industrial grade nylon 6/6 strain relief at a new neck-hugging angle. This reduces stress on the cable and helps it fall closer to your body for fewer branch snags in the most rugged terrain. Material: Metal
