The UltraFocus 6000i, made specifically for iOS devices, is the most advanced in-ear canal Active Noise Canceling headphone available. Unlike other ANC headphones, Polk has engineered an Optimized Active Tuning system that works in tandem with ANC technology to boost headphone performance to an astonishing level. It creates an interior "soundstage" that is the closest you can get to the performance of a full-on home audio system. With two complementary noise canceling technologies, coupled with Polks high performance sound technology, the nearly weightless UltraFocus 6000i will really help you tune out the world and tune in your music. And with custom fitted in-ear silicone ear pieces, the UltraFocus 6000i feels much better than jamming home audio speakers into your ears.
