The Polk Audio UltraFocus 6000 are advanced in-ear Active Noise Cancelling headphones.

Unlike other ANC headphones, Polk has engineered an Optimized Active Tuning system that works in tandem with ANC technology to boost headphone performance into the realm of the astonishing. 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 Polk's high performance sound technology, the nearly weightless UltraFocus 6000 can really put you in “The Zone.” And with custom fitted in-ear silicone ear pieces, the UltraFocus 6000 feels much better than jamming home audio speakers into your ears.
