The UltraFocus 8000 produces a truly amazing sound as easily on an airline or busy city street, as it will at home in front of your stereo system.

Polk's patented Dynamic Balance driver technology, in combination with active noise canceling and passive noise isolation, produces an audiophile-grade listening experience.

In addition, an on-ear 3 button remote control and an in-line microphone enable you to use iPod, iPad and iPhone anytime, anywhere.

There's also push-to-hear ambient control that mutes the audio and amplifies outside sounds, so you can hear those around you without removing the headphones.
