Active Dynamic Balance Drivers: Dynamic Balance is Polk Audio's patented advanced analysis of a speaker's entire electro-acoustic and mechanical system. It helps Polk to select better materials and more efficient geometry. With deep analysis, Polk engineers can pinpoint and eliminate things that reduce performance before they become a part of the finished product. The miniature polymer drivers in UltraFocus Series headphones are specially tuned to produce a flat, uncolored frequency response. This true transparency reveals a wide dynamic range, with sharp details, and no hint of strain. The UltraFocus 6000 employs Active Dynamic Balance drivers made of lightweight, durable PET material, in a sealed micro-enclosure, tuned and fitted to eliminate resonances with optimized damping. Active Dynamic Balance technology is an exclusive combination of ANC (Active Noise Cancelling) and Polk's patented Dynamic Balance material tuning process.

Optimized Active Noise Canceling: Active Noise Canceling technology uses sophisticated audio algorithms to silence distracting outside noise. Polk goes one step further with UltraFocus headphones. They use Optimized Active Tuning to work in tandem with the ANC technology, enhancing audio performance beyond that of ordinary headphones. Whether you're traveling by airplane, train, or bus; walking along a busy street; or working out in the gym Polk's new UltraFocus Active Noise Canceling Headphones give you a refuge from all the noise. They deliver the kind of audio performance you expect from a home audio system; expansive, detailed, engrossing, with deep bass response.

Push-to-Hear Ambient Control: You can instantly mute audio and amplify outside sounds so you can experience the outside world without removing the headphones. The "Pus-to-Hear Ambient Control" is found on the headphones in-line controller.

Battery Powered: A single AAA battery (included) provides between 40-60 hours of listening time. The battery is inserted to the headphone's in-line controller.

Multiple Ear Tips: Properly fitted ear tips help you to eliminate extraneous noise, experience greater bass response, and enjoy better tonal balance. Ear tips that fit correctly also feel more comfortable. No two person's ears are exactly the same, so Polk includes three pair of Stayfit Silicone Tips (s/m/l), two pair of Stayfit 3-Flange Silicone Tips (s/l), two pair of Memory Foam Tips (s/l).

Ultra Flexible Tangle-Free Planar Audio Cable: Standard round headphone cables always coil up and twist; and are a constant source of annoyance, because they get in the way of your workout. Eventually repetitive twisting means the cable will break or pull out at the end. The cable's planar design (with oxygen-free wire for better conductivity) completely eliminates coiling, so the headphone cables won't tangle up during a workout, or when stored away. The planar design also eliminates micro-phonics, the tendency of an electronic device to turn a mechanical vibration into "noise," which you would hear, in this case, through the headphones.

StrainGuard: Headphones get a lot of abuse. The UltraFocus Headphones have been designed with this in mind. StrainGuard is a protective system that addresses the areas where many headphones fail most often. A Kevlar core that houses the speaker wire provides extra tensile strength to prevent the wire from being pulled apart at common failure points. The other points of common failure in headphones are at transitional points between cable lengths and at connection points. In the UltraFocus Series, all transitional connections are computer designed to strengthen the points where they fail most.

Connectors & Adapters: The UltraFocus Series headphones employ a gold-plated 3.5mm connector that has been designed to fit through the opening on most portable audio player cases. A 2.5mm adapter is also included for select mobile devices, such as Nokia. In addition, an airplane adaptor is included to use during your next flight.

Carrying Case: The Polk UF6000 comes with a convenient travel case for storage and transportation.
