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
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
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.
