Overview: The Polk Audio UltraFocus 6000i in-ear headphones
are made specifically for iOS devices. The in-line 3-button remote
control/microphone work with your iPhone, iPod, and iPad for controlling your
music, videos, and phone calls. Active Noise Canceling shuts out ambient noise,
so all you hear is your music or phone call. The UltraFocus 6000i comes with a
wide assortment of ear tips, an airline adapter, and a semi-hard storage case.
Optimized Active Noise Canceling: Active Noise Canceling
technology uses sophisticated audio algorithms to dramatically reduce distracting outside
noise by up to 15dB. ANC technology, combined with Optimized
Active Tuning, creates an interior soundstage that sounds comparable to your
home audio system. The Active Noise Canceling circuitry is powered by the
supplied AAA battery, which provides 40-60 hours of listening. In addition to
the ANC technology, the Passive Isolation technology of the sealed ear-canal
design naturally minimizes external sound while boosting bass response.
Active Dynamic Balance Drivers: The 13.6mm drivers are made
of PET, a lightweight, but durable material. These Active Dynamic Balance
drivers are sealed into a micro-enclosure, and tuned and fitted to eliminate
Push-to-Hear Ambient Control: For those times when you
temporarily want to hear external sounds, the UltraFocus 6000i's Push-to-Hear
Ambient Control will instantly mute the audio signal while amplifying outside
sounds to let you hear what's going on. This convenient control lets you hear
and carry on a conversation without having to remove the headphones. The
Push-to-Hear button is located on the in-line control module.
Attenuation Switch: The control module has a two-way switch
that allows you to attenuate the audio signal by -10dB. For normal listening,
the switch should be in the "0" position. If you are connected to an audio
source with an excessive high level, such as an airline audio jack, you can
switch to the "-10dB" position to attenuate the signal to a more listenable
Flat Audio Cable: The headphones are equipped with a flat,
flexible planar audio cable which resists tangling. The low-friction coating on
the cable helps prevent contact noise from distorting your music. The cable
features StrainGuard Kevlar core technology to prevent the wire from being
pulled apart at high strain areas. The headphones are terminated with a
gold-plated 3.5mm connector that has been designed to fit through the opening on
most smartphone and portable audio player cases. An airline adapter, with dual
3.5mm plugs, is also included.
Multiple Ear Tips: The headphones come with multiple sizes
and styles of ear tips. Properly fitted ear tips help you to eliminate
extraneous noise, experience greater bass response, and enjoy better tonal
balance. Correctly-fitting ear tips also feel more comfortable. Polk includes three pairs of StayFit Silicone Tips (small,
medium, and large), two pairs of Stayfit 3-Flange Silicone Tips
(small and large), and two pairs of Memory Foam Tips (small and large).
