Technology & Features

Dynamic Balance® Design Technology

Dynamic Balance is our patented advanced analysis of a speaker’s entire electro-acoustic and mechanical system. It helps us select better materials and more efficient geometry. With deep analysis, we can pinpoint and eliminate things that reduce performance before they become a part of the finished product. The miniature polymer drivers in UltraFit 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.

Dynamic Balance Polymer Drivers

Drivers just like those used in full-sized loudspeaker, just a lot smaller. Designed with the same care, and the same adherence to superior performance parameters, unheard-of in headphones. Discrete crossover filters added to each UltraFit driver system naturalizes high frequencies for more lifelike sound.

Ported Enclosures. Yes, Ported Enclosures!

UltraFit Sports Headphones are ported. Small channels in the back of the driver enclosure, beneath the Polk logo, are crucial to tuning the driver's frequency response peaks. And that means a better sounding pair of headphones.

Ultra-Flexible Tangle-free Planar Audio Cable

Round cables, always coiling up and twisting, are a constant source of annoyance because they get in the way of your workout. Repetitive twisting always results in broken cables that flop out of their connection. The UltraFit Series uses a flat planar design (with oxygen-free wire for better conductivity) that completely eliminates coiling, so the headphone cables won't tangle up during a workout, or when stored away.

Moisture Shield

Located in the ear port on the UltraFit 3000 and as a thin scrim on UltraFit 500/1000 driver screen, the moisture shield filter resists moisture that could damage the driver; so your headphones keep performing through strenuous, sweaty activity. Moisture shield also provides an acoustic barrier to help smooth frequency response.

SecureFit™ Support

SecureFit support is a flexible ear hook that wraps around your ear, so your earpiece stays in place. With SecureFit support, you'll experience a snug yet comfortable fit, even during rough play. You can put your headphones on and forget about them!


StrainGuard design protects the areas where sports headphones take the most abuse. It includes a Kevlar core that provides extra tensile strength to the cables, preventing pull-aparts at common failure points, like transitions and connection points. In the UltraFit Series, all transitional connections are computer designed for perfect fit, to strengthen the points where they fail most.

Variable Noise Reduction Levels

Stay aware of your surroundings, even while getting lost in your own world. The UltraFit 500, 1000 and 2000 offer light to moderate levels of outside noise reduction. The UltraFit 3000 provides a higher level of noise reduction.

iPhone 3.5 mm Connector

Designed to fit through the opening on all cases.

Convenient 3-Button In-Line Controller

Both the UltraFit 1000 and 3000 feature a 3-button in-line control & microphone so you can use your iPhone, iPod (and iPad) on the fly. Change tracks, volume, initiate play/pause or take a call (iPhone) without touching your player. With the UltraFit 2000, you can change tracks, volume, initiate play/pause or take a call (iPhone) also without touching your player. Its built-in 3-button in-line control & microphone let's you use your iPhone, iPod (and iPad) on the fly just by touching your right earpiece.

Reflective Wrap-Around Safety Headband

The UltraFit 2000 incorporates a highly reflective wrap-around insert for additional safety and improved low light visibility.

Stylish Airframe Design

All UltraFit designs combine aerodynamics and advanced materials technology to achieve the ideal balance of performance, comfort and reliability.
