Polk Audio's new UltraFit Sports Headphone Series is a rethinking from the ground up of performance, comfort and durability-the three characteristics serious athletes need most in a pair of headphones. Serious music lovers too will value the UltraFit Series because of its undeniably impressive sonic performance.
The UltraFit 500 is our entry model and is designed to sit in the flange of your ear canal, while the ear piece hook insures a snug yet comfortable fit. The UltraFit 500 does not use in-line controls or a microphone, but has been designed to assure you of moderate noise suppression, so you're always aware of your environment. A short (14") cable, frees you to wear an MP3 player on a sleeve or collar for the utmost in hassle-free and tangle-free connections
UltraFit Series headphones 500 come with three cable length options, so you can wear your music device the way that works best for you. A long (41") cable enables you to wear your music player on your waist or pants pocket. The short (14") cable lets you to wear an iPod nano, iPod shuffle or other MP3 players on a t-shirt sleeve. While the headphone to 1st connector is for a shirt collar.
- Dynamic Balance Polymer Drivers and Ported Enclosure for High Performance Digital SoundCo-developed with the Johns Hopkins Center for Non-Destructive testing, Dynamic Balance is a design tool that enables the engineers to pinpoint the elements that negatively impact driver performance to carefully control materials, interfaces and geometries. UltraFit Sport Headphones employ dynamic drivers much like those in a full size speaker. They’re just a lot smaller. To meet the predetermined performance parameters, the engineers took the same care designing the drivers, even adding a discrete crossover filter to each driver to naturalize the high frequencies. And the UltraFit Sports Headphones are ported. There is the port (ear piece) you put in your ear. But the big deal is very small channels in the back of the driver enclosure, beneath the Polk logo. These 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 CableRound cables, always coiling up and twisting, 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 UltraFit’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.
- Moisture ShieldNo headphone works well in a sweat bath of moisture. So Moisture Shield is added, a filter that provides two benefits. As a thin scrim on UltraFit 500 driver screen, the filter material resists moisture that could get to the driver; the headphones keep performing through strenuous activity. Moisture Shield also provides an acoustic barrier to help smooth frequency response.
- SecureFit SupportYou’re ready for your workout. You put on your headphones and get to work. The last thing you want is for an earpiece to fall out, instantly breaking your rhythm. SecureFit Support is a flexible ear hook that wraps around your ear, so the earpiece stays in place. With SecureFit Support, you’ll experience a snug yet comfortable fit; put your headphones on and forget about them.
- StrainGuardSports headphones get a lot of abuse. UltraFit Sports Headphones have been designed with this in mind. Strainguard is a protective system that addresses the areas where sports 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 sports headphones are at transitional points between cable lengths and at connection points. In the UltraFit Series, all transitional connections are computer designed to strengthen the points where they fail most.
- Environmental AwarenessBeing aware of your surroundings is always important when you use a pair of headphones. In the gym, on the track or walking through the neighborhood, you want to be able to have a sense of what’s going on around you. The UltraFit 500 offers light to moderate levels of outside noise reduction.
