Our take on the Polk Audio UltraFit 1000 by Crutchfield's Dave Bar
Switch seamlessly between phone calls and music without interrupting your workout with Polk's UltraFit 1000 sports headphones. These versatile in-ears team high-energy sound with a durable, moisture-resistant design to match your active lifestyle. Their silicone ear tips rest gently in the outer part of your ear canals while soft, bendable ear clips keep them firmly in place no matter how tough the going gets.
Control your iPhone® or iPod® with ease
The UltraFit 1000's in-line remote lets you operate select Apple® devices while you're working out or on the go. You can answer and end calls, control your music's volume, and pause, play, or skip through your songs. Plus, a built-in microphone lets you enjoy hands-free conversations on your iPhone.
Pick the cable length that's right for you
The UltraFit 1000s include two tangle-resistant, Kevlar®-reinforced cables to match your listening style. A long 41" cable lets you wear your music player on your waist or in your pants pocket, while the short 14" cable makes a convenient connection to an iPod tucked into an armband holder or shirt pocket. Or, you can unplug the extension cables altogether, and hook the headphones straight into an iPod nano®, iPod shuffle®, or other MP3 player clipped to your shirt collar. The UltraFit 1000s come with a soft, zippered case for storage, and a clothing clip to help keep them in place while you're on the move.
Use them about 5 days a week on a treadmill @ the Y. Last set(500) lasted about 8 months. Good enough for me to buy set # 2

UltraFit Series Sports Headphone: Polk Audio designed their new UltraFit Series Sport Headphones to enhance your headphone listening experience while enduring your most demanding workouts, comfortably. The Polk Audio UltraFit Series Sport Headphones are engineered for comfort, performance, and durability. You'll appreciate how they fit and stay put even through the roughest workouts. You'll also be impressed and delighted by the dynamic sound quality of the UltraFit Sport Headphones. The UltraFit 1000 even offers an in-line remote + mic, so you can control your iPod or answer your iPhone on the go.
Dynamic Balance: Co-developed with the Johns Hopkins Center for Non-Destructive testing, Dynamic Balance is a design tool that enables Polk Audio engineers to pinpoint the elements that negatively impact driver performance. These same engineers then carefully control materials, interfaces, and geometries; resulting in a headphone with great sound.
Dynamic Balance Polymer Drivers: UltraFit Sport Headphones employ dynamic drivers much like those in a Polk Audio full size speaker; they're just a lot smaller (14.2mm). To meet Polk's predetermined performance parameters, their engineers took the same care designing these drivers as Polk Audio large speaker drivers; even adding a discrete crossover filter to each driver to naturalize the high frequencies.
Ported Enclosures: UltraFit Sports Headphones are ported, since there is the port (ear piece) you put in your ear. There are also 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.
Moisture Shield: The UltraFit 1000 headphones employ Moisture Shield to protect the headphones during your workout. Moisture Shield consists of a thin scrim on UltraFit 1000 driver screen. This filter material resists moisture that could get to the driver; so the headphones can keep performing through strenuous 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 the earpiece stays in place. With SecureFit Support, you'll experience a snug yet comfortable fit. Now, you can put your headphones on and forget about them during your workout.
3 Pairs of StayFit Eartips: Properly fitted eartips help you to eliminate extraneous noise, experience greater bass response, and enjoy better tonal balance. Eartips that fit correctly also feel more comfortable. No two person's ears are exactly the same, so Polk includes 3 different sizes (S/M/L) of StayFit silicone eartips to ensure a secure and comfortable fit for optimum audio performance.
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 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.
StrainGuard: Sports 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.
3 Cable Lengths: UltraFit Series headphones come with three cable length options, so you can wear your music device the way that works best for you. The attached 14" headphone cable lets you clip your portable music player to your shirt collar (with included shirt-clip), an included 41" headphone extension cable enables you to wear your music player on your waist or pants pocket, while the supplied 14" headphone extension cable lets you wear your iPod nano, iPod shuffle, or other MP3 players on a t-shirt sleeve.
Note: The 41" headphone extension cable is the only cable that included the in-line remote/mic.
3.5mm Connector: All UltraFit Sports Headphones employ a gold-plated 3.5mm connector that has been designed to fit through the opening on most portable audio player cases.
3-Button Remote Control + Mic: The UltraFit 1000 features a 3-button remote & microphone (located on the 41" headphone extension cable) so you can use your iPod, iPhone, or iPad on the go with in-line controls. The in-line remote lets you initiate play/pause, change tracks, adjust volume, or take a call (iPhone only) without ever touching your player. The in-line microphone supports both voice control (for iPod/iPhone/iPad) and hands-free communication (iPhone only). The UltraFit 1000 is "Made for iPod/iPhone/iPad" compatible and supports the following models and functions (as of 12/28/2011).
|iPod Model||Generation||Tested Version||Audio Output||In-Line Remote||In-Line Mic|
|3.5mm Connector||Audio Playback||Playback Controls||Answer/End Call||Voice Control||Hands-Free Communication|
Note: Apple iPod/iPhone software updates may change functionality results. If you download a newer software version, you may need to reset your iPod/iPhone to regain functionality. If this doesn't work, you may need to revert to the older software version or wait until a newer software update is available.
Moisture Resistant Soft Case: The UltraFit Sports Headphones include a moisture resistant soft case for storage, transport, and protection of the headphones and its included accessories (extension cables, in-line remote/mic, ear-tips, shirt clip).

1 question already asked
2 answers I recently just purchased these for working out. Have only worn them once, but noticed that the sound volume in my right ear piece was significantly lower than my left ear piece. It did not matter what music I was listening to at the time. I had them plugged into my iPhone 5s, which was in my pocket while I was working out. Has anyone experience difference in sound volume between the left and right sides? [ Dukie4lif May 01, 2015 ]
Sound balance is good on the set I got. You may want to return your set. [ Steven May 03, 2015 ]
No I haven't. I run in mine and occasionally I have to take the rubber ear inserts out dry them and the actual earphones out. Never notice the problem you have. [ RANDALL May 03, 2015 ]
