Achieving peak fitness isn't just about the amount you exercise, it's also about the level of intensity, and keeping your heart rate in the target zone is key. Many athletes and avid runners use heart rate monitors when training to find their "sweet spot" — cardio feedback informs them of their actual exertion so they know when to push harder, and when to ease back. But wearing a chest strap and carrying yet another device is cumbersome and inefficient. That's why SMS Audio partnered with Intel® to develop BioSport — biometric earbuds that deliver professionally tuned audio for crisp vocals, tight bass and dynamic mid-tones, while accurately monitoring your heart rate! Used by premier athletes like Rob Gronkowski and surfer Alana Blanchard, the built-in optical sensor measures the smallest changes in blood flow through the capillaries inside your ear for spot on cardio tracking throughout your workout. Simply plug the gold-plated audio jack into your smartphone for all the power you need (no batteries or charging required) and discover your ideal workout zone, and when it's time to kick it up a notch. Three click MIC on the tangle-free, flat cables play/pause and answer/make phone calls — provides audio read out on current and average heart rate at every split. IPX4 water resistance protects against sweat and rain. You don't have to be an elite athlete to get your heart racing for a safe and effective workout with BioSport! Compatible with Runkeeper (1 month free) and other leading fitness apps. Includes 3 sizes of gel ear tips with stabilizing wings to ensure comfortable fit. Includes protective zip carry case. Compatible with iPhones up to 6+.
