Using the free Bose Connect app (iOS/Android) you can display accurate heart rate readings in real time, and store historical info, so you can measure and maximise your exercise regime. The Pulse technology also works with other popular fitness apps. Focussed Sound With Bose's signature touch, you'll get a broad soundscape with deep and natural lows that engulf your senses. Also, the brand's volume-optimised EQ keeps the sound crisp no matter how loud you play it. So, there'll be no limits to your playlist. Brilliant Wireless Do away with tangled cables and pair your SoundSport Pulses to your smart device through Bluetooth or NFC. Just loop the pair around the back of your neck, pop them in your ears and do your workout without inhibition. Pair quickly through Bluetooth, or, with NFC, connect them to your smart phone with a tap. Intensely Stable Even during the most intense exercise regimes, the StayHear + tips (supplied) will conform securely and comfortably to your ear shape so they'll never leave your side. Using hydrophobic acoustic cloth, the headphones are even sweat-and weather-resistant so they are ideal for wearing indoors or out. Easy Switching The SoundSport Pulse headphones feature a 3-button inline remote which lets you switch between calls and music with one-touch ease. You can control your music too - skip a track with the press of a button. Bose Connect App As well as being able to monitor and record your workout, you can use the Bose Connect app to link up multiple Bluetooth devices and switch between them seamlessly. For example, if you're listening to music on your iPad and you get a call from your iPhone, switching over is super-easy. The app also gives you access to software updates, product tips and sound settings. Sport Inspired Case A lightweight and durable case is provided for convenience. It has been designed to store your headphones when they are not in use, and also provides a safe place to keep your keys during exercise.
