The Sport Pulse Wireless ear buds from Jabra are wireless, have premium sound and other features similar to other high-end ear buds. But these can actually measure your heart rate through the ear buds, and transmit that information back to your phone, for use in their tracking app.
Measuring heart rate has been traditionally done through a chest strap, but new wireless technologies are starting to change that, and very fast. Also in ear phones, SMS Audio can do the same thing, and Lifebeam can measure from your helmet. Jabra promises more than just measuring the heart and playing music…
Jabra says the structural elements of the ear buds are made from carbon fiber, and are completely sealed and waterproof, so that you can use them in any conditions. They took the training and heart rate measurement seriously, working with Campbell University in North Carolina to calibrate the ear buds to a 99.2% accuracy when measured against an electrocardiogram. Jabra says one of the best advantages of the entire system is that you can control your workout and your music from one single app.
The Jabra Sport Life app can help you plan, track and evaluate your workout. There are features to set goals such as distance, calories burned or time, and the ability to set heart rate training zones, giving audible feedback if you go outside of that zone. The app will work on iOs and Android devices.
Wireless earphone technology has been a challenge for sports-minded companies, as there must be a battery to power the devices. The Sport Pulse Wireless’ have the left and right ear buds connected to each other, with a USB rechargeable battery in between. Also in the unit is a triaxial sensor that can actually detect how you are moving, sending this information wirelessly to the app. There are not a lot of details available, but the heart rate is measured similarly by a sensor in one of the ear buds. All of this, and the music is communicated with your device via Bluetooth 4,0.
