Work out smarter with the LifeBEAM Vi AI Personal Trainer Headphones in matte black. These around-the-neck headphones use a cloud-based AI coaching engine called Vi to give you real-time guidance as you run, walk, or cycle based on an internal gyroscope, accelerometer, barometer, and heart rate meter. Vi listens to commands as you work out and responds audibly, giving you information about your speed, heart rate, elevation, cadence, distance, goals, and more. Location data is gathered through its Bluetooth LE connection to your smartphone. Powered by Harman Kardon, the headphones stream music from your mobile device and enable you to take calls.
The sweat- and water-resistant earbuds magnetically attach to the flexible neckpiece, which has buttons to control Vi, volume, track forward/back, calls, and power. It lasts up to eight hours on a single charge, with four to six hours expected for normal use. Recharging is accomplished through a cap on the neckpiece. Vi can give you feedback using the Vi Fitness App for iOS and Android, which also lets you set plans and customize your headset. It also integrates with a variety of fitness apps and its data can be exported in .tcx format. Five sizes of eartips and three sizes of fins are included to help you find a comfortable fit. A charging cable and case are included as well.
