Secure Headphones with Built-In Magnets
When not in your ears, keep the Bluetooth earphones together with built-in magnets. Not only do the magnets offer a way to prevent the headphones from sliding off your shoulders when not in use, they also offer a sporty, yet secure way to hold them.

H4 has the Google Assistant and Siri built in.
Play music, get answers and set a timer from everywhere-simply by double pressing the Play/Pause button.

12 Hour Battery Life with iOS and Android Indicator
Whether you're running a marathon or planning a hike, you'll have more than enough music due to the generous 12 hour battery life. When it eventually runs out, it can be fully recharged in only 2 hours. For those connected to an iOS or Android device, a handy indicator will show on your device's screen so you know your device's battery life at any time.
