The Newest Technology 
No More Choppy playback, weak batteries, dropped phone calls... Not all Bluetooth headsets are created equal! Bluetooth 4.1 increases Battery Life dramatically while letting you travel further than ever before. 
The Easiest Way to Manage Battery Life. 
Our new LifeStateTM technology interfaces with Apple iOS and latest Android devices to show you at a glance how much battery life is left in your headset. 
The Highest Audio Quality 
The X11 uses the highest quality transducers and hardware, as well as Bluetooth 4.1, and A2DP stereo transfer protocols. That means bigger bass, lighter-than-air treble, and perfect phone call clarity EVERY time. 
The Most Revolutionary Feel 
We designed the X11 so that it's an extension of your own body. It's sturdy and comfortable, but lightweight and super sweat-resistant... making it the perfect solution for home, gym, work and traveling.
