Through direct communication with your iPhone, Rayz delivers intelligent features that can be customized to your preferences—all in a small headphone. Rayz suppresses noise in your surroundings, allowing you to focus better on the things you want. It lets in just enough ambient sound for greater awareness of your environment. Remove the headphones from your ears, and the music automatically stops. Put them back in, and the music continues. With the press of a button, you can access your favorite app, mute calls, or use Rayz control functions. It’s the easiest way to get directly to the things you love. Customize your headphones and Smart Button settings. Software updates add new features. Rayz Lightning headphones are the first to automatically recognize "Hey Siri" commands, making it easy to make a call, send a message, listen to music, and much more. The microphones on the Rayz automatically mute when you stop speaking. Start talking, and they automatically turn back on. The simplest and smartest way to prevent annoying background noise from disrupting your conference calls. Lower power consumption than any other Lightning headphones. No charger or batteries required.
