Welcome to Your CRI-600s

Let's get you listening. Most people are paired and in their first session in under two minutes.

1. Turn them on. Hold the center power button for about 3 seconds until you see the red and blue lights alternating. You'll hear a soft tone. They're awake and looking for your device.

2. Find them on your phone. Open Bluetooth settings on your phone, tablet, or computer. Look for CRI-600 in the list of available devices. Tap to connect.

3. That's it. Press play. The light turns solid blue when you're connected. Open your Holosync track, your favorite music, or whatever you love to listen to. You're ready.

First time? We recommend starting with a familiar Holosync track at low-to-medium volume so you can experience the difference these headphones make.
