CRI-500 Custom Wireless Earbuds

The only wireless earbuds designed exclusively & approved for use with Holosync!

CRI-500 Custom Wireless Earbuds are your perfect companion whether you’re listening to music, watching your favorite movie, talking on the phone, working out at the gym, scrolling through social media, enjoying an audiobook, listening to your Holosync meditations, or anything else you use earbuds or headphones for.

  • Customized Comfort

The CRI-500s include three different ear tip options so that you can enjoy the best comfort possible.

  • Active Noise Cancellation

By tuning out distractions and background noise with Active Noise Cancellation, you’ll easily lock into your Holosync meditation or any listening experience no matter where you are!

  • Transparency Mode

No need to take out your earbuds to have a conversation; just activate Transparency Mode and your CRI-500s will use the built-in microphone of your earbuds to pick up on outside noises so that you can hear what’s going on in your immediate environment.

  • The Full Range of Sound

The CRI-500s have a frequency response that goes all the way down to 4 Hz so you can reach the most potent Holosync brainwave states. Only the CRI-500s have been exclusively designed and approved for use with all Holosync soundtracks.

No other wireless option meets

our high standards.

  • Gaming Mode

Activate Gaming Mode to hear in complete 360 degrees while playing your favorite video game, while ensuring that what happens on your screen is matched by the correct sound in real-time.

  • Long Life & Quick Charge

Get up to 260 hours of standby time on a single charge and up to 20 hours of active listening time on a single case charge. The CRI-500

Charging Case contains a digital

display that lets you see your

earbuds’ battery life at a glance.

  • Intuitive Tap-Technology

Easily raise or lower volume, skip to the next track, answer or reject calls, activate noise canceling or transparency mode, and even enter low-latency “gaming mode” without having to futz around with your device!

  • Sweat & Rain Resistant

meaning they are sweat and water

resistant. You can be confident

using them anytime - even if

you just feel like singing

in the rain.
