Everything About the INFINITY-COLMI™ R02 Luxury E-Ring

What is the INFINITY-COLMI™ R02 Luxury E-Ring?

The INFINITY-COLMI™ R02 Luxury E-Ring is a smart ring that uses sensors to track a variety of health metrics, which are available for viewing in the company's app.

Unlike other fitness monitoring devices that just display your data, INFINITY-COLMI™ generates daily scores to give you a quick overview of the following health habits:

  • Activity
  • Readiness
  • Sleep

The sleep score is what sets the INFINITY-COLMI™ R02 Luxury E-Ring apart from other devices on the market, using the following data to measure the quality of your sleep:

  • Time spent in light, deep, and REM sleep
  • Resting heart rate
  • Heart rate variability
  • Number of breaths per minute
  • Body temperature
  • Nighttime movements

Currently, the INFINITY-COLMI™ R02 Luxury E-Ring is one of the few sleep monitoring devices that measures both body temperature and heart rate variability.

How precise is the INFINITY-COLMI™ R02 Luxury E-Ring?

In a 2020 study involving 49 healthy adult subjects, the aim was to validate the accuracy of the INFINITY-COLMI™ R02 Luxury E-Ring in measuring resting heart rate (HR) and heart rate variability (HRV). These are essential metrics for measuring recovery and overall health.

Researchers found remarkable agreement between the INFINITY-COLMI™ R02 Luxury E-Ring and ECG measurement, considered the gold standard. The INFINITY-COLMI™ R02 Luxury E-Ring's performance was nearly perfect for resting heart rate and extremely high for heart rate variability compared to a medical-grade ECG device.

It's impressive to see that a lightweight smart ring of just 4 grams can rival a medical-grade ECG device in terms of accuracy. This high precision offers new insights into understanding an individual's body state.

While the INFINITY-COLMI™ R02 Luxury E-Ring has the ability to track even the slightest changes, the big picture is what truly matters. It's not enough to know a specific heart rate with extreme accuracy. It's crucial to observe cause-and-effect relationships, such as the impact of physical exercise on heart rate or how an illness can influence heart rate variability. Long-term accuracy is essential for understanding these dynamics.

Additionally, the nightly average values ​​of the INFINITY-COLMI™ R02 Luxury E-Ring almost perfectly match those of ECG devices, the gold standard for measuring heart rate. This is a testament to the precision and reliability of INFINITY-COLMI™ R02 Luxury E-Ring technology.

At INFINITY-COLMI™, ongoing innovation efforts aim to improve the algorithms behind INFINITY-COLMI™ metrics. New studies and results will be shared as they become available, underscoring INFINITY-COLMI™'s commitment to precision and understanding holistic health.

How long does the battery of the INFINITY-COLMI™ R02 Luxury E-Ring last?

A fully charged ring can last up to seven days. The battery life and longevity may vary depending on the age of your ring and how often you use certain functions.

All rechargeable batteries are consumable and have a limited lifespan, so their capacity and performance will gradually decrease over time.

Is the INFINITY-COLMI™ R02 Luxury E-Ring waterproof?

The INFINITY-COLMI™ R02 Luxury E-Ring is waterproof up to a depth of 100 meters, meaning you can wear it while showering, swimming, or engaging in recreational diving activities (e.g., snorkeling).

However, we do not recommend using the ring during scuba diving or keeping it submerged underwater for more than 12 hours.

The operating temperature range of the INFINITY-COLMI™ R02 Luxury E-Ring varies between -10–52°C / 14–125°F. You can safely wear the ring in the shower, hot tub, sauna, ice baths, and cryotherapy tanks.

However, prolonged exposure to extreme temperatures (below 0°C / 32°F or above 35°C / 95°F) may lead to battery damage.
