Product Details

Key Selling Points in One Sentence: 

Featuring a 316L antibacterial stainless steel all-metal body, equipped with an LC12S PPG sensor and a BMA510 motion sensor, integrating 24-hour health monitoring and multi-device touch control, 5ATM waterproofing + 25-day standby time, redefining the "practicality" and "convenience" of smart wearables.


Core Value Analysis:

1. Precise Health Protection Around the Clock

Equipped with an LC12S professional PPG sensor, enabling continuous 24-hour heart rate and blood oxygen monitoring. Combined with a CT7112 body temperature sensor, it can capture real-time body temperature fluctuations and trigger vibration alerts for abnormalities (such as high/low heart rate, insufficient blood oxygen), providing early warning of health risks.


The built-in sleep analysis system not only records light sleep, deep sleep, and REM cycles, but also generates a sleep quality assessment report. Combined with daytime activity data (steps, distance, calories), it provides personalized health improvement suggestions.


It supports offline storage of one week's health data, continuing to record even without an internet connection. Once connected, it automatically syncs to the AIZO RING APP, providing flexible and uninterrupted data management.


2. Multi-Scenario Touch Control Experience Innovative multi-directional touch functionality allows direct control of eight major short video platforms, including Douyin, TikTok, and YouTube, enabling operations such as "switching videos" and "liking," freeing your hands and making video viewing more convenient.


It covers high-frequency scenarios such as e-books, music, and slideshows, supporting e-book page turning, music playback/pause/song skipping, and PPT switching, eliminating the need to frequently pick up your phone while working, reading, or entertaining.


It supports an SOS emergency call function; a long press on the touch area triggers it, allowing for quick contact with emergency contacts in critical moments, adding an extra layer of safety.


3. Ultra-thin and Lightweight Wearing Experience

The inner and outer rings are crafted from 316L antibacterial stainless steel, offering both rust prevention and antibacterial properties. Long-term wear is less likely to cause skin allergies, making it especially suitable for sensitive skin. The metallic finish enhances the sophistication of everyday wear, making it suitable for both business and casual occasions.


The device measures only 7.5mm × 2.5mm (width × thickness) and weighs a mere 5.2g, lighter than a regular coin, achieving a "feel-free" wearing experience. There is no discomfort during sleep, exercise, or work.


It offers eight US standard sizes (#6-#13, covering inner diameters of 16.5mm-22.3mm). Precise sizing ensures a stable and comfortable fit for users with different finger sizes, preventing it from becoming too loose or too tight.


4. High Efficiency and Durability Guaranteed


Equipped with a 17mAh high-density lithium polymer battery, it can last for 4-6 days with 24 hours of continuous wear and up to 25 days on standby. The magnetic contact charging design allows for a full charge in just 1 hour, enabling quick recharging during short breaks.


Supports BLE 5.4 low-power Bluetooth technology, offering a longer connection range (up to 10 meters) and faster transmission speeds, while reducing power consumption by 30% compared to its predecessor, balancing connection stability and battery life.


5ATM waterproof rating (50 meters depth), suitable for swimming, showering, and diving, eliminating the need for frequent removal. Certified by multiple countries including FCC, CE, and CCC, ensuring product quality and safety meet mainstream global standards.


A Variety of Daily Health Management Scenarios

Scenario 1: Heart Health Protection for Middle-Aged and Elderly Individuals (For middle-aged and elderly individuals concerned about cardiovascular health and with underlying conditions such as hypertension/hyperlipidemia)


Scenario 2: Stress and Sleep Management for Working Professionals (For urban white-collar workers in high-pressure work environments and those who frequently stay up late)


Scenario 3: Exercise and Body Composition Management for Fitness Enthusiasts (For fitness enthusiasts concerned about body fat percentage and exercise effectiveness)


Scenario 4: Menstrual Cycle Management for Female Users (For women who need to record their menstrual cycles and are concerned about endocrine health)
