20-200 mmHg
Type-C charging
1-year warranty
- Four independent pressure zones covering the eye area, temples, and rear head contact points.
- Detachable washable blue lining, adjustable nose support, and glasses-compatible wearing structure.
- Built-in battery and Type-C charging port, supporting charging while the product is in use.
- External pneumatic host can be placed on a table, in a pocket, or temporarily attached to Velcro when hands are occupied.
- Tube routing and storage are designed for a cleaner user experience and reduced noise transfer.
Flexible Wearing Modes
- Eye coverage mode: for relaxation, sleep preparation, and short work breaks.
- Reverse forehead mode: supports alternate wearing when forehead pressure or back-head pressure is preferred.
- Exercise fit: anti-slip wearing stability for light movement and post-exercise recovery routines.
- Neck heating mode: soothing warmth support with adjustable wearing position.
- Glasses compatible: structure leaves space for glasses in supported wearing scenarios.
Design Highlights
- Precision acupoint-oriented pressure layout.
- Ultra-quiet pneumatic operation with separated host and tube routing.
- Adjustable speaker position and integrated audio feedback.
- Patented product concept and proprietary control design.
- Modern brown edition surface finish for a softer consumer wellness identity.
Preset Programs
Seven intelligent modes tuned for different usage scenes.
| Mode | Pressure | Volume / Intensity | Heat | Time |

Key Control Interface
The power key supports long-press power on/off and short-press mode switching. The function key cycles through main pressure, side pressure, heating level, pressure hold time, release time, treatment time, and other parameters. The plus and minus keys adjust the selected function level.
Control Range
- 20-200 mmHg adjustable pneumatic pressure.
- Two built-in pressure sensors for 10 mmHg step control.
- 0-100% volume and heating adjustment.
- 1-10 second pressure hold and release duration.
Audio & Voice
- Bluetooth music connection via Xianglong4251.
- Hands-free calling with built-in microphone and speaker.
- Six built-in light music tracks.
- Voice control and audio prompts for main operations.
- Analog voice amplifier design for low background audio noise.
