Flavor is every vaper’s first sensory memory — and the key measure of any device’s quality.
Since our founding, YiHi has stayed true to its philosophy: “Customer first, innovation for the customer.” For us, flavor is the soul of chip development.
The Birth of SXi-Q — Effortless Multi-Profile Switching
In October 2015, alongside the launch of the SXmini ML Class, YiHi introduced its self-developed SXi-Q system.
For the first time, users could create five fully customizable profiles (C1–C5). Whether switching between different atomizers or adapting to various e-liquids, users could fine-tune settings on a PC and upload them to the device — delivering a “one device, many flavors” experience.
Intelligent Taste Curve — Drawing the Path of Flavor
In May 2016, with the debut of the SXmini Q Class, SXi-Q entered a new era with Intelligent Taste Curve (SXi-EQ) technology.
- Select SXi-EQ modein the software and choose from five flavor curves (S1–S5).
- Each curve features 20 adjustable power pointsacross a 10-second heating cycle, allowing precise control in 5-second intervals.
- From a gentle preheat to an explosive instant ramp-up, users can design their own flavor curveand save it directly to the device.
The system also offers pre-set classic modes:
- Soft: Gradual 75% → 100% power for a smooth, delicate vape.
- Hard / Strong: 125% → 100% ramp-down for instant vapor and flavor burst.
- Neutral: Balanced and consistent for all-day vaping.
Flavor Beyond Just “Good” or “Bad”
With SXi-EQ, flavor is no longer a subjective “good” or “bad” — it becomes measurable, designable, and repeatable.
Like mixology or baking, it invites vapers to be part of the flavor creation process.
This innovation set YiHi apart in the market and became a gold standard for flavor control in the cloud-chasing era.
