Welcome back to the Even Insider.
In the first chapter of this series, we looked inward, at the invisible systems that define how Even G2 behaves under load: wireless architecture, synchronization logic, and the foundational engineering that makes the device stable.
This entry shifts the perspective outward.
The changes covered here are easier to spot, but no less deliberate. They live in the parts you touch, wear, and look through. The display, the sensors, and the supporting hardware that quietly determines long-term reliability. Rather than pushing new features for the sake of novelty, the goal was to strike a balance of utility and comfort that lets the technology fade into the background. This is how we shaped Even G2 from the outside in.
Optics Revamp: Thinner system, wider view.
The optical module is the defining constraint of smart glasses. While most devices rely on off-the-shelf optical engines that force a bulky form factor, we refused to settle for standard industry parts for Even G2.
Since our priority was to have a pair of true everyday glasses, form factor came first - meaning weight, size, and comfort had to lead. We engineered a proprietary optical stack that is about 45% smaller than comparable public models, all while maintaining the necessary brightness. Through this, we dramatically shrank the optical engine housing. This made the overall design much sleeker, eliminating the need for a large, bulbous temple area, & keeping the product light.
We paired this compact engine with a redesigned lens architecture. We thinned down both the waveguide and its refractive layers, even eliminating an air gap present in the previous design by introducing a subtle curvature in the lens.
In practice, this means the lenses are 30% thinner and can offer better light passthrough. The result is both a physical and visual upgrade for Even G2. Physically, the glasses are lighter and slimmer, making them comfortable for all-day wear. Visually, the optimized optical path delivers a wider field of view with reduced distortion, allowing the digital overlay to blend more naturally with the real world.
Sensor Upgrade: Clear input, consistent output.
For a device to be truly "smart," it needs to understand both its environment and its user with absolute precision. We overhauled the sensor array in Even G2 to capture cleaner data, which in turn yields more predictable outputs.
A major change was doubling the microphone count from two to four. This quad-microphone array isn’t just about increasing input volume - it’s about directionality and noise filtering. With four mics spaced strategically, the system can better isolate the wearer's voice from background noise. The immediate benefit is higher fidelity voice commands and clearer audio input even in noisy environments. Just as importantly, this lays the foundation for future voice features.
We also upgraded the Inertial Measurement Unit (IMU) by adding a geomagnetic sensor (compass). This gives the glasses a precise sense of heading and orientation relative to the Earth's magnetic field - crucial for accurate navigation and spatial awareness.
Together, these sensor improvements enhance Even G2's ability to reliably interpret movement and sound. These hardware changes are subtle and don't alter the outward design, but they are deliberate in improving the experience. Their true value will become evident as software taps into them. Even G2 planted the seeds for smarter interactions; now it’s about leveraging them on the software side to deliver the best experience.
Structure Refinement: Quiet changes, lasting reliability.
The final layer of our “outside-in” approach is durability - not as a spec, but as something you feel over months of daily use.
To make Even G2 tougher without making it heavier or more industrial, we moved to a magnesium-titanium frame. The material upgrade allows a slimmer profile while improving strength and flex resistance where glasses take the most stress. We also fully enclosed the flexible printed circuit (FPC) inside the temple. On Even G1, portions of the wiring were partially exposed and more susceptible to humidity, sweat, temperature shifts, and long-term wear. On Even G2, it’s sealed within the structure, helping the device stay consistent across climates and activities.
The same thinking guided the charging case. A wearable’s reliability ends when it runs out of power, so we rebuilt the case around uptime and ease of use. We moved from wireless charging to a pogo-pin system with magnetic alignment - a simpler mechanism, but one that’s more efficient and more predictable. The magnets guide the glasses into position, so contact is secure every time.
Inside the case, we increased the battery reserve to support about 7 full charges, and improved charging speed to be ~2.5× faster than the previous generation. We also incorporated user feedback into the physical design: docking no longer depends on folding the temples in a specific order.
These changes aren’t meant to stand out on their own. Together, they make Even G2 easier to live with - more durable in the frame, more dependable in the charge cycle, and more stable in the long run.
What’s Next?
The changes described here are not meant to be noticed individually. A thinner optical stack, higher-fidelity inputs, and quiet structural improvements don‘t announce themselves in isolation. Their value shows up over time, in how the system holds together during daily use.
This "outside-in" work builds on the internal rebuild covered in the first chapter. Stable connectivity enables dependable input. Reliable input allows the system to stay predictable. Predictable systems give design and software the room to stay simple.
In the next entry, we’ll move away from hardware entirely. We will focus on Software Design Evolution: how older interaction patterns were retired, how new ones were unified, and how Even G2's OS was shaped. Bit by bit, pixel by pixel.
