Most smart glasses suffer from a fatal flaw: video footage that shakes like an earthquake scene (the dreaded “Jelly Effect”). The W620 has clearly heard the feedback. Weighing in at an ultra-light 37g, its biggest upgrade is jamming EIS (Electronic Image Stabilization) into the frame, powered by the context-aware Tongyi Qianwen (Qwen) LLM.
If you need a “stabilized recorder” and “walking encyclopedia” that you can wear 24/7, the W620’s dual-chip architecture (Jerry JL7018F + Allwinner V821L2) delivers a calculated, high-performance experience.
Vision Evolved: EIS & The Privacy “Red Line”
Let’s address the biggest pain point first: EIS Stabilization. The W620’s 8MP camera (interpolated to 32MP) isn’t just about pixel count; it’s about dynamic displacement compensation. In real-world tests like walking or cycling, the footage no longer tears or jitters. It delivers smoothness comparable to an action camera.
Another detail deserving praise is the “Indicator Light”. To address legal and ethical concerns regarding privacy, the W620 features a persistent light while recording. While this might seem like a restriction, it’s a sign of a mature, compliant product. It allows you to use the device in public spaces not as a “spy,” but as a transparent creator.
Brain Transplant: The Insight of Tongyi Qianwen
Unlike its predecessors, the W620 connects to the Tongyi Qianwen (Qwen) Large Language Model. The difference is palpable—it understands context deeply. When you stare at a piece of calligraphy or a houseplant and ask, “What is this?”, it doesn’t just label the object. It acts like a museum guide, explaining the cultural style of the font or care tips for the plant.
Audio & Connectivity: ENC & Instant WiFi
On the audio front, the W620 upgrades to ENC Dual-Mic Noise Cancellation. Intelligent beamforming filters out street traffic and crowd noise precisely. Taking a Bluetooth call in a noisy cafe proved that the voice on the other end remains pure, with background chaos virtually eliminated.
Finally, it retains the series’ best feature: WiFi Transfer. Instead of waiting ages for Bluetooth, your 4K photos or stabilized videos beam directly to your phone via WiFi, making social sharing instant.
👉 The Verdict: The W620 is a pragmatist’s dream. It solves usability with EIS, intelligence with Qwen, and wearability with its 37g weight.
