Redefining vision.
Reimagining everyday.
Y4 Smart Glasses Global Launch Set for August. A closer look at the engineering behind hands-free capture, AI translation and all-day wearability.
01 / The design challenge
More capability.
More capability.
Less in the way.
Smart glasses should feel natural long after the first demonstration. That means balancing camera processing, AI voice interaction, battery life and a comfortable fit.
The FancyView Y4 combines a dedicated dual-chip architecture, Sony imaging and multi-modal AI in a lightweight wearable platform.

Explore the engineering details
- JL7018F3 Main Controller + Allwinner V821 IPC Chip: The Jieli JL7018F3 main controller manages ultra-low-power daily tasks, dual-mode Bluetooth audio, and voice wake-up, while the dedicated Allwinner V821 IPC chip fires up in milliseconds only when high-bandwidth camera capture or visual AI recognition is triggered.
- Real-World Endurance from a Single 290mAh Battery: Thanks to this dual-chip + dual-system power optimization, a single 290mAh high-density battery (charged via standard Type-C) delivers up to 17 hours and 55 minutes of continuous music playback, 16 hours of continuous voice calls, or 1 hour and 20 minutes of continuous HD video recording.
- Dual Bluetooth (BLE 5.4 + BT 3.0) + Low-Power 2.4G Wi-Fi 6: To eliminate transfer bottlenecks, BLE 5.4 + BT 3.0 maintain rock-solid audio and App telemetry links, while low-power 2.4G Wi-Fi 6 kicks in ONLY when syncing captured 2K photos and 1080P/2K videos from the built-in 8GB TF storage to your phone at high speed.
- Multi-Face Ergonomic Fit & Lightweight Body: Combining an upgraded micro-optical engine with a lightweight frame and multi-face ergonomic geometry, the Y4 distributes weight evenly across the nose pads and ear bends, offering multiple colorways and finishes to match diverse daily styles.

- 8MP Sony IMX219 Sensor for 2K Photos & 1080P/2K 30FPS Video: Powered by a genuine 8-megapixel Sony IMX219 CMOS sensor and the Allwinner V821 ISP pipeline, the Y4 captures crisp 2K high-definition photos and records smooth 1080P/2K video at 30FPS.
- EIS Video Stabilization for Moving POV Shots: Because human head movements introduce natural micro-shakes while walking or interacting with family, integrated Electronic Image Stabilization (EIS) actively compensates for motion jitter—keeping first-person footage steady and natural.
- Zero-Friction Physical & Multi-Modal Controls: With 8GB of built-in TF card storage, you can snap photos or start recording instantly without a phone nearby using either the dedicated single physical button (supporting power on/off, photo snap, video recording, and reset), 3-point temple touch control, or hands-free voice commands, complete with a tri-color LED indicator for clear status feedback.

- Real-Time Dialogue Translation Across 90+ Languages: Supporting 90+ languages, the Y4 streams live two-way translation directly to your ears, breaking cross-language barriers while letting you maintain natural, confident eye contact.
- Triple 2718 Silicon Mics + Dual-Mic ENC Call Noise Cancellation & Dual Temple Speakers: The frame houses three 2718 silicon microphones paired with dual-mic Environmental Noise Cancellation (ENC) algorithms to lock onto human speech and filter out background street or café noise. Audio is delivered privately through dual 2008A-3.5mm open-ear speakers (one built into each temple arm).
- AI Recording with Real-Time Transcription & Smart Summary: During meetings or interviews, the Y4 supports AI audio recording with automatic speech recognition, real-time text transcription, and AI-generated smart summaries—turning long discussions into structured action notes.
- 24/7 Multi-Modal AI Assistant & Smart Schedule Reminders: Featuring capacitive wear detection (automatically sensing when you put the glasses on), the Y4 acts as an always-ready assistant supporting AI multi-modal visual recognition, panoramic smart search, instant Q&A, image recognition, and voice/App schedule reminders so you never miss an important appointment.

06 / Engineering FAQ
A little more
A little more
under the surface.
Why does the Y4 use both a Jieli JL7018F3 controller and an Allwinner V821 IPC chip?
Running a camera processor continuously drains wearable batteries fast. By pairing the low-power JL7018F3 for Bluetooth audio and AI voice standby with the Allwinner V821 dedicated solely to high-speed imaging and Wi-Fi 6 transfer, the Y4 smart glasses achieve 17 hours and 55 minutes of music playback and 16 hours of talk time on a single 290mAh battery.
What camera sensor does the Y4 use, and how does it handle shaky footage?
The Y4 is equipped with an 8MP Sony IMX219 sensor capable of shooting 2K still photos and 1080P/2K 30FPS video, paired with EIS (Electronic Image Stabilization) to keep hands-free POV footage smooth during daily movement. All media is saved directly to the 8GB built-in TF card and transferred rapidly via 2.4G Wi-Fi 6.
Beyond 90+ language translation, what other AI productivity features are built in?
Alongside real-time dialogue translation across 90+ languages, the Y4 features AI voice recording with real-time transcription and smart summaries, 24/7 multi-modal AI visual recognition (identify objects and ask questions on the fly), and automatic schedule reminders via voice or App.
