In-ear EEG sleep insights
In-ear EEG provides a more direct data source for sleep-stage analysis and overnight reports. Visual reports clarify sleep patterns and support quantitative analysis, trend comparison, and long-term tracking.
In-ear EEG · TWS sleep earbuds
The world’s firstin-ear BCI sleepbuds
PSG-benchmarked EEG monitoring meets adaptive, personalized sleep support in one compact pair of earbuds—made for high-quality sleep and effortless days.
World-leading In-ear EEG sleep staging benchmarked against PSG
All-night Continuous EEG recording
Personalized Adaptive support across different sleep states
Zero pressure Low-profile design for side sleeping
01 · Our advantages
Three advantages. One seamless system
In-ear EEG sensing, adaptive closed-loop support, and a day-to-night design come together in one seamless experience.
Adaptive closed-loop support
EEG monitoring and adaptive sleep intervention work together in a closed loop, allowing sleep support to respond to changes in your sleep state rather than follow a preset schedule.
One device, day and night
Designed for comfort across sleep positions, the low-profile in-ear form brings together overnight monitoring, personalized sleep support, and everyday wireless listening.
02 · Product functions
One system, from lights-out to wake-up
EEG monitoring, responsive audio and everyday listening cover the complete sleep journey and daytime use.
EEG sleep monitoring & reports
EEG signals support sleep-stage analysis, visual sleep architecture and long-term trend reports.
Adaptive sleep support
Audio recommendations and intervention timing respond to current EEG signals and longer-term feedback.
Sleep-onset fade-out
Audio gradually fades once sleep onset is detected, without requiring a preset playback duration.
Everyday TWS earbuds
Music, calls and everyday listening remain available during the day.
One-tap sleep mode
Monitoring and sleep-support workflows start together with a single action.
Private in-ear alarm
A gentle personal alarm is designed to wake the wearer without disturbing a partner.
03 · Core highlights
Five highlights, designed for sleep
Highlight 01 · Featherlight
A compact body that nests fully inside the concha
The rounded bean-shaped form follows the ear’s natural geometry, reducing protrusion and pillow pressure while helping the earbuds stay in place overnight.
Highlight 02 · EEG monitoring
Multi‑channel in‑ear EEG, benchmarked against PSG
Flexible electrodes capture in-ear EEG signals while balancing contact quality and comfort in a miniaturized acquisition module.
- 15 mm × 0.8 mm multi-channel acquisition module
- Data synchronized every 30 seconds
- Continuous recording designed for an eight-hour night
Highlight 03 · Sleep intelligence
Understand every night. See how your sleep is changing
Real-time data sync turns in-ear EEG into a clear sleep score, stage breakdown, and weekly trend—then uses those patterns to shape personalized insights.
- Sleep score with Wake, Light, Deep, and REM structure
- Weekly trend reports reveal progress over time
- Personalized insights turn patterns into next-step guidance
Highlight 04 · Responsive fade-out
Audio follows the moment sleep begins
When sleep onset is detected, playback fades gradually so the experience follows the wearer’s actual sleep state.
- Sleep-aware timing
- Gentle, gradual fade-out
Highlight 05 · Day-to-night
One device, from day to night
The same low-profile earbuds move naturally from music, calls, and everyday listening by day to EEG monitoring and personalized sleep support at night.
- Music, calls, and everyday listening by day
- Monitoring and sleep support by night
04 · Technology
A complete EEG pathway in a compact form
The product design connects acquisition hardware, signal quality and sleep-stage algorithms in one verifiable chain.
Miniaturized acquisition
A multi-channel in-ear EEG module measures 15 mm across and 0.8 mm thin, with flexible electrodes designed for stable overnight contact.
In-ear impedance ≈ 8.9 kΩ · filtered SNR 18.46 dBFive-stage sleep analysis
A proprietary neural network classifies W / N1 / N2 / N3 / REM using the in-ear EEG signal pathway.
78.0% accuracy · Kappa 0.70Closed-loop personalization
EEG data is synchronized every 30 seconds so intervention timing can respond to sleep progression and learn from repeated use.
30-second data cycle · low-latency feedback05 · Scenarios
