ACEFAST W10 In-Ear Earbuds For Sleep

Side-Sleeper Optimization: Built with a microscopic, ultra-low-profile physical housing that sits entirely flat within your ear concha. This design eliminates painful pressure points on the ear canal when your head is pressed directly sideways against a pillow.

Dimensions & Weight:

• Earbud Size: 21 × 17 × 18 mm

• Charging Case Size: 66 × 38 × 26 mm

• Total Combined Weight: 44 grams

Premium Materials: Made from premium ABS plastics paired with ultra-soft, medical-grade silicone gel ear tips to prevent skin irritation over long periods of overnight wear.

Waterproof Rating: Rated IPX4, making the outer chassis completely resistant to night sweats or accidental liquid splashes.

Dual Noise Control Network: Uniquely combines deep physical passive sealing with an onboard digital processor:

Active Noise Cancellation (ANC): Delivers a specialized -20dB noise reduction depth specifically tuned to erase low-frequency nighttime disruptions like heavy snoring, loud air conditioning hums, or traffic.

Environmental Noise Cancellation (ENC): Employs an intelligent single-microphone ENC algorithm to isolate human vocals if you need to take an unexpected phone call while in bed.

Tri-Tier Acoustic Modes: The onboard firmware allows you to easily switch through three distinct ambient sound modes: ANC On, Transparency Mode (for hearing alarms or family members), and ANC Off.

Micro-Driver Acoustic Array: Engineered with tiny 5mm dynamic drivers (16Ω impedance). This compact driver architecture keeps the outer shell incredibly small while reproducing clear audio profiles across both high and low frequencies.

All-Night Endurance: Programmed with specialized Deep Sleep Mode firmware that stretches the continuous playtime of the earbuds up to 9 hours on a single charge. This ensures you get a full night of uninterrupted audio without annoying "low battery" voice alerts waking you up.

Power Cell Capacity: Each micro-earbud houses a 37mAh battery, while the protective storage case holds a 400mAh battery.

Total System Playtime: The charging case delivers up to 3 full recharges for both earbuds, extending total independent uptime.

Charge Port & Flash Charging: Charges via a standardized USB-C interface. It takes 1.5 hours to fully charge the earbuds and 2 hours for the case. It also features a quick flash-charge configuration where a 10-minute plug-in yields 1 hour of playback.

Next-Gen Wireless Protocol: Powered by the ultra-efficient Bluetooth v6.0 standard operating on a 2400 – 2480MHz frequency band. This maintains a steady, lag-free 10-meter operational range, preventing audio drops even if your smartphone is charging on a distant nightstand.

Audio Codecs: Natively decodes audio streams via high-fidelity SBC and AAC protocols for universal cross-platform support on both iOS and Android.

Smart App Eco-System: Pairs seamlessly with a dedicated ACEFAST mobile companion application, giving you immediate access to personalized sleep timers, fine-tuned EQ profiles, and real-time battery monitoring.
