Xiaomi OpenWear Stereo

Open-ear freedom and long-lasting comfort have been engineered into the Xiaomi OpenWear Stereo, delivering immersive sound while keeping users aware of their surroundings. A lightweight 9.6g earbud design with soft, skin-friendly liquid silicone ensures pressure-free wear throughout the day. The flexible nickel-titanium memory alloy ear hook has been constructed for durability and stability, maintaining a secure fit even during movement or workouts. A sleek, transparent profile reduces interference with glasses and enhances overall comfort for extended listening sessions.

High-resolution audio performance has been achieved through a 17×12mm super-linear dynamic driver with a DLC (Diamond-Like Carbon) diaphragm for improved sound precision. Rich treble detail, balanced mids, and powerful bass are delivered through optimized low-frequency enhancement algorithms and dynamic range control. LHDC high-definition codec support enables up to 96kHz HD audio on compatible devices, meeting Hi-Res Audio Wireless standards. An independent 10mm sound leakage reduction driver emits anti-phase sound waves to maintain call privacy beyond 25cm, while dual microphones with AI noise reduction ensure clearer communication in busy environments.

Key Features & Benefits

1. Open-Ear Lightweight Comfort

A non-intrusive open design allows ambient awareness during daily activities, office work, or outdoor exercise. Each earbud weighs approximately 9.6g, ensuring reduced fatigue during prolonged wear.

2. Flexible Memory Alloy Ear Hook

A nickel-titanium memory alloy wire has been embedded within the ear hook for enhanced durability and flexibility. After 5,000 bending tests (internal lab data), structural reliability and stable fit have been maintained.

3. 17×12mm Hi-Res Dynamic Driver

A large super-linear driver with DLC diaphragm improves clarity and audio accuracy. Bass depth is enhanced through a dedicated low-frequency algorithm, while real-time dynamic range control balances high, mid, and low frequencies.

4. LHDC Hi-Res Audio Wireless

Support for LHDC codec enables high-resolution 96kHz audio streaming on compatible Xiaomi devices, ensuring richer detail and reduced latency.

5. Independent Sound Leakage Reduction

An integrated 10mm leakage reduction driver actively emits reverse-phase sound waves, helping to keep conversations and music private at distances beyond 25cm (under tested conditions).

6. AI Noise-Cancelling Calls

A dual-microphone array combined with beamforming algorithms accurately captures voice while minimizing environmental noise for improved call clarity.

7. Extended Battery Life

Up to 7.5 hours of playback on a single charge and up to 38.5 hours with the charging case are supported, ensuring reliable performance for daily use.

8. Smart Connectivity & Controls

Bluetooth® 5.3 connectivity provides stable wireless performance within a 10m range. Smart touch controls support play/pause, call management, and customizable gestures through the Xiaomi Earbuds app. Audio sharing and Xiaomi HyperOS device integration enhance ecosystem connectivity.

9. IP54 Dust & Water Resistance

IP54-rated protection safeguards against sweat, dust, and light splashes, making the earbuds suitable for workouts and outdoor activities.
