Xiaomi OpenWear Stereo Pro

Premium open-ear comfort and professional-grade sound performance have been combined in the Xiaomi OpenWear Stereo Pro. Designed with a lightweight open-ear structure, all-day wearability is supported through a secure three-point ergonomic fit and flexible memory titanium ear hooks. The exterior has been wrapped in soft liquid silicone, while refined materials such as nano-tech vegan leather and metallic finishes contribute to a sophisticated aesthetic. Environmental awareness is maintained through the open design, allowing surroundings to remain audible during work, commuting, or workouts.

Advanced hybrid acoustic architecture has been integrated for high-fidelity audio delivery. A custom 18 × 13mm dynamic driver with dual magnetic design is paired with dual balanced armatures and a piezoelectric ceramic tweeter, producing powerful bass, crisp highs, and detailed mids. Harman AudioEFX tuning with dedicated EQ profiles ensures professional sound calibration. Enhanced privacy is achieved through an upgraded active sound leakage reduction system that minimizes audio spill within close range. With Bluetooth® 5.4, LDAC codec support (on compatible models), AI-powered features, and up to 45 hours of total battery life, seamless connectivity and long-lasting performance are delivered.

Key Features & Benefits

1. Open-Ear Comfort with Secure Fit

A lightweight 9.7g earbud design has been engineered for extended listening sessions. The embedded 0.6mm memory titanium wire provides flexibility and stability, while the three-point support system evenly distributes pressure for enhanced comfort.

2. Hybrid Multi-Driver Acoustic System

An ultra-large 18 × 13mm dynamic driver delivers deep bass performance. Dual balanced armatures and a piezoelectric ceramic tweeter enhance treble clarity and detail reproduction, creating a wide and immersive soundstage.

3. Harman AudioEFX Professional Tuning

Two dedicated EQ profiles have been developed in collaboration with Harman experts. Multiple sound modes can be selected through the Xiaomi Earbuds app or Bluetooth settings for personalized listening.

4. Active Sound Leakage Reduction

An additional 10mm sound leakage reduction driver emits reverse-phase sound waves to reduce external audio spill. Up to 60% improved leakage reduction performance is achieved compared to previous models (internal testing).

5. Independent Built-In Recording

Audio recording can be activated even when the charging case is closed, supporting professional and on-the-go voice capture. Recordings are stored directly within the earbuds and exported via the companion app.

6. Long Battery Life with Fast Charging

Up to 8.5 hours of playback on a single charge and up to 45 hours with the charging case are supported. A 10-minute fast charge provides up to 2 hours of listening time.

7. Smart AI & Connectivity Features

AI Subtitles enable real-time translation and transcription on supported devices. Dual-device connectivity and Google Fast Pair allow seamless switching and instant pairing. Audio sharing supports simultaneous connection of two Xiaomi earbuds to one device.
