Description
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.
8. IP54 Dust & Water Resistance
IP54-rated protection safeguards the earbuds against sweat, dust, and light rain, making them suitable for workouts and outdoor activities.
