11mm Dual-Magnet Driver & Hi-Res Audio Wireless via LDAC
The Xiaomi Buds 4 Pro (model M2126E1) is Xiaomi's flagship in-ear true wireless audio system, housed in a space-capsule magnetic case that opens wide for effortless single-handed removal. Each 4.4g earbud incorporates a custom 11mm dual-magnet super-balance dynamic driver with high-amplitude sound-ring sub-structure to deliver deep low-frequency extension and low total harmonic distortion. Certified for Hi-Res Audio Wireless, the Buds 4 Pro supports Sony's LDAC codec at bitrates up to 990kbps and audio resolutions up to 96kHz/24-bit alongside SBC and AAC. A built-in 12nm multi-core chip and six-axis inertial sensor enable standalone Dimensional Audio with head tracking directly inside the earbuds, maintaining 360-degree spatial soundstage positioning even when connected to televisions, gaming consoles, or laptops that lack native spatial audio software.
48dB Ultra-Wideband Smart ANC & VPU Bone-Sensor Call Clarity
For noisy urban commutes and flights, the Xiaomi Buds 4 Pro achieves up to 48dB active noise cancellation depth across an ultra-wide 4,000Hz frequency bandwidth, blocking up to 99.6% of ambient background noise. Users can let the intelligent algorithm automatically switch across 3 adaptive ANC levels based on ambient noise, or manually adjust across 6 ANC levels and 3 Transparency modes (Regular Transparency, Enhance Voice, and Enhance Ambient Sound) inside the Xiaomi Earbuds app. Voice calls combine a 3-Mic + VPU (Voice Pick-up Bone Sensor) hardware array with Xiaomi's proprietary AI wind-noise reduction algorithm to isolate speech cleanly in wind speeds up to 32.4km/h.
38-Hour Total Battery, Qi Wireless Charging & Bangladesh Buyer Checklist
With ANC turned off, the earbuds deliver up to 9 hours of continuous playback on a single charge and up to 38 hours total with the charging case, while a 5-minute quick charge in the case restores up to 3 hours of music playback. The charging case supports both USB Type-C wired charging and Qi wireless charging, while the earbuds carry an IP54 dust and splash resistance rating, Bluetooth 5.3 dual-device multipoint connectivity, and pressure-sensitive force-sensor stems. When comparing listings in Headphones & Speakers on BiponiBD, confirm your preferred finish (Star Gold or Space Black) and install the official Xiaomi Earbuds app on Android to configure LDAC and head-tracking modes.
