Redmi Buds 6: Quick Specifications
Redmi Buds 6 Overview
Redmi Buds 6 are designed as an affordable feature-rich TWS option with an emphasis on audio hardware, active noise cancellation and battery endurance.
The standout hardware feature is the dual-driver configuration. Xiaomi combines a 12.4mm titanium-coated dynamic driver with a 5.5mm micro-piezoelectric driver in each earbud.
The earbuds also offer three ANC modes, Transparency Mode, AI-powered call noise reduction, in-ear detection, dual-device connectivity and customization through the Xiaomi Earbuds app.
Dual-Driver Audio System
Unlike conventional single-driver earbuds, Redmi Buds 6 use two acoustic drivers designed to cover different parts of the frequency range.
The larger 12.4mm driver is designed to provide fuller low-frequency reproduction, while the 5.5mm micro-piezoelectric unit is intended to contribute additional high-frequency detail.
Sound Quality & EQ Customization
Xiaomi provides multiple sound profiles through the Xiaomi Earbuds application. Users can choose from preset sound options and create a custom EQ profile.
Xiaomi also provides a custom EQ option, allowing listeners to adjust the sound according to their personal preferences.
49dB Hybrid Active Noise Cancellation
One of the main selling points of Redmi Buds 6 is their Hybrid Active Noise Cancellation system, rated by Xiaomi at up to 49dB of noise cancellation depth.
Xiaomi specifies a noise-cancellation range extending up to 2000Hz and provides three ANC modes: Light, Balanced and Deep.
Transparency Mode
Transparency Mode lets external sound pass through the earbuds, allowing users to remain aware of conversations and their surroundings without removing the earbuds.
The Xiaomi Earbuds application provides ambient-sound and voice-focused options for different listening situations.
Call Quality & AI Noise Reduction
Redmi Buds 6 use a four-microphone system with AI-based environmental noise reduction for calls.
Xiaomi states that its anti-wind noise algorithm is designed to reduce wind interference in conditions up to 9m/s.
Independent Spatial Audio

The feature can be useful for supported movies, music and games where a wider spatial presentation is desirable.
Gaming & Low-Latency Mode
Redmi Buds 6 include a low-latency mode with latency of approximately 60ms according to Xiaomi's specifications.
Lower latency can help reduce the perceived delay between an action on screen and the corresponding sound, which is useful for gaming and video playback.
