Redmi Buds 4 Active deliver solid performance at an affordable price point. They feature 12 mm dynamic drivers tuned by Xiaomi’s Acoustic Lab for enhanced bass and balanced acoustics. While lacking full ANC, they offer ENC (Environmental Noise Cancellation) for clearer voice calls. Connectivity is powered by Bluetooth 5.3, with seamless pairing via Google Fast Pair and a dedicated low-latency mode (~60 ms) optimized for gaming and video playback.
Each earbud is ultra-light at just 3.6 g, and they’re housed in a compact case totaling 41–42 g, making the entire kit extremely portable. The earbuds are IPX4-rated, offering splash protection but not full water resistance.
Battery life is impressive for the price — up to 5 hours per earbud (34 mAh) and around 28 hours total with the 440 mAh charging case. Fast charging is supported: 10 minutes charge yields ~110 minutes playback, and a full charge completes in about 1.5 hours. Control is via touch input, and the product supports basic customization through the Xiaomi Earbuds app
