The Xiaomi Redmi Buds 4 weigh just 4.5 g and fit perfectly in the ear. With the 10 mm dynamic drivers, the Redmi Buds 4 produce a rich bass, reach high frequencies and consistently high sound quality. Thanks to the hybrid active noise cancellation technology, the feedforward and feedback microphones work together to effectively filter out background noise. Whether outdoors, on the bus or in the subway, up to 35 dB of noise cancellation can be achieved with just one press of a button. When you take the earbuds out, the music is paused and it is restarted when you put them back in. The Redmi Buds 4 achieve a battery life of up to 6 hours. In combination with the charging case, the running time can be extended to up to 30 hours.
