Xiaomi Redmi Buds 4 - a budget headset with support for ANC and Transparency Mode. The operating time of each Bud is 6 hours, of course without ANC and Transparency Mode, and the case can charge them 5 times, which gives us a total of 30 hours. The headphones have an IP54 certificate, which means protection against splashes and dust. The headset has three levels of sound suppression: Light Mode, Deep Mode and Balanced Mode - which makes the use of the headset particularly comfortable in different environmental conditions.
