The fourth generation of TWS headphones from Xiaomi / Redmi, which were introduced in the fall of 2022. Headphones belong to the middle price segment and are designed for users who are looking for universal wireless headphones with good autonomy, advanced headset capabilities and built-in noise reduction. Redmi Buds 4 are equipped with classic 10mm dynamic drivers with a frequency range of 20Hz to 20KHz.
Compared with the third generation, Xiaomi engineers have improved the adaptive noise reduction algorithm: ANS uses a combination of multiple microphones and algorithms to filter ambient noise in real time, and then filters the noise according to the user's settings. According to the manufacturer, the ANS capabilities in the 4th version can reduce the noise level by up to 35 dB.
To connect to the signal source, an energy-efficient Bluetooth 5.2 protocol is used with a range of up to 10 meters. The manufacturer guarantees 3 to 6 hours of battery life (depending on the volume and use of ANS). Using the charging case extends the battery life up to 30 hours. The case itself is powered from the mains using a USB-C cable. Fast charging is also supported: five minutes is enough for uninterrupted work for an hour. The headphones are compatible with both Android and iOS devices. On top of that, they boast IP54 water resistance, Multipoint support, auto-pause, and support for Siri and Google voice assistants.

AI-powered noise reduction
Xiaomi Redmi Buds 4 are budget TWS headphones that are equipped with an adaptive noise reduction system based on artificial intelligence and provide high quality communication in various conditions. The headphones have two built-in microphones - internal and external, which allows you to clearly separate the user's voice from ambient noise. A transparency mode is also available, which can work in conjunction with noise reduction. Automatic adaptation to environmental conditions allows the headphones to provide optimal call quality. The user can also select one of three noise reduction modes (light, deep, balanced) manually. In terms of sound quality, there is rich bass and clear vocals.
Variability of control
Xiaomi Redmi Buds 4 connect to the device via Bluetooth and provide good synchronization of music and voice, as well as no delays in data transfer, which is important for games. The headphones are controlled by touch surfaces that are well thought out. When installing the Mi Buds M8 app, the user can configure touch options for each earphone individually, as well as other parameters such as transparency, volume, noise reduction, etc. A convenient feature is auto-pause, which is activated when the earphone is removed from the ear. There is also a function to search for headphones within Bluetooth range.
The autonomy of the headphones is average and is up to 30 hours when paired with a charging case, which allows you to use them over the weekend without the need to charge. If charging is still required, fast charging will allow you to get 1 hour of use in 5 minutes of charging.
