Redmi Buds 4 Pro
By the way, the Buds 4 Pro is Redmi’s annual flagship TWS headset. Now, its noise reduction depth is 43dB. It supports a dual-transparency mode. Apart from this, in the vocal enhancement mode, it can not only filter out environmental noise but also help users make calls.
The Redmi Buds 4 Pro also supports an intelligent anti-wind noise mode. There is a hardware-grade metal wind-proof mesh, which can greatly reduce the wind energy before the wind enters the microphone. This is the most effective anti-wind noise structure at present. Combined with the wind noise reduction algorithm, the ambient wind noise can be automatically identified within 3s and quickly offset.
Our protagonist also adopts the latest Bluetooth 5.3 protocol and supports LC3 encoding. You can effectively use it with the Redmi Note 11T Pro+, Redmi K50 / K50 Pro.
In terms of sound quality, the new earphones use a coaxial double moving coil unit. The latter consists of a 10mm aluminum-magnesium alloy diaphragm large moving coil as well as a 6mm titanium diaphragm treble moving coil. They effectively expand the overall frequency response range, making the treble clearer.
