Reviews for the Xiaomi Redmi K40

Xiaomi Redmi K40 Gaming Audio review: Loud and artifact-free
Source: DxOMark English
Those looking for an adept tool for recording in a variety of situations would be wise to look elsewhere. In playback, the Xiaomi Redmi K40 Gaming will please gamers looking for loud volume, decent spatial attributes, and good performance on dynamics sub-attributes like attack and punch.

Redmi K40 Series Review: Would Be Affordable Flagship Phone of 2021
Source: Igeekphone English
Therefore, for the K40 series of the “full series of rising cups”, I think it can be regarded as an attempt by Redmi to develop upwards. Perhaps in the future, we can see that Redmi will have more “lifting cups” products and continue to consolidate and improve itself in the industry’s market and position. There is no doubt that the K40 series can and must make a good start for Redmi’s new 10-year road.
