I think that the redmi 4a has an average sound quality as it cant feel good in listing the high base music because the base beats are not clear.As it is a xaiomi device it has a great user interface which is very easy to use and also very user friendly and good looking with many features.it is a low budget phone and also has the features like that only. It looks simple not slim and also does not has a 2.5 d curve glass so which we cant feel nice on holding it. There are also some other features like camera quality is not so good and has a low quality video recording.it is not as expected from xaiomi so it is not a value for money phone.
