The sound quality of sony Xperia X is ok-ok, it is a little bit less louder than other phones.
It is not user friendly as it hangs a lot and it has quad core processor where other smartphones have octa core processor in this price range.
There is nothing new about Its style and design
Sony tried to experiment with this phone but it failed badly.
In other features it lacks some features like no HD display, no fast charging and some hardware issues too.
Its look is not upto the standards of a sony mobile and it is a bit heavy to carry and feels like you are robbed by purchasing this smartphone.
It is not value for money as it does not have fast processor, no hd displays and it is a bit overpriced on the other hand you can find more features than this in other phones which will cost you much less than this phone.
