Sound quality is above average. If you are using it at ear piece than you can get good sound. This operates windows operating system so it cause little bit problem for new users. If I talk about desing it is not so thin and this has some roughness screen. This is for daily use user who use only basic features. About range of features this has less ram as 512mb and internal storage 8gb that is not enough. This has durability. If you are looking for windows phone than search better than it. I recommend it no value for money.
