Sound quality is good at ear piece and if you are using it for loud than this average. 3.5mm jack can be used as output. If I talk about use, this is easy to use for ios user and non user.
It has paritial metal body. And design is good. This has normal feature. Ram is 1 gb and internal memory 16gb. This is not sd card supported. This creates some problem. It should be supported sd card. Means you can use only limited memory. This is reliable. If you are developer than this is not for you.
Worth for money for iphone users.
