Its the next generation to the iphone 5s. its design is quite different from iphone 5s and its size is also different from iphone 5s. sound reception of this phone is equal to the iphone 5s because I think the mike and the speaker both are of same quality. its a litle bit slim than iphone5s but large in size than iphone 5s. it has a new color to the iphone segement which is rose gold. if we talk about the features it has a good camera as compared to the iphone 5s and also the front camera is better than iphone 5s. this phone is bit costly than its features and generation.
