Sound reception of apple iphone 6 is very good but if you are talking to someone online make sure the connection is good. It has got a user friendly interface with a very fast interface speed which makes it different from other brands. Look of the phone is classy and the curves on the metal body make it supercool. Unlike the older iphones it has 3.5mm audio jack and yes it also has bluetooth function. The phone makes you feel different from others and make you feel happy. At starting the rates were high but now the rates are even less than starting rate of apple iphone 4g.
