We have seen the whole Smartphone and noticed something unusual , The Smartphone doesn't have a "Headphone Jack" .
You might be wondering ? Why ? Then How will one attach headphones ?
The answer is , Both the Smartphones comes with USB Type C , so their audio-out happens through those. The Smartphone might come with a USB Type C earphones .
Also Both phones will come with usb to 3.5mm jack adapter in the box. USB is the future for audio, 3.5 jack will die slowly
But we will not be able to use headphones while charging ( due to same port ) .
