IPhone 7 doesn’t have a headphone jack?
It has been rumoured that the new iPhone no longer has the ordinary 3.5mm jack. Instead, the noise output will probably be from the lightning cable port or by bluetooth. The iPhone will probably come with the standard headphones but will go on the lightning port. Our source claims that there will be some sort of noise cancelling technology from Wolfson Microelectronic which will remove background noise (or try to!).
Having acquired Beats, Apple could release addition headphones that could be bought separately. There will probably still be headphones included with the box though.
