Apple's new iPhone doesn't have a headphone jack, in its place is only a Lightning port that's also used to charge the battery. Even without the headphone jack, people can still listen to music privately by using AirPods which are sold separately.
With this release, many people expressed their disappointment with the removal of the headphone jack. One of these people is Steve Wozniak, the co-founder of Apple. He told The Australian Financial Review in August this year that removing the headphone jack was "going to tick off a lot of people."
But now, he seems to have changed his mind. He now thinks that Apple's decision to drop the headphone jack in exchange for using a Lightning port for audio is right. Perhaps, this is the right path that Apple is taking, as it speaks of innovation and change. If it was not to remove the headphone jack, then the company's purpose will be questioned, making it not that innovative.
According to Tech Radar, Wozniak said that he's never used the headphone jack and that he thinks not many people use it. Adding that to those who use it, they can buy a little adapter dongle. As Apple marketing chief Phil Schiller said at the iPhone 7 launch, "Maintaining an ancient, single-purpose, analog, big connector doesn't make sense because that space is at a premium."
What the headphone jack does is that it carries an audio signal that allows the user to hear sounds. It needs its own power amplifier and digital audio converter, which were built into headphones. Removing the jack makes room for other things, such as a second speaker.
Schiller said the decision to drop the 3.5mm jack was down to courage. However, even if it is acceptable that the change was brave, "courage" is not appealing to customers. It is much better to say that Apple removed the iPhone 7 headphone jack for progress.
