Negative impacts for Apple: A recent YouTube video showed how the lack of headphone jack could reduce music listening either due to having to use an adapter for certain situations or having to charge the headphones which discourages listening. That could decrease Apple Music usage. The existence of better alternatives with a headphone jack could encourage people to switch, decreasing sales of the iPhone 7. Although this could be counteracted by people opting for the SE/6S instead, no headphone jack and a similar design makes it likely to see a dip in sales compared to other iPhone releases. Positive impacts for consumers: Better wireless and more lightning options will hit the market. The advantages that come with lightning headphones. Other impacts: Phone manufactures will think it's acceptable, as they did with camera bumps, and may remove the headphone jack on their phones, as we can already see by phones like the Moto Z. More USB-C headphones will be available. Any possible impacts I haven't mentioned?
