Apple might insist removing the headphone jack from the iPhone 7 was an act of "courage," but Incipio sets to satisfy customers who think otherwise with the OX, a case featuring the humble 3.5mm connector.
As seen at CES 2017, the OX case comes in iPhone 7 and 7 Plus variants. It fits over the Lightning port and adds an additional Lightning port as well as the aforementioned 3.5mm jack for the use of traditional headphones. The case is admittedly bulky, but it does allow simultaneous charging and music listening without need for an additional adapter or dongle.
In addition the case promises to protect the iPhone display and body from drops through a shock-absorbing exterior.
