Why newer Fairphone models do not have an audio jack

Removing the traditional 3.5mm audio jack gives us space inside the phone to make key hardware improvements. Without this opening, we can fit a larger battery, design a slimmer smartphone, and preserve room for repairable spare parts. Removing the port also helps seal the phone against water and dust, allowing modern models to reach IP ratings like IP55 on Fairphone 4 and IP68 on Fairphone 5. Moving audio to the USB-C port and Bluetooth connections lets us build a more durable phone that lasts as long as possible.
