Step 1: Remove headphone jack that uses mostly right angle connectors placed on the corner of the phone that goes at the bottom of your pocket so it doesn't bend anything
Step 2: Make the phones absolutely gigantic so they take up your whole pocket (very important step)
Step 3: Sell people shitty USB DACs with straight(!) USB connectors that go right in the middle of the phone at the top of your pocket sticking out so it's impossible to not bend it
