The smart-phone form factor is largely determined by the rectangular screen, and for the cameras to be useful, they have to be on the back and/or front.
The keyboards are very different in design between Google and Apple, and many phones don’t have home buttons. Some even have more buttons.
Conversely, there’s nothing about ear-buds that force you to use white plastic with black grills for the holes, EarPod-style stems, or metal tips on said stems, nor a white round-rect pill box to store the things in.
The lazy OnePlus people chose to copy those features, making their product look like Apple’s.
The stems come from the antennae required for a solid connection, IIRC approximately 30mm long. The OnePlus buds are available in a number of colors. Metal tips on said stems is also a design decision to allow charging by slotting them into the container. The form factor of the container follows from the design of the stems.
well tbf the earbud form factor is largely determined by the shape of your ear.
Also the product in question come in several colors, white being just one of them. It's kind of ridiculous to rule that the earbuds they make cannot come in white colors because some other brand already does?
