A key difference between the AirPods 4 and Apple’s previous model of “regular” AirPods is the shape of the housing that goes into your ears. The company says it analyzed thousands of ear shapes and over 50 million data points generated by 3D modeling to refine the curves on this new set of buds. Specifically, Apple adjusted the edge of the lower counter and narrowed the overall width for a more secure and more comfortable fit for more people. The company also put the H2 chip in the stem, allowing for a more compact design and improving both airflow and acoustics.
