Beats took its time getting untethered. The last addition to the Powerbeats line arrived in late 2016, right around the same time as the original AirPods. The product shared Apple’s W1 chip, further cementing its place as part of the company, with instant iOS syncing. But the products were once again yolked together with a cable.

A few weeks after the release of the second-generation AirPods, Beats finally unveiled the Powerbeats Pro, the company’s first fully wireless earbuds. Comparisons with Apple’s latest are inevitable. After all, Apple and Beats are one big happy family now, sharing technologies and working together in some capacity.
