Market research firm Slice Intelligence estimated that AirPods, Apple's $159 wireless earphones, took one out of each four dollars spent online on wireless headphones in December 2016. Launched on December 13, AirPods grabbed an estimated 26 percent share of online revenue in the wireless headphone market, beating out Apple's premium audio brand Beats which captured an estimated 15.4 percent of the market, down from 24.1 percent between the start of 2015 and December 13.
In other words, Apple has managed to capture one-fourth of the wireless headphones market since the launch of AirPods. And if you also count Beats sales, the Cupertino company took almost 40 percent of online revenue in the wireless headphone market.
