Counterpoint Research:

Apple expected to lead the true wireless hearables market, selling more than 100m units in 2020. Competition for second place will remain fierce, especially in the premium market.

From the hearables Wikipedia page:

The neologism “hearable” is a hybrid of the terms wearable and headphone, as hearables combine major assets of wearable technology with the basic principle of audio-based information services, conventional rendition of music and wireless telecommunication. The term was introduced in April 2014 simultaneously by Apple in the context of the company’s acquisition of Beats Electronics and product designer and wireless application specialist Nick Hunn in a blogpost for a wearable technologies internet platform.

I read “hearables”, I think AirPods. Apple so dominates this market. If you’re interested in the history of the term and the market, the Wikipedia page is a fascinating read.
