Apple’s AirPods will once again dominate the market for truly wireless headphones in 2020, according to a market research firm. And sales will hit 100 million units this year.

The only real question is which company will come in second in this market.

Apple sold almost 60 million AirPods wireless headphones in 2019, according to a market-analysts firm. That’s a dramatic increase from the 35 million the company is estimated to have sold the year before.

And Apple took the lion’s share of 2019 sales of totally wireless (TWS) headsets.

AirPods contribute as much to Apple’s bottom line as the iconic iPod did at its peak, according to an industry analyst. And Apple Watch long since passed that milestone.

Combined, Apple’s Wearables and Home products are expected to far outsell Mac and iPad this quarter.

Apple’s wireless earbuds are selling better than most people realize. The company is on track to sell 50 million pairs by the end of this year, according to an industry analyst.

That’s up from 35 million in 2018. The product only debuted in 2016.
