According to the analyst of KGI Securities Mr. Ming-Chi Kuo, Apple is going to release the advanced version of AirPods in 2018, and in the second half of 2018, there is probably going to be a major revision in them as well.
The AirPods were launched for the first time by Apple back in 2016, but since then Apple has been struggling to maintain the higher demand of AirPods. Still, Kuo states that the estimated shipments for AirPods will have more than 100% growth in 2018 and their sales will reach more than 28 million units next year.
Any further details about the new design and features of upcoming AirPods have still not been revealed by Apple, and even Kuo has declined to comment on that at the moment. But one thing is certain, the new AirPods will feature the smaller quartz component. The average selling price of the new AirPods can also be a bit higher as compared to the current version available in the market.
