The AirPods 2 are set to have more features and be more expensive. These include better noise compensation and moisture protection. The wireless range is also set to be increased. It is also possible to integrate biometric sensors.
According to a recent report from Bloomberg, Apple will not present the second generation of the popular headphones until 2019 at the earliest. Although Apple's stocks have already dropped, which usually indicates a new product generation, there will be no new AirPods this autumn. The reason for this is the great popularity of the small plugs and the associated sales success. This would be enough for the iGroup to submit a new edition next year at the earliest.
Blayne Curtis of Barclays shares Bloomberg's assessment. Apple may add the "Hey Siri" function via a software update, provided the W1 chip has enough power left for it. In the meantime, the iGroup will offer the new charging case for the AirPods as an option. This would make wireless charging possible, as already announced by Apple. It remains to be seen whether the reports turn out to be true.
