They aren’t really designed for conference calls. It’s more for listening to music and answering a few calls when they happen. AirPods are more of a light workout or entertainment headphones. Jabra, Plantronics, and the like are for conference calls.
I do use them for conference calls but I know they have limited capabilities. My 14 hour Jabra headset will do just fine and have noise cancellation.
The Airpods sound...not great. Especially when compared to the Sennheisers. Still, I am not going to carry a large pair of headphones (or a dac/amp) everywhere I go just so I can have the very best (tm) audio experience. The reality is that most listening environments are _terrible_ and much of the quality of a given audio device is lost. Airpods check a lot of boxes that are not checked by my other headphones.
At this price point you are paying form factor and lightweight. Bose and Sony have much better headphones at a similar price point. Both are much bigger and may have cords but the quality is much better. They last longer too.
At this price you're paying for recognisability and affluence signalling. Apple will be able to launch a 'limited series' of 'black airpods with gilded touch rings' - with the colour being the only differentiator from the regular product - at a 50% price increase and see considerable sales.
